DOUG AAMOTH. JavaScript, NetUSB, Log4Shell, FTC…
All that and extra: it’s the Bare Safety podcast.
[MUSICAL MODEM]
Welcome to the podcast, everyone.
I’m Paul; he’s Doug…
PAUL DUCKLIN. [LAUGHING] I feel you made a real mistake there, didn’t you?
DOUG. I did.
DUCK. It wasn’t truly a joke.
DOUG. *I’m* Doug… I’m on autopilot, as all the time, for the primary minute of the present.
DUCK. Nicely, we’re going to be speaking about loads of software program bugs… it’s straightforward to make that sort of mistake.
DOUG. We do have lots to speak about, so we’re going to get into it.
We’ve obtained one thing of a lightning spherical at this time; a variety of tales to cowl.
And as , we like to begin the present with a Enjoyable Reality: should you’re superstitious about Friday the Thirteenth, you’re not alone except you reside in Greece, Spain, or Italy.
Greece and Spain think about Tuesday the Thirteenth to be the unluckiest day; Italians are cautious of Friday the Seventeeth; and Paul, as , we’ll tie this again within the This Week In Tech Historical past section later within the present.
DUCK. Triskaidekaphobia!
DOUG. I’ve seen that written a number of locations, and I’m glad you mentioned it out loud as a result of it’s nearly unattainable to learn should you haven’t heard it earlier than…
DUCK. Τρισκαίδεκα… it’s simply the Historical Greek phrase for 13, with the phrase for concern.
So truly, that’s concern of 13, somewhat than essentially simply Friday the Thirteenth, however they sort of go collectively.
DOUG. A day when spooky and odd issues occur.
And talking of spooky and odd, this “JavaScript developer’s” story is wild!
DUCK. I don’t know whether or not it’s spooky, however sure, it’s odd. Maybe a bit of bit unhappy.
DOUG. So what occurred right here?
DUCK. Nicely, it was what you may name a provide chain assault, the place folks suck code written in JavaScript into their initiatives – from NPM, or GitHub, or wherever they get it, from an open supply module that’s consumed by a great deal of completely different initiatives, issued below the MIT Open Supply licence.
So that you’re free to make use of it, supplied you don’t declare it’s yours – you may even use it in business code.
And the developer of two such initiatives, faker.js and colours.js, all of the sudden determined he’d had sufficient.
He’d given some indication, a few years in the past, that he was a bit bored with doing all this work and never getting paid…
…just like the the well-known XKCD cartoon, Doug.
DOUG. [LAUGHS]
DUCK. “All the things’s propped up by this skinny little pillar of program, maintained tirelessly by some random particular person in Nebraska since 2003” – *that* XKCD cartoon.
DOUG. Sure.
DUCK. This man clearly determined, “Nicely, I’ve had sufficient.”
So, for faker.js, he simply mainly pulled the plug on the entire thing – he eliminated all of the supply code.
He created, should you like, a remaining model of the mission that has no supply code in it; it has the remark “Endgame”; and it simply says within the README, “What occurred to Aaron Schwartz?”
He was the well-known hacktivist who very sadly dedicated suicide after being arrested for taking a complete load of recordsdata – educational papers that he felt shouldn’t be behind a firewall, however the regulation felt in any other case.
In order that’s what he did with this faker.js
And though it’s a bizarre identify for program, it truly was very helpful factor to have as a result of it creates faux knowledge for you.
You spoke about that in a latest podcast, didn’t you, Doug?
Concerning the significance of not utilizing actual knowledge so that you simply don’t get into privateness bother.
Nicely, he pulled the plug on that one, so should you up to date to the newest model, it’s all gone.
You don’t should replace – you’re legally allowed to maintain utilizing the older one – however clearly, he’s determined it’s time to get out of Dodge Metropolis.
However with colours.js… sadly, he took a much less comprehensible method, in that he issued a brand new model that included an infinite loop, mainly inflicting it to print weird-looking rubbish once you ran it, as a substitute of simply letting you add colours to your console output.
You know the way folks like colours to spotlight phrases like ERROR, WARNING, no matter.
