CISA Waves the Bloody Red Flag Over Two Actively Exploited Critical Flaws

Right, gather round, because the clowns are on fire again. CISA has shoved two more bugs into its Known Exploited Vulnerabilities catalog, which is bureaucrat-speak for: “Oi, these bastards are being abused in the wild right fucking now, so patch your shit.” The two victims this time are Collabora Online and Arista VeloCloud, because apparently vendors still enjoy shipping expensive software with surprise attack surfaces baked in.

First up: Collabora Online. The flaw is nasty enough that attackers can exploit it remotely, which is exactly the kind of sentence that makes sysadmins reach for whisky before lunch. If you’re running the vulnerable versions and haven’t patched yet, congratulations, you may as well have left the server room door open with a sign saying, “Come in and wreck the place.” CISA added it because criminals are already taking advantage of it, not because they fancied adding more paperwork to the pile.

Then there’s Arista VeloCloud, which also earned itself a lovely spot on the KEV list. Same miserable pattern: critical flaw, active exploitation, urgent remediation, and a bunch of organizations suddenly pretending they were absolutely going to patch this week anyway. Sure you were. This bug affects networking infrastructure, which is especially fun, because when network gear gets owned, the blast radius can turn from “mild inconvenience” to “total operational clusterfuck” in record time.

The important bit, in case anyone in management is still asking whether this is “really urgent,” is that CISA doesn’t add things to KEV for a laugh. These entries mean exploitation has been observed in the real world. Not theoretical. Not hypothetical. Not some researcher waving a slide deck around at a conference. Real attackers are poking real holes in real systems, and if your environment still has these vulnerable products exposed, you’re basically volunteering to be the next cautionary tale.

So the summary is simple enough even for the committee types: identify affected Collabora Online and Arista VeloCloud instances, patch the damn things immediately, and check for signs of compromise. If you’re in a federal agency, you’ve got deadlines because CISA says so. If you’re not, you’ve still got the same threat, just without the luxury of pretending compliance paperwork counts as security.

And while you’re at it, maybe stop treating critical patching like some optional spa treatment for servers. Asset inventory, exposure management, log review, internet-facing service checks, emergency change procedures — all that boring crap matters, because the alternative is discovering your “digital transformation” now includes ransomware and a very angry incident response bill.

I once watched an admin ignore an urgent firewall update because he said he wanted to “wait for stability.” Three days later the box got popped, the VPN fell over, and suddenly everyone was holding emergency meetings while he stared at the floor like a guilty Labrador. Moral of the story: patch first, make excuses later.
