[hlds] New TF2 server exploit?

2012-12-24 Thread Ross Bemrose
I just saw this on Reddit: 
http://www.reddit.com/r/tf2/comments/15dacx/psamajor_mann_vs_machine_exploit/


Apparently it's possible for clients to alter tournament settings that 
they shouldn't be able to change in MvM mode.

I don't understand how a client can change a server-side convar, I thought
they could only execute FCVAR_GAMEDLL commands? Sounds like a very strange
bug on Valve's part.



Kind regards,
Saul Rennison

 Confirmed, it has something to do with these 2 vars:

 mp_tournament_allow_non_admin_**restart
 and
 mp_tournament_restart

 Tried on my own server, and I can toggle the non_admin_restart back and
 forth, even if I don't have admin privs in the first place.  But the real
 kicker is the mp_tournament_restart.  Just as the reddit thread states,
 when exec'd during setup phase, everyone gets unreadied and timer resets.
  If exec'd during a wave, when a bot with the bomb gets killed + drops it,
 no other bot can pick it up for the rest of the wave.

Re: [hlds] New TF2 server exploit?

2012-12-24 Thread scott biszmaier
looks like a simple solution would be to set up overrides with sourcemod. set 
the known cvars
to the root override, wonder if this would work or not?
