CISA Adds Another Flaming Dumpster Fire of a Vulnerability to Its Shiny List

Oh bloody fantastic — CISA just announced that some clown left an actively exploited XSS bug (that’s CVE-2021-26829, for the masochistically curious) hanging wide open in OpenPLC’s ScadaBR system. Translation: Industrial control software that actually runs important crap like power grids and factories now has a gaping digital arsehole through which attackers can waltz right in. Bravo, humanity, bravo.

Apparently, this isn’t a fresh screw-up, but one of those “we’ll fix it later” messes everyone forgot about until hackers started shaking it like a piggy bank full of zero-days. So now, because patching is apparently HARD FUCKING WORK, it’s “actively exploited,” which means some bored script kiddies are already poking at industrial systems for giggles, or profit, or just to watch the world burn.

CISA, in its infinite wisdom, has added this gem to its Known Exploited Vulnerabilities (KEV) list — basically the list of “Oh Look, It’s On Fire” vulnerabilities that sysadmins are supposed to fix before their servers start spitting digital blood. The agency is waving its arms and shouting at federal agencies to patch this thing before their PLCs decide to become electronic paperweights. And yes, that means by the next due date, or someone’s getting chewed out in a government memo. Riveting stuff.

Long story short: if you’re running OpenPLC ScadaBR and haven’t patched this ancient turd, you might as well hand out administrator keys and a welcome mat that says “Hack Me Harder.”

Related anecdote: Reminds me of the time I told a user to stop clicking random “update flash player” pop-ups. He ignored me, got malware that sent 43,000 spam emails in ten minutes, and then complained that his Outlook crashed. I told him it was probably a “known exploited vulnerability” — between his ears.

Stay patched or stay fucked.
