Description
WM Downloader version 3.1.2.2 is vulnerable to a buffer overflow when processing a specially crafted .m3u playlist file. The application fails to properly validate input length, allowing an attacker to overwrite structured exception handler (SEH) records and execute arbitrary code. Exploitation occurs locally when a user opens the malicious file, and the payload executes with the privileges of the current user.

An exploit or proof of concept is public: anyone can try it against an unpatched system. The public collections list a Metasploit module for it. 3 references of the record are tagged as an exploit. CISA's SSVC rates its exploitation: a proof of concept is public.
