Oh, For F\*ck’s Sake. Citrix is Screwed… *Again*.

Right, listen up you lot. Apparently, Citrix – yes, that Citrix, the kings of perpetually vulnerable software – are getting hammered by another zero-day vulnerability. CVE-2023-19043, to be precise. It’s in their NetScaler ADC and Gateway appliances. Basically, if you’re running versions before 12.1.6.89, 12.1.5.135, or 13.0.77.10, you’re a sitting duck.

What does it *do*? Oh, just lets attackers bypass authentication and do whatever the hell they want. Remote code execution, data theft, the whole nine yards. And guess what? It’s actively being exploited. Like, right now. The Lazarus Group (North Korean state-sponsored assholes) are already poking around.

Citrix has a patch, naturally. But you know how that goes. Everyone will wait until the last possible second when their systems are already compromised before applying it. They’re offering some lame workaround stuff too, but honestly? Just patch the damn things. And if you haven’t updated in… well, ever? You deserve whatever you get.

Seriously, this is getting ridiculous. I swear, maintaining Citrix infrastructure is a full-time job just keeping it from falling apart. Don’t come crying to me when your data gets ransomed.

Anecdote: I once had to deal with a company running an unpatched Citrix farm from 2008. 2008! They were shocked when it got pwned by a script kiddie using tools that haven’t been updated since the Clinton administration. Shocked, I tell you! Some people just *want* to be hacked, honestly.
