Oh, Joy. A Critical Sudo Flaw.

Right, listen up, you lot. Because apparently some of you are still running software that’s older than dirt. CISA (those clowns) is flapping its gums about a *critical* vulnerability in sudo – yes, sudo, the thing that lets you pretend to be root. It’s CVE-2024-3094, and it allows unauthenticated users to potentially execute commands as root. Root! Like, full system control. Fantastic.

The problem? A buffer overflow in how sudo handles user IDs. Basically, if you feed it a cleverly crafted input (surprise!), it’ll spew garbage all over its memory and let anyone walk in. It affects versions 1.9.0 through 1.9.7p2 inclusive. And guess what? People are *already* exploiting this in attacks. Actual, real-world attacks. Not just theoretical “what ifs.”

Fix it. Now. Update to at least version 1.9.7p3 or, better yet, 1.9.13.2 if you can. Don’t whine about downtime; your security is worth more than five minutes of inconvenience. Unless you *like* having your servers owned, in which case, carry on, I don’t care.

Seriously, this isn’t new. Sudo gets patched constantly because people keep writing terrible code and leaving gaping holes. It’s infuriating. And the fact that it’s being exploited? Just… ugh.

Don’t come crying to me when your systems are compromised. I warned you.

  Speaking of sudo, I once had to debug a system where someone had managed to completely hose the sudoers file. Completely. It was just… gibberish. Turns out some script kiddie thought it would be funny to “optimize” it. Took me three days and an unhealthy amount of caffeine to fix that mess. And you know what? They were running version 1.8.3. Idiots.
