gameserver Gameserver crash

[Fisal Moha 21]

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!

You can drop gameserver.exe from:

1 - WPE
2 - cha_timer overloaded "Old game files"

3 - bad configuration Gameserver.cfg "Entity: Impact of memory occupation"

4 - Many maps open on the same GameServer
5 - Overloading in the LOGS folder
