I found a zero day in a security vendor's firewall software that allows you to remotely crash the entire system by sending it a single malicious packet.

Any idea on the root cause? Is it potentially an RCE?

@malwaretech Ah, the joys of "security" software.

@malwaretech You should have waited till Friday. That's the Vulnerability Disclosure Day, isn't it?

@malwaretech reminds me of the 1990s (?) dirt-simple exploit whereby you could crash a Windows machine merely by sending it any OOB packet. Yes, I tried it and it worked. I later saw code for it in an exhibit of various exploits at Madrid's Reina Sofia art museum. Cool exhibit.

@malwaretech I wonder how much more difficult it is now to report vulnerabilities now that everyone is using “AI” to generate so much crap. -

@jerry is right again... https://www.youtube.com/shorts/IlptuY-0qpA #ThoughtLeader #Cyber@alister @malwaretech @jerry you need seven layers of firewall just like you need seven proxies duh.

@malwaretech Oh, but before I go crazy here, does it manage to log the source of the packet before crashing?
