Short explanation
Prior to version 8.1.0, AVideo-Encoder contains an unauthenticated command execution vulnerability in its live-streaming endpoint, allowing remote attackers to execute arbitrary operating-system commands.
This flaw allows remote attackers to gain control over the system and compromise sensitive credentials without requiring legitimate authentication.
What should be done?
- Update software to version 8.1.0 or later
- Follow official vendor advisories and apply patches
Chain of evidence and sources
AVideo-Encoder 8.1.0 öncesi sürümlerde kimlik doğrulamasız komut çalıştırma açığı bulunmaktadır.
Saldırganlar webSiteRootURL parametresi üzerinden oturum durumunu kötüye kullanabilir.
Zaafiyet ffprobe ve ffmpeg komutlarına güvensiz girdi aktarılmasından kaynaklanır.
Bu güvenlik açığı 8.1.0 sürümünde giderilmiştir.
Show the technical text from the sources
AVideo is a video-sharing Platform. Prior to 8.1.0, the live-streaming endpoint `view/videosListToLive.php` accepts an attacker-named streamer in `webSiteRootURL`, calls `Login::run` in `objects/Login.php`, and trusts the returned JSON as session state. An unauthenticated remote attacker who can host an HTTP service reachable by the encoder can self-grant `isLogged` and `canStream` without legitimate credentials. The endpoint requires only nonempty `playlists_id` and `APISecret` values; `APISecret` is forwarded rather than checked against a stored secret. This path never calls `Streamer::isURLAllowed` and therefore works regardless of the operator's streamer allowlist. It fetches a second attacker-controlled video-list response and interpolates `videos[].path` without shell argument escaping into `ffprobe` and `ffmpeg` commands passed to `exec`; `isAudio` calls `isVideo` to reach the `ffprobe` command. Paths containing shell delimiters execute arbitrary operating-system commands as the web-server user. The request filter does not inspect the video-list JSON. This can disclose database and stored streamer credentials, compromise the upstream platform using those credentials, modify files owned by the web-server user, establish persistence, and deny encoder service. This issue is fixed in version 8.1.0.
