CISA Waves the Bloody Patch Stick at Cisco, Citrix, and Fortinet Again

Right, here’s the gist, because apparently some vendors still need a government agency to walk in, point at the flaming server rack, and say, “Yes, that’s bad, you useless bastards.” CISA has added a fresh batch of actively exploited vulnerabilities affecting Cisco, Citrix, and Fortinet to its Known Exploited Vulnerabilities catalog, which is bureaucrat-speak for “patch this shit now before someone steals your network and your dignity.”

The agency has slapped U.S. federal civilian agencies with a deadline of September 12 to fix the mess. That means admins across government are now doing the traditional security dance: panic, change window requests, emergency patching, and a lot of swearing at vendors who somehow keep shipping expensive enterprise gear with gaping holes in it.

The big point, in case subtlety isn’t your thing, is that these flaws are already being exploited in the wild. Not “might be exploited,” not “theoretical,” not “under certain lab conditions with a unicorn and a packet sniffer.” Exploited. As in attackers are using them now. Which means if you’re sitting there waiting for next quarter’s maintenance cycle, you may as well just email your credentials directly to the nearest ransomware crew and save everyone some time.

Cisco, Citrix, and Fortinet are all involved, which is just wonderful. Three pillars of enterprise infrastructure, and somehow all roads still lead to “critical patch immediately.” The article’s main takeaway is brutally simple: if you run this kit, stop pretending your change control process is sacred scripture and get the damned fixes deployed. CISA doesn’t issue these deadlines for fun, and attackers sure as hell aren’t waiting for your CAB meeting.

This is the usual security farce: vendors release advisories, CISA updates the KEV catalog, defenders scramble, and somewhere an overpaid executive asks whether this can wait until after the weekend because it might “impact operations.” Yes, genius, being fully compromised tends to impact operations too. Possibly more than a reboot.

So the summary is this: critical network and security products from Cisco, Citrix, and Fortinet have known exploited flaws, CISA has formally raised the alarm, and federal agencies have until September 12 to patch them. If you’re outside government, congratulations, the attackers still won’t spare your sorry environment, so patch your shit anyway.

Anecdote time: years ago, I watched an admin ignore an “urgent” firewall update because he didn’t want to interrupt lunch. By dinner, the box was acting like a public bus station for every scumbag on the internet, and he spent the night explaining to management why “deferred maintenance” had turned into “incident response.” Moral of the story: patch first, eat later, and stop trusting enterprise vendors to save your arse.
