Fortinet FortiWeb flaw with public PoC exploited to create admin users

FortiWeb’s Latest Dumpster Fire – Because Apparently Security Is Optional Now

Well, here we go again. Fortinet, the poster child for “What could possibly go wrong?”, has managed to cock up another security product. This time it’s FortiWeb, their fancy-schmancy web application firewall that’s supposed to keep people safe. Except—surprise, surprise—it’s got a massive bloody hole in it that lets any half-baked script kiddie become an admin faster than you can say “patch management failure.”

So what’s the deal? Turns out there’s a critical authentication bypass vulnerability — CVE-2024-21762 — that’s being *actively exploited* in the wild. Some clever bastard figured out how to use a public proof-of-concept exploit to waltz right past the login system and spin up their own admin accounts like they own the place. Because who doesn’t love giving the Internet keys to the kingdom?

Hackers, researchers, and probably your bloody neighbor’s teenager are all having a field day with publicly exposed FortiWeb interfaces still running unpatched versions. Threat actors are using it to create new admin users, grab sensitive data, and generally cause chaos while IT teams are too busy writing “urgent patch requests” that nobody reads. Fortinet—because of course they did—released patches months ago for versions 7.0.0 through 7.0.2, and for anyone not living under a damn rock, they’ve been screaming “patch your box!” ever since. But did everyone listen? Hell no.

Now the exploit is running loose in the wild, cybercriminals are chaining it with other nasties, and organizations are scrambling around like headless chickens trying to plug the hole after the barn door’s already been kicked wide open. Delightful. Really shows how much “proactivity” the industry has, doesn’t it?

TL;DR: Patch your bloody FortiWeb appliances now or prepare for random assholes to make themselves admin while you’re still trying to finish your coffee. Because yes, the Internet hates you, and yes, it’s your own damn fault if you’re still running outdated firmware.

Reminds me of the time a sysadmin colleague ignored firmware updates for six months because “nothing bad’s happened yet.” He said that right before the network got ransomwared so hard we had to rebuild half the servers from scratch. Some lessons you just have to learn with fire.