However should you accepted this replace robotically, as a part of what you may name your provide chain, then all of the sudden your program would undergo a Denial of Service as a result of it will get into this loop that ran from a beginning worth of 666…
DOUG. [LAUGHS]
DUCK. …as much as, however not together with, the JavaScript worth Infinity.
This loop prints out “testing, testing, testing, testing, testing” with a complete load of rubbish added.
You could possibly say that wasn’t a really good factor to do, however you didn’t have to simply accept the brand new model, and the code was in there so that you can see: it wasn’t hidden in any manner.
It’s open supply you might go and evaluate it.
Anyway, some folks obtained hit and needed to revert to the previous model, and this began a complete chain of feedback on his GitHub account.
I consider he’s been locked out of his GitHub account, maybe understandably, however there are a whole bunch of feedback on there.
Some folks going, “Yeah, I’m with you, bro’; I get the place you’re coming from”, and different folks saying, “You realize what? Most likely a step too far.”
DOUG. Take into consideration what number of business software program packages depend on issues like this…
DUCK. You nearly mentioned Log4j there, Doug.
DOUG. [LAUGHS] Let’s speak about that a bit of later.
DUCK. Nicely, I’m wondering if the timing of this was maybe not precipitated by the the fuss over Log4j>
Possibly that’s what provoked this chap?
As a result of my understanding is he did attempt to commercialise the faker.js toolkit, which could be very helpful; fairly a considerable physique of code that would create life like knowledge of all kinds.
He did attempt to commercialise it, and create on-line companies that individuals who wished to may pay him, however it appears that evidently that didn’t work out for him, and so it wasn’t actually sustainable.
So he pulled the plug on that one.
However sadly, he poisoned the effectively on the opposite mission, and that’s the place we stand.
DOUG. I suppose this resurfaces the query of the the concept of a Software program Invoice of Supplies, or an substances record, if you’ll, for customers or folks which can be going to purchase your software program…
…to allow them to see what number of open supply parts it has, or the place all the pieces’s coming from.
DUCK. Sure, perhaps that’s the silver lining on this.
Log4j didn’t clear up the underlying drawback: that function was added to Log4j, what, in 2013?
And no person observed it till now, after which after they did, “Oh golly, how dare you?”
Nicely, you took the code into your software program years and years in the past with out noticing it had this drawback, and also you didn’t pay for it; perhaps it’s a bit of excessive to recommend that it was anybody’s fault however your individual, since you obtained caught out.
So perhaps the silver lining is that, though you might say it was a little bit of an childish factor to do, perhaps it would assist us all settle for, such as you say, a Software program Invoice of Supplies – “listed substances”.
Possibly that’s a good suggestion.
DOUG. All proper, plenty of good dialogue there.
That story known as JavaScript developer destroys personal initiatives in provide chain “lesson” at nakedsecurity.sophos.com
So you may head over there to learn and opine.
And now we’re going to speak about NetUSB.
I bear in mind the fun of plugging my printer immediately into my residence router through USB, what number of years in the past and saying, “Wow, we’ve made it! The expertise has lastly reached its apex!”
DUCK. NetUSB is a product you could license from an organization in Taiwan referred to as Kcodes.
They declare of their advertising and marketing materials that over 20% of worldwide networking gadgets have embedded Kcodes code in them now, so it feels like they’ve been fairly profitable.
And NetUSB is, should you like, a generic USB virtualiser.
So it’s not simply you could plug in a centralised exhausting drive or NAS, or a printer, such as you did.
NetUSB can deal with different issues like TV tuners, audio gadgets, all kinds of stuff, centrally.
So there’s a type of digital USB cable that runs over your community, between your laptop and (sadly) a particular kernel driver in your router…
…a driver that turned out to have a bug in it that would, in idea, have allowed nearly anyone to take over your router.
Oh expensive.
DOUG. Oh expensive, certainly.
DUCK. So, that bug was discovered by a researcher referred to as Max van Amerongen at Sentinel One.
Apparently, he was taking a look at coming into the Pwn2Own IoT hacking competitors for 2021.
He noticed that Netgear had a tool on the record, so he thought, “Oh, I’ve regarded to these gadgets earlier than; let me have a look.”
He discovered that there was a kernel driver that was listening on TCP port 20005… that quantity appears to be arbitrary, in order that’s not a dependable indicator that you’ve got this drawback, but it surely is perhaps a place to begin if you understand how to do port scanning.
