Source Engine Remote Code Execution on Kill

Recommended Posts

I saw this the other day and thought people might get a kick out of it.



Obviously, you'd need to own the server or I guess be able to get the modified ragdoll files out onto other servers but I think the idea of having to kill a player to execute an exploit is hilarous.

Imagining a game where if you wreck someone 1v1 you get control of their box. A nerdy version of racing for pink slips

Becoming a professional TF2 player to steal credit card information. It is an ingenious plan!

I wonder if a fuzzer could have found this.

Potentially. The method doesn't seem to rely on any complex state, so it shouldn't be too difficult to fuzz, anyway. It's so simple though, you'd probably be able to figure it out manually pretty quickly once you'd picked it out as something worth investigating anyway.

Related: all the GoldSrc games got updated recently due to a vulnerabiltiy someone found in the BSP parsing code, via fuzzing: https://hernan.de/blog/2017/07/07/lock-and-load-exploiting-counter-strike-via-bsp-map-files/
