|
||
|
|
This module exploits a stack-based buffer overflow in GTA SA-MP Server.
|
||
|
|
This buffer overflow occurs when the application attempts to open a malformed
|
||
|
|
server.cfg file. To exploit this vulnerability, an attacker must send the
|
||
|
|
victim a server.cfg file and have them run samp-server.exe.