And Max figured, “Hey, kernel driver itemizing on all community interfaces – localhost, LAN and WAN? If there’s a vulnerability in there, it is perhaps remotely exploitable. That’s the place I’m going to begin focusing.”
And so he dug into the code there.
As you’d think about, one thing like NetUSB – it’s going to have a variety of completely different capabilities it helps.
For those who consider HTTP, effectively, that’s obtained dozens of instructions: GET, POST, HEAD, OPTION… however one thing like NetUSB, with dozens of various kinds of gadget, with dozens of various options, most likely helps a whole bunch of various instructions.
And he discovered that the command 0x805F – I feel that’s simply arbitrary, 32863…
That command, when it processed the information that was to be despatched for it, had a nasty little bug, Douglas,involving the quantity 17.
Mainly, the bug goes like this.
Whenever you wish to run this command – the command is one thing to do with a message; I don’t know what the command does, as a result of it’s truly the pre-processing that causes the issue, not the command itself…
…the very first thing that the kernel driver does is say, “OK, I’m going to wish some knowledge from you. Inform me how a lot knowledge you’re going to ship,” and it accepts a four-byte worth. (You possibly can see the place that is going…)
Then it allocates that a lot reminiscence.
Now, that sounds dangerous as a result of it doesn’t do a size test.
What if the particular person says, “Oh, I wish to allocate three gig of RAM?” [LAUGHTER]
Nicely, you think about, on the typical residence router, it’s simply not going to work, and it’ll fail gracefully.
The issue is, should you say, “I need 4GB minus one byte,” in different phrases FFFFFFFF in hexadecimal.
Then, as a substitute of attempting to allocate that many bytes, which clearly received’t work as a result of a 32-bit router is not going to have 4GB of RAM at its disposal at hand to you…
… what the code would do, it will say, “Nicely, I’m going to allocate as a lot reminiscence as you need in case you want that a lot, even should you don’t use it. And I would like 17 additional bytes for my very own short-term use.”
So, it will allocate a really, very giant constructive, unsigned integer *plus 17 bytes* of reminiscence.
This might wrap round, millennium bug or automotive odometer model.
And so an attacker may say, “I need you to allocate me 4GB-1 bytes of RAM, and that may imply that I can ship you messages any measurement as much as that quantity in future.”
However the kernel would then allocate a buffer of solely 16 bytes, due to the integer overflow.
Then the kernel would say, “Proper, ship me your knowledge,” and also you ship it as a lot as you need…
After all, should you then ship it greater than 16 bytes, which is by chance all it allotted, you’ve obtained a buffer overflow contained in the kernel!
Thanks for coming; recreation over.
DOUG. OK, feels like we have to look forward to a firmware replace!
DUCK. Nicely, the excellent news is that this was responsibly disclosed.
The explanation that it was solely written about this yr, though the work was completed again in the midst of 2021, is that this was responsibly disclosed to the corporate that makes the NetUSB product, after which to all of the distributors that is perhaps licensing their merchandise.
So, they have been all conscious that there was this bug and that they wanted to repair it.
So it was responsibly disclosed, and patches can be found.
The one drawback is: how do you discover whether or not you’re weak?
As I discussed earlier, you might attempt utilizing a program like Nmap or one thing, a port scanner, and seeing should you’ve obtained port 20005 open in your router, which might be an excellent trace that you simply might need this factor, as a result of that’s how the researcher discovered it within the first place.
However, after all, that’s only a symptom: whether or not you will have that port open or closed doesn’t imply that you simply do or don’t have the bug.
So, when you’ve got a router that helps this NetUSB function, which helps you to plug in not simply printers however nearly any USB gadget centrally, then go to your router vendor’s web site and test whether or not there’s an replace.
DOUG. OK, and we’ve obtained another recommendation that may assist us mitigate such malfeasance sooner or later.
DUCK. Sure, the opposite recommendation we put within the article was to not customers of residence routers that is perhaps in danger, the place actually all we will say is, “Patch early, patch typically; test to see whether or not there’s a patch obtainable.”
We put in some recommendation for programmers: three fast issues.
