Remote code execution via Mediaserver.exe stack overflow
Published Apr 3, 2022 · Updated Aug 3, 2024
Out-of-bounds write in ALLMediaServer 1.6 allows remote attackers to execute arbitrary code via a long string sent to TCP port 888. Mediaserver.exe copies the overlong HTTP request data into a stack buffer without adequate bounds checking, overwriting the structured exception handler and redirecting execution. The service accepts the request without authentication; successful exploitation can compromise confidentiality, integrity, and availability, and public exploit implementations target x86 or WoW64 builds.
