Summary

Janus WebRTC Server through 1.4.3 contains a path traversal vulnerability in the Record&Play plugin that allows unauthenticated attackers to write files outside recordings_path via the record request filename. Attackers can supply filenames with path separators to create or truncate files ending in -audio.mjr, -video.mjr or -data.mjr anywhere the Janus process can write outside protected folders.

Risk Assessment

An attacker can overwrite or create files in any location writable by the Janus process, potentially leading to data corruption, configuration overwrite, or code execution.

Recommendation

Upgrade Janus WebRTC Server beyond version 1.4.3 or restrict the Janus process write permissions and validate filenames in record requests.
