Total Video Player 1.20 M3U File Local Stack Buffer Overflow Exploit
==================================================================== Total Video Player 1.20 M3U File Local Stack Buffer Overflow Exploit ==================================================================== /*0day Total Video Player V1.20 .M3u File Local Stack Buffer Overflow This exploit spawns Calc.exe or binds a port and spawns a shell and tested on Windows Xp sp 2. I got the ideea to look in a prior version of TVP and surprinse vuln to ,just as V1.30. When parsing a crafted .m3u file stack gets corrupted,due a long string,and causes a stack overflow.We get control of the EBP and EIP registers.The ESP register points exactly after the retaddress position. [corrupted stack] [EIP->points here][ESP->points here] So do a jmp back and a JMP ESP and it points to a specific part of the stack that I want.Credits to finding this bug && sploit go to fl0 fl0w. Vendor not informed yet.