Firstly, don’t hear on all community interfaces by default, except you actually need to.
Secondly, all the time test the outcomes of integer arithmetic, particularly when it pertains to reminiscence allocation.
And the third tip is to test for integer underflow, in addition to for integer overflow.
For those who think about working an old-school automotive odometer backwards, the quantity earlier than 000000 is 999999, not -1, as a result of automotive odometers can’t do destructive numbers.
Don’t suppose, “There are sure to be 17 bytes spare,” as a result of there may not be…
…you owe it to your customers to test.
DOUG. OK.

Now it’s time for This Week In Tech Historical past!
We talked about Friday the Thiteenth earlier within the present….
DUCK. I’ve obtained an inkling the place that is going, and I feel that it’ll relate to laptop viruses, Doug. [LAUGHTER]
That’s my suspicion…
DOUG. How *did* ? [LAUGHTER]
This week, on Friday, 13 January 1989, a Friday the Thirteenth virus contaminated computer systems throughout Britain.
This was not the primary Friday the Thirteenth virus, and it might or could not have been a variant of the so-called Jerusalem virus earlier than it, which was a time-bomb virus that was set to go off beginning on Friday the Thirteenth of Might 1988, which was the newest Friday the Thirteenth earlier than January 1989.
Each viruses slowed down machines, however left COMMAND.COM alone.
And Paul, you will have some nice color about all of these items since you lived by means of it. “You have been there, man.”
DUCK. How historical past repeats itself!
A number of classes from these days we will take up nowadays, however the one about COMMAND.COM is sort of fascinating.
From reminiscence, one of many very earliest file infecting viruses within the DOS world – I feel it might have been the Lehigh virus from the US – it was very apparent, as a result of when it contaminated the COMMAND.COM file, there only some variants of COMMAND.COM, and a few folks had memorized the scale of that file.
So, phrase rapidly obtained round, “Hey, this virus enterprise is trivial to cope with. All you must do is watch the scale of COMMAND.COM, and if it modifications, you’ve obtained a virus!”
And the inference folks have been invited to make was subsequently: if it *doesn’t* change, you *haven’t* obtained a virus.
So, what did the virus writers begin doing nearly instantly?
DOUG. [LAUGHS]
DUCK. They contaminated each file *besides* for COMMAND.COM, as a result of that was the one everybody was specializing in.
But it surely does present that this was a distinct period… when you might identify a virus after a whole *metropolis*, on the idea that there have been so few viruses that what’s they likelihood they’d ever be one other one from the identical place?
DOUG. Sure, occasions change, and never all the time for the higher.
Talking of occasions altering, it appears that evidently Honda is both having its personal little Y2K second, or it inadvertently constructed one thing that works like a time machine.
DUCK. Love your work there, Doug – that’s an excellent segue.
DOUG. Thanks!
DUCK.I knew what was coming subsequent, and I didn’t predict that.
Sure, the Honda time machine.
It’s positively Again to the Previous, isn’t it? Not Again to the Future.
Apparently, house owners of Honda vehicles of a sure age – not model new ones, and never model previous ones, both; the vehicles should be apparently someplace round a decade previous…
…on New Yr’s Day 2022, when folks would begin their vehicles, after a the whereas the clock would set itself again to someplace round midnight on 01 January 2002.
And I shouldn’t say this, as a result of it’s a merciless factor to do, however I’m going to say that should you can’t bear in mind 2002…
DOUG. Oh, no, no, noooooooooooo….
DUCK. Am I allowed to do it?
DOUG. No!
DUCK. Let’s simply say there was a music on the charts with lyrics that go, “La la la, la la la la-la, la la la la-la la la-la”, by the diminutive Aussie pop star Kylie Minogue – that’s how far again we’ve gone.
And nobody fairly knew why.
One of the best guess to this point appears to be that it pertains to what’s referred to as GPS rollover, in the identical manner the Millennium bug was attributable to folks going, “You realize what? We’re simply going to deduce 19 and can use two digits for the yr.”
Nicely, after all, GPS was invented within the Nineteen Seventies, and bandwidth from these faraway satellites could be very, very restricted.
And so they figured, effectively, what we’ll do is we’ll run on intervals of 1024 weeks as a substitute of years.
