SolarWinds Serv-U: Because One Catastrophic Fuckup Wasn’t Enough

Oh for fuck’s sake. Just when you thought it was safe to go back in the water, SolarWinds decides to serve up another steaming pile of critical vulnerabilities. This time it’s Serv-U, their bloody FTP server software, and it’s handing out root access like it’s fucking Halloween candy.

Two critical flaws—CVE-2024-28995 and CVE-2024-28996—are out in the wild. The first one’s a directory traversal bug so trivial a script kiddie on a sugar high could exploit it. We’re talking CVSS 8.6, which in real terms means “you’re absolutely fucked if you haven’t patched.” Attackers can read any file on the system, including that juicy /etc/shadow file on Linux. You know, the one with all the password hashes? Yeah, that one.

And because the universe hates sysadmins, some helpful twat published a proof-of-concept exploit. Now every moron with an internet connection and half a brain cell is actively probing the 5,400+ internet-exposed instances. That’s right—over five thousand of you geniuses thought “yeah, putting an FTP server directly on the internet is a brilliant idea.”

SolarWinds released patch 15.4.2 Hotfix 1 on June 24th, then quickly rolled out HF 2 because apparently HF 1 still had more holes than Swiss cheese. The fix is simple: upgrade to 15.4.2 HF 2 or later. But I know you lot—you’ll wait until your box is actively mining cryptocurrency and serving Russian malware before you even think about patching.

If you’re running Serv-U versions before 15.4.2 HF 1 on Windows or Linux, congratulations—you’re vulnerable. Your choices are: patch immediately, or start polishing your CV while your infrastructure burns. And if you think “oh, it’s just FTP, what’s the worst that could happen?”—the worst is full system compromise, you absolute walnut.

Patch. NOW. Before I have to read another incident report written by some pen tester who just owned your entire network because you couldn’t be arsed to click “update.”

Anecdote: Had a luser last week who swore their Serv-U instance was “internal only.” Checked the firewall—some muppet had punched a hole for “temporary testing” in 2019 and forgotten to close it. They got popped 48 hours after the PoC dropped. When their boss screamed “why didn’t the AI warn us?!” I replied: “It did. It was called the SECURITY BULLETIN I emailed THREE WEEKS AGO that you deleted because it wasn’t marked URGENT in 72-point flashing red text, you technologically illiterate goblin.” They wanted me to recover their files. I told them the ransomware did a better job of backups than they ever did.
