SELECT shell FROM postgres: Digging up a 20-year-old bug for ZeroDay.Cloud by @pspaul95.bsky.social and Moritz Sanft
This was pretty fun to exploit! Even though I didn't manage to pwn the version used for Pwn2Own Berlin, I still learned a ton about LLMs. Maybe I can get my revenge in future competitions 🤞
Pwning PostgreSQL was quite fun, excited to share our research at OffensiveCon!

A fun gadget I found recently! The .NET JIT compiler makes sure there are no rwx pages by using a memfd, but that turns file writes into straight shellcode execution 🐚
