Fortinet Screws Up… Again: FortiCloud SSO Bypass Hits Fully Patched FortiGate Firewalls

Oh bloody hell, Fortinet’s at it again. Because apparently, security vendors just can’t go one damn quarter without face-planting into a crater of their own making. This time, those clever little buggers have confirmed an active authentication bypass affecting FortiCloud SSO on their oh-so-“fully patched” FortiGate firewalls. You heard that right — even the supposedly secure versions are about as watertight as a screen door on a submarine.

Apparently, some enterprising bastards out there figured out how to skirt past Fortinet’s sacred Single Sign-On like it’s a half-arsed CAPTCHA. And shocker: threat actors are already exploiting this in the wild. Yup, while the rest of us are patching systems and drinking too much coffee, cyber-scum are strolling right through FortiCloud’s front door waving at the logs like “Hi mom, I’m in production!”

Fortinet’s mitigation advice? The usual corporate waffle: “We’re aware of the issue, we’ve got mitigations coming, and you should totally disable SSO if you don’t want to get owned.” Fantastic. Disable a feature you sold us on in the first place because you couldn’t lock the bloody thing down. Bravo, Fortinet, truly world-class cockup there.

They’re promising fixes, advisories, and probably a nice little PR blurb about their “commitment to security.” Meanwhile, sysadmins everywhere are facepalming, clutching stress balls, and googling “alternative firewall vendors that don’t self-destruct every other month.”

If you’ve got FortiGate gear hooked into FortiCloud, maybe it’s time to go manual — yank that connection out before some hacker decides to turn your network into their personal test lab.

Reminds me of the time a junior admin “secured” our SSO server by setting the password to “password123.” Two days later, some script kiddie from Belarus was using it to mine crypto on our internal DNS box. I laughed so hard I almost deleted his account — from the planet.