So, there’s a “week quantity”, and there are solely 10 bits obtainable for the week quantity.
So each 1024 weeks, old-school GPS gadgets return to what you may name Day Zero.
I name them “kiloweekaries”,” and people kilowwekaries go from 1980 to 1999; 1999 to 2019; and 2019 to 2039.
Now, there was an notorious kiloweekary reset on 06 April 2019, the place folks with previous GPS receivers have been questioning, “Will they leap again to 1999?”
Some did, some didn’t.
However after all, just like the Millennium Bug, you don’t should get hit by this *solely on the actual rollover interval*.
As you bear in mind, with the Millennium bug, what a variety of software program did was to imagine something earlier than 50 truly referred to the following millennium.
Subsequently 50 means 1950, however 49 means 2049 – so you continue to have a Millennium bug, however you shift it alongside a bit.
DOUG. Let the longer term generations will cope with it!
DUCK. Completely.
After all, you are able to do that with GPS rollover, and that’s what a variety of software program does.
How have you learnt what beginning date to make use of? Nicely, the apparent strategy to do it’s to make use of the time, or the date, or the yr during which you compile the software program that’s presently working on the GPS gadget – as a result of that may by no means go backwards.
And so you are able to do a comparability that claims, “I don’t anticipate this software program to return into play earlier than, say, 2003. So, if ever I see a yr that’s earlier than 2003, I’ll simply assume I’m out of vary.”
And what you’re doing is you’re tacking some days, weeks, months, years from the start of a GPS 1024-week interval – roughly 20 years; 19 years, seven and a half months….
…you’re mainly taking some days and also you shifting them to the tip of the present kiloweekary interval.
And the suggestion is that which will have been what caught Honda out right here.
The explanation I’m guessing that’s the case is {that a} reader of The Register, which is a well-liked IT publication within the UK, commented there that he had a Honda CR-V that was affected by this, and each time he begins his automotive, the time jumps again to 01 January 2002, as if the clock simply doesn’t know what to do.
So, it’s selecting the beginning of the yr as a default. (However then, after all, as a result of the clock’s fed by GPS, you may’t set it manually.)
On this case, it seems as if it is aware of what the proper time is, but it surely doesn’t know what yr it’s, so it figures, “I’ll simply I’ll begin at midnight, kind of, plus or minus no matter time zone I feel you’re in.”
Apparently, this man discovered that his GPS thought it was Might 2002, nearly precisely 1024 weeks in the past, which is what made him suppose this smells like GPS rollover.
DOUG. Fascinating.
DUCK. And that’s the very best guess that I may give you as to how this occurred: that it’s attributable to one thing just like the Millennium bug, however associated to a limitation which was constructed into GPS, understandably, within the Nineteen Seventies, as a result of each bit counts when you must get it reliably by means of house.
So, who is aware of what occurred, Doug?
But it surely is a sign to any programmer that, once you’re writing code at this time, and also you suppose, “What’s the possibility that the code that I’m cranking out at this time will nonetheless be in use in 2042?”…
…the reply is *most likely* not, however very *probably* may very well be.
DOUG. You by no means know!
DUCK. And subsequently, the choices you make at this time actually may have an effect on those that far forward.
DOUG. “Please consider the youngsters,” what I imply?
DUCK. Precisely!
Because the millennium bug proved; as bugs like this show: 20 years is each a really very long time, but in addition fairly a short while, in the case of the longevity of laptop software program.
DOUG. Completely.
All proper, that’s an interesting story – we’ve obtained et some good feedback happening, so come and skim all about it: Honda vehicles in flashback to 2002 – “Can’t get you out of my head”.
And now I’ve obtained that earworm….
DUCK. You mentioned it! I don’t suppose I truly used these phrases.
I simply mentioned, [SINGS, FADING OUT GRADUALLY] “La la la, la la la la-la/La la la, la la…”
DOUG. We don’t prefer to disappoint right here, however sadly we’ve got no Apple bug…
DUCK. [ANXIOUS] I earmwormed myself!
DOUG. You’ve earwormed your self?
We’ve no Apple bug story this week, however we do have we will’t provide a Log4Shell story.
So perhaps that’s our new Apple-bubble story – we’ve obtained a few these.
