CISA Waves the Bloody Alarm: Patch OpenSSH and GPUStack Before the Idiots Burn the Place Down

Right, here’s the short version for the sleep-deprived, ticket-chasing, soul-dead sysadmins in the back: CISA has flagged two actively exploited vulnerabilities, one in OpenSSH and one in GPUStack, and they’re basically telling everyone to stop arsing about and patch the damn things already.

The OpenSSH issue, tracked as CVE-2024-6387, is the nasty one people have been calling regreSSHion, because apparently naming vulnerabilities like rejected energy drinks is still a thing. It’s a signal handler race condition in the OpenSSH server that can lead to unauthenticated remote code execution as root on glibc-based Linux systems. Yes, root. As in, “congratulations, the attacker now owns your box and probably your weekend too.”

The bug affects OpenSSH versions from 8.5p1 up to but not including 9.8p1. The fix is to upgrade to 9.8p1 or whatever patched version your vendor has shoved out. If you’re sitting there thinking, “Maybe we’ll schedule that for next quarter,” then you deserve the incoming shitstorm.

The second mess involves GPUStack, tracked as CVE-2024-37032. This one is an authentication bypass vulnerability that can let attackers gain unauthorized access to vulnerable instances. Translation: some enterprising little bastard can stroll right in because the front door is apparently made of damp cardboard. If you’re using GPUStack and haven’t updated, you might as well hang a sign on the server saying, “Please loot responsibly.”

CISA added both flaws to its Known Exploited Vulnerabilities (KEV) catalog, which is government-speak for: “This isn’t theoretical anymore, you useless muppets. Bad actors are already exploiting this crap.” And when CISA says patch quickly, they don’t mean after three change advisory meetings, two pointless PowerPoints, and one manager asking if the risk can be “accepted.” They mean now.

For federal agencies, the order is simple: remediate by the deadline CISA set. For everyone else with more than three neurons to rub together, the advice is exactly the same. Patch OpenSSH. Patch GPUStack. Restrict exposure where possible. Check for indicators of compromise. And for the love of all that is broken and underfunded, don’t leave SSH flapping around on internet-facing systems without verifying the version.

The article’s basic message is brutally simple: these vulnerabilities are already being abused in the wild, and if your environment is exposed, you need to move before some fucker does it for you. This is not the time for “careful evaluation,” “roadmap alignment,” or whatever other corporate horseshit gets wheeled out when no one wants to reboot a production server.

I once watched a bloke ignore an SSH patch because he “didn’t want to interrupt workloads,” then spent 19 straight hours rebuilding compromised systems while swearing at a KVM console and crying into a vending machine coffee. Moral of the story: patch early, or suffer spectacularly and deserve every miserable second of it.
