FortiBleed Is Still Biting, and Admins Are Getting Properly Screwed
Right, here’s the ugly mess: the FBI says attackers are still exploiting the FortiBleed bug against Fortinet FortiGate VPN devices, and if you’re one of the poor bastards running one of these things without fixing it, there’s a fair chance some scumbag has already rummaged through your session data and helped themselves.
FortiBleed, for those blissfully ignoring their patch notices, is a nasty information disclosure vulnerability in FortiOS SSL-VPN. In plain English: it can leak chunks of memory, including login sessions. Which means attackers may not even need your password if they can just nick your active session cookie and stroll right in like they own the bloody place.
According to the article, the FBI is warning that these attacks are ongoing, and in some cases the attackers aren’t just sneaking in quietly—they’re changing firewall configurations and locking legitimate admins out of the devices. Because apparently simple compromise wasn’t enough; they had to go the extra mile and be complete assholes about it.
The whole point is grimly simple: once the attackers hijack admin sessions, they can mess with settings, create persistence, and generally turn your security appliance into their security appliance. That’s the sort of irony that would be funny if it weren’t such a colossal shitshow.
The FBI and Fortinet’s advice is the same boring thing admins should have bloody done already: patch the devices, upgrade to a fixed version, review configs, check for unauthorized changes, invalidate sessions, and assume compromise if the box was exposed and unpatched. If you’re still sitting there thinking, “I’ll get to it next week,” congratulations, you may as well hand the keys to the attackers and save everyone the trouble.
They’re also warning organizations to look for signs of session hijacking and admin account abuse. So yes, you get the usual delightful post-incident scavenger hunt: comb through logs, verify accounts, rotate credentials, and work out whether the random config changes were made by your team or some hostile little goblin halfway across the planet.
Bottom line: FortiBleed isn’t old news just because people are tired of hearing about it. It’s still being exploited, admins are still getting locked out, and unpatched FortiGate VPN systems are still basically hanging a giant sign out front saying, “Please rob me, I’m incompetent.” Patch your shit.
This reminds me of the time some genius ignored firmware updates for months, then acted shocked—shocked—when they got booted off their own firewall and called it “suspicious behavior.” No, sunshine, that’s what happens when you run critical infrastructure like a fucking garden shed with Wi-Fi. Anyway, patch first, whine later.
