Hi all,
recently i discovered some new exploit in gameserver (i am not sure if new or not but for me yea!!)
1) many invites
How its done : ask many players to add you friend at same time then at some point the gameserver will crash
solution : i thought at first to limit the invite times but i failed then i made invite times 1 and limited the timeout to 3 seconds that helped to solve it !!
notes : that work with all invites (Trade - Disc - etc) but i haven't tried it on others just on friend but someone told me it work on all !!
2) walls
How its done : get your character and go cave on walls there, there is a free space that you cant cross at some point the abuser managed to crash game using that space giving the gameserver wrong info as that area not allowed to cross-through it
solution : i found that removing the not allowed cross was the best practice specially can be done server sided using yamii tool (Map Editor)
3) system chat
this one i am not sure how its done but i thought to reduce the local chat and other chat cooldown could solve it and until now i think its good
at the end i managed to get all those exploit ways at less that all i know maybe someone out there got other exploit ways i wonder too and i am not happy about that but at less we can solve what possible so i hope people participate on fixing and share their discovers !!
Thanks in advance!
