Exploitation Summary

EIP tracks 3 public exploits for CVE-2011-10025. PoCs published by Metasploit, Brandon Murphy, Brandon Murphy, sinn3r, including Metasploit module exploits/windows/fileformat/subtitle_processor_m3u_bof.

AI-analyzed exploit summary This Metasploit module exploits a Unicode SEH buffer overflow in Subtitle Processor 7.7.1 via a maliciously crafted .M3U file, achieving arbitrary code execution on Windows XP SP3 and Vista SP0.

Description

Subtitle Processor 7.7.1 contains a buffer overflow vulnerability in its .m3u file parser. When a crafted playlist file is opened, the application converts input to Unicode and copies it to a fixed-size stack buffer without proper bounds checking. This allows an attacker to overwrite the Structured Exception Handler (SEH) and execute arbitrary code.
