Secure Your Systems: Urgent Update for Rockwell Automation Products to Thwart High-Risk Vulnerability!

Rockwell Automation’s latest hiccup? A CVSS v4 score of 9.2 for a pesky vulnerability causing major product amnesia—manual reboot required. #MajorNonrecoverableFault

Hot Take:

Looks like Rockwell Automation’s got a bit of a rocky situation! Their programmable logic controllers have developed a taste for the dramatic with a ‘major nonrecoverable fault’. That’s tech lingo for ‘I need a siesta, don’t bother me.’ If your happy little factory relies on these gizmos, you might want to hold off on that coffee break and get updating, or you’ll be playing hide and seek with your production metrics!

Key Points:

  • Risk of ‘major nonrecoverable fault’—sounds like my last relationship.
  • ControlLogix, GuardLogix, CompactLogix, and the party animal 1756-EN4TR are the affected rock stars.
  • It’s raining CVSS scores! A 9.2 on the new scale, because why not go big?
  • Update-palooza: Rockwell Automation’s serving fresh updates to fend off the cyber boogeymen.
  • CISA’s advice: Hide your devices behind firewalls and cozy up with VPNs like it’s 2024.
Title: Rockwell Automation ControlLogix and GaurdLogix Vulnerable to Major Nonrecoverable Fault Due to Invalid Header Value
Cve id: CVE-2024-3493
Cve state: PUBLISHED
Cve assigner short name: Rockwell
Cve date updated: 04/15/2024
Cve description: A specific malformed fragmented packet type (fragmented packets may be generated automatically by devices that send large amounts of data) can cause a major nonrecoverable fault (MNRF) Rockwell Automation's ControlLogix 5580, Guard Logix 5580, CompactLogix 5380, and 1756-EN4TR. If exploited, the affected product will become unavailable and require a manual restart to recover it. Additionally, an MNRF could result in a loss of view and/or control of connected devices.

The Problem Child: Improper Input Validation

Turns out someone didn't teach their packets to behave properly, and now they're throwing tantrums in the form of 'major nonrecoverable faults'. To the non-nerd eye, this just means your fancy controllers might take an unplanned vacation, and good luck getting them back to work without a manual reboot. And while they're sipping margaritas on the beach, guess who's not watching the manufacturing line?

Affected Products: The Usual Suspects

If you've got any of the ControlLogix 5580, GuardLogix 5580, CompactLogix 5380, or the 1756-EN4TR hardware lounging around, you'll want to whisper sweet nothings of firmware updates into their ears. They're all dressed up in version V35.011, which is apparently last season's look.

CVSS: Now in 4K Resolution

Everyone loves a good score, and a CVSS v4 of 9.2 is like scoring a hat-trick in the cybersecurity champions league. It's a number that makes you want to sit up, pay attention, and maybe even panic a little if you're into that sort of thing. But hey, no pressure.

Geography & Background: Worldwide Woes

This isn't just a local garage band going off-tune; it's a worldwide rock concert of potential chaos. With critical infrastructure sectors in the mix, it's less 'We Will Rock You' and more 'We Could Lock You...out of your systems.'

The Fix Is In: Update Fiesta!

Rockwell Automation didn't just throw their hands up and walk away. They're rolling out the updates like a red carpet. If you're using any of the hit list controllers, you've got VIP access to versions V35.013 or V36.011, and for the 1756-EN4TR, there's the exclusive V6.001. Get updating, or get left behind.

CISA's Two Cents: Better Safe Than Sorry

The cybersecurity VIPs at CISA are singing 'Protect Ya Neck'. They're all about minimizing exposure, isolating devices like they're introverts at a party, and using VPNs like they're going out of style (which, let's be honest, they never will). And just in case you're the kind who skips the terms and conditions, they've thrown in a reminder to actually assess risks before going all gung-ho with the mitigations.

Remember, no one's seen this vulnerability in the wild yet, but in the world of cybersecurity, it's like Bigfoot—just because you haven't seen it, doesn't mean it's not out there, waiting to crash your industrial control system party. So, lace up your digital sneakers and get to it!
