Cisco Finally Patches Its “Oh Crap, We Forgot That” Zero-Day – About Bloody Time

So, Cisco – yes, that multi-billion-dollar networking overlord – finally got off its collective arse and patched a zero-day vulnerability in its AsyncOS software that had been getting pounded since freakin’ November. That’s right, for months some sneaky bastards were poking around their Security Appliances and Email Security Gateway gear, apparently having a field day while Cisco was too busy rearranging deck chairs on the Titanic to notice.

This shiny little screw-up (officially tracked as CVE-2024-20395) let attackers bypass authentication on web interfaces like ESA, SMA, and WSA – as in, “no password required, come right in!” Cisco says there’s “no evidence” the clowns used it for wider mayhem. Oh yeah, sure, and I totally believe the fox saying he didn’t eat the chickens.

Now, after months of being slapped around by reality, Cisco finally burped out fixed versions. But only if you’re on the stuff they still support — because if your box is old, congrats, you can go screw yourself or buy a new one. Classic corporate upsell disguised as “security patch.”

Apparently, the exploit chain had been seen in the wild targeting appliances since late last year, and Cisco only managed to publicly admit it in May after third parties made it too obvious to ignore. Brilliant work there, lads. Truly inspiring what can happen when you manage to stop face-planting into your Slack channels long enough to actually read your own security reports.

If you’re running any Cisco Email or Web Security Appliance, update it now, reboot it, sacrifice a goat to the network gods, and hope this is the last time Cisco leaves the bloody door unlocked for half a fiscal quarter.

Sign-off: Reminds me of that time a sysadmin swore their firewall was “locked down” – until I showed them I could telnet into it without credentials from the bloody coffee machine. Some people should come with a warning label.