DUCK. I’m hoping that Log4j will jolt that music out of my head as a result of I’ve genuinely earwormed myself, Doug, and I can’t actually complain, can I?
DOUG. No, sir!
DUCK. Aaaaargh.
All proper, so it’s not fairly Log4j yet again, but it surely’s an essential reminder.
As from final week’s podcast, we spoke about how the US public sector decreed, “The Evening Earlier than Christmas: thou shalt get this completed by then. Don’t go away it. Do it at this time. It’s not going to go away of its personal accord.”
Nicely, come the New Yr; come the Federal Commerce Fee – the FTC is mainly the US client rights organisation, and it has come out with fairly a fairly a punchy, boxy little reminder to companies that function in US jurisdictions.
Even should you’re the sufferer of a cybercrime, then should you may have prevented it by patching, and it was affordable to anticipate that you’d have completed so, you might also be liable your self.
They have been fairly punchy in what they mentioned, and the warning consists of these phrases, Doug: “The FTC intends to make use of its full authorized authority to pursue firms that fail to take affordable steps to guard client knowledge from publicity because of Log4j or comparable identified vulnerabilities sooner or later.”
DOUG. Whoa!
DUCK. It’s not simply Bare Safety saying, “Patch early, patch typically”!
It’s the FTC reminding you that sympathy solely goes to this point, and you could be each a sufferer and a committer of cybercrime on account of the identical purpose – i.e. not having patched.
It lets the crooks in, and we’ll really feel sorry for you for that.
But when it lets crooks in the place the place you may fairly have been anticipated to have stored them out, by taking the precautions that frankly everybody else was, then perhaps you’ll have to hold the can for a few of that.
DOUG. OK, so after they say “Log4j or comparable identified vulnerabilities sooner or later”, not too far after that, we we had the same vulnerability with this H2 bug.
DUCK. Sure, surprisingly just like Log4Shell.
And, in reality, discovered by researchers who have been wanting by means of Java code for comparable kinds of programming that led to the Log4Shell vulnerability within the first place.
This bug, CVE-2021-42392, was found by a provide chain administration firm referred to as JFrog.
They determined, “Hey, let’s go look by means of all of the Java code that may include comparable use of this JNDI factor” – this Java Naming and Listing Interface that turned out to be abusable within the Log4j bug.
And should you bear in mind JNDI, that’s the factor the place you truly say, “Hey, I need you to look this knowledge up. Oh, I haven’t obtained the information, however I’ll ship you a URL for some knowledge; in reality, I’ll ship you a URL for a program: run this system and see what that tells you.”
JFrog, I suppose, have been questioning what number of different packages have elements of their code the place this JNDI identify lookup performance may very well be used and maybe overused.
Sadly, they in a short time discovered one in a well-liked Java SQL database engine referred to as H2.
Now, I’ve to be trustworthy, Doug, I hadn’t heard of H2 earlier than.
DOUG. No, me neither.
DUCK. I’ve heard of MySQL, PostgreSQL, SQLite, all of the No-SQL database stuff.
However I’d by no means heard of H2 for a similar purpose I’d by no means actually heard of Log4j: its entire declare to fame was it was one thing that was compact sufficient that – in contrast to, say, MySQL or Microsoft SQL, the place you you run up a server and connect with it – hey, you may simply suck it into your software, have H2 as a part of your software.
DOUG. Oh, cool!
DUCK. It’s one other a type of issues the place purposes that you simply might need put in – they might have pulled this in, identical to Java apps may have pulled in Log4j.
The dangerous information is that the bug works in nearly precisely the identical manner because the Log4Shell vulnerability: you get this JNDI factor, and as a substitute of simply doing an area lookup, you say, “Hey, have you learnt what? For the lookup, here’s a URL; go and get this Java class file and run it.”
So it’s the identical sequence of occasions that results in the exploitability.
That’s the dangerous information.
The excellent news is that, so far as I can inform, the one life like manner that an attacker would have the ability to exploit that is if they might get in and modify the configuration file for this H2 part on one of many computer systems in your community.
In different phrases, it’s extra of an elevation of privilege or a lateral motion trick than it’s distant code execution.
