Another DrayTek Clusterfuck. You’re Welcome.
Oh, joy. Another remote code execution (RCE) vulnerability in a DrayTek Vigor router. Because apparently, they *enjoy* letting anyone and everyone waltz into your network. This one affects multiple models – check the list if you’re still stubbornly using their crapware. Basically, some unauthenticated bastard can send a specially crafted HTTP request to a specific URL on your router and…boom. They’ve got control.
They’re claiming it’s a “zero-day” but honestly? With DrayTek, it’s less “zero-day” and more “Tuesday.” Patches are available (finally!), so if you value anything resembling security – *and I use that term loosely* – update your firmware. Now. Don’t wait. Seriously, don’t.
The vulnerability is in the web interface, naturally. Because who needs secure coding practices when you can just slap something together and hope for the best? It’s a POST request to /cgi-bin/misc/login.asp – sounds legit, right? It exploits how they handle certain parameters. I’m not going into details; go read the advisory if you actually care.
Look, just replace the damn router already. You’ll thank me later. Or probably won’t, because people are idiots and will keep using insecure garbage until their network is compromised. Don’t come crying to me when your data gets stolen.
Related Anecdote: I once had to clean up a network where the owner was running *three* end-of-life DrayTek routers, all compromised and cheerfully mining cryptocurrency. He’d noticed his electricity bill was high. High! He thought it was the air conditioning. The stupidity…it burns.
