BeyondTrust Drops a Fresh Bag of Critical Security Shit

Right, here we go. BeyondTrust has very helpfully announced a pair of nasty, critical vulnerabilities in its Privileged Remote Access and Remote Support software, because apparently letting attackers stroll into remote access platforms wasn’t already enough of a bastard problem. The bugs are tracked as CVE-2025-5309 and CVE-2025-5310, and yes, they’re the sort of flaws that make admins spit coffee across the server room and mutter “for fuck’s sake” at 7:30 in the morning.

The first flaw is an authentication bypass in the Remote Support and PRA products. Translation: under the wrong conditions, some malicious git may be able to skip past login protections like the whole bloody system is running on trust and fairy dust. The second issue is a command injection bug in Privileged Remote Access, which is exactly the kind of sentence that should make anyone responsible for production systems start sweating through their shirt. Command injection in remote access software? Brilliant. What could possibly go wrong, other than everything.

BeyondTrust says these vulnerabilities affect PRA and Remote Support on-premises versions 24.3.x and 25.1.x. They’ve released patched versions, so the fix is, in theory, straightforward: stop faffing about and update the damned things. If you’re running vulnerable builds and still thinking “we’ll get to it next maintenance window,” then congratulations, you’re volunteering your infrastructure to the internet’s least charming criminals.

The company also said it found the issues during internal code reviews and testing, which is nice, I suppose. Better they found the holes before every ransomware goblin on Earth did. At the time of reporting, there’s no evidence of active exploitation, but that’s never a reason to sit on your arse and do nothing. “Not exploited yet” is security-speak for “you’ve still got a few minutes before this becomes someone else’s very bad day.”

So the summary for the terminally busy: if you use BeyondTrust PRA or Remote Support, check your version, patch the bloody software, and quit pretending critical remote access vulnerabilities are the kind of thing that can wait until after lunch. Because when authentication bypass and command injection show up in the same advisory, the correct response is not calm reflection. It’s “holy shit, patch it now.”

This all reminds me of a place where management ignored a critical remote access flaw because applying updates would “disrupt operations.” A week later, operations were indeed disrupted — by a total outage, three consultants charging by the hour, and one sweating executive asking why the backups were on the same compromised network. Funny how nobody worries about maintenance windows after the entire bloody house is on fire.