Becausem though you might use it for distant code execution if the opening have been open, you’d should get native entry to be able to open up the entire for distant entry, if what I imply.
DOUG. Sure.
DUCK. In different phrases, you must break into the community to have the ability to break into the community.
However it’s nonetheless one thing you wish to patch, as a result of it’s a function that was there by mistake, identical to the Log4Shell drawback.
So, it’s nonetheless a bug with patching; it’s simply not fairly the distant code execution potential disaster that we noticed with Log4Shell.
DOUG. OK, we’ve obtained some recommendation.
If you’re you’ve obtained an app that’s working the H2 database engine, you may improve to model 2.0.206; or should you’re undecided, you may seek for cases of the H2 code in your community.
DUCK. Sure, that’s a bit of bit just like the Log4j drawback, isn’t it?
When folks stopped to consider it, they realised they really didn’t know what number of apps they’d that have been in Java to begin with; after which they didn’t know what number of of these had included Log4j.
Once they went wanting, they discovered, “Golly, there’s much more Java apps than we thought, and a variety of them simply occurred to have Log4j.”
Identical with this H2: it may very well be in an app act with out you even realising it.
DOUG. There’s that Invoice of Supplies once more – we’d like that Invoice of Supplies!
DUCK. Precisely!
So, such as you did with Log4j, the place you have been searching for log4j DASH no matter…
…right here you may search for recordsdata referred to as h2 DASH STAR DOT jar – that’s Java Archive.
When these recordsdata seem, should you’ve obtained any, they’ll most likely give you one thing like h2 DASH two DOT zero DOT some quantity or different DOT jar.
And such as you mentioned, Doug, what you’re searching for is 2.0.206 or later.
DOUG. OK, hop to it, everyone!
That known as Log4Shell-like safety gap present in widespread Java SQL database engine H2, on nakedsecurity.sophos.com.
DUCK. And don’t take it from us that you must hop to it. Take it from the FTC!
DOUG. Sure, significantly! [LAUGHS]
DUCK. I don’t wish to say they’re threatening folks, however they’re saying, “It issues.”
DOUG. They’re “strongly urging”.
And you’ll learn extra about that one on nakedsecurity.sophos.com: FTC threatens authorized motion over unpatched Log4j and different vulns.
And as we spherical out the present, it’s time for the Oh! No! of the week.

DOUG. It is perhaps, as a result of he begins by saying, “Again within the olden days…” [LAUGHTER]
I used to be the one telephone help tech for one of many ubiquitous PC clone homes that used to promote within the laptop magazines.
We had offered 200 computer systems to a software program firm, and the primary one went on to a VP of the corporate to check out whereas we constructed the remainder of the order.
The gross sales rep got here to me in a full panic, telling me that the machine, which I had examined earlier than it left the store, wouldn’t activate.
I referred to as the VP who mentioned there have been no lights on the machine in any respect.
I requested them to take a look at the again and see if the facility provide fan – the one fan in these days – was spinning.
He advised me to hold on – he needed to flip the sunshine on.
Wouldn’t it?
He had plugged it right into a switched outlet.
And Paul, I’m to know if this even is smart to you….
It ends by saying, “The gross sales rep purchased me lunch for saving his fee.”
Do you actually have a idea of the “switched outlet” in your neck of the woods?
DUCK. In truth, I feel that in each jurisdiction I’ve ever lived in my life…
…I’ve not encountered the phenomenon of an *unswitched* outlet.
DOUG. Oh, that’s proper, sure!
DUCK. For security causes, why not have a swap, so you may flip it off?
It’s notably related within the UK the place we use ring mains – if one outlet is reside, they’re all reside.
So we’ve got retailers which can be, as I perceive it, switched by regulation.
The bizarre factor that we’ve got – in two of the international locations I’ve lived in have the regulation – I don’t suppose you will have it within the US – that you simply’re not allowed mild switches inside the toilet.
DOUG. Fascinating.
DUCK. You both should have an everyday mild swap exterior the toilet, or – mostly within the UK – you will have a pull swap the place the swap is within the ceiling, and it’s operated by a string that doesn’t conduct electrical energy.
However you’re not allowed a swap – or an outlet – in a rest room.
DOUG. Fascinating!
