Short explanation
An unauthenticated installer endpoint in Avideo-Encoder interpolates request parameters into single-quoted PHP string literals without escaping, allowing PHP code injection and remote command execution.
This critical vulnerability directly threatens system security by enabling unauthenticated arbitrary command execution and persistent PHP code creation under the web-server user privileges.
What should be done?
- Update to version 8.1.0 or later
- Follow vendor security advisories
Chain of evidence and sources
AVideo-Encoder sürümlerinde kimlik doğrulamasız yükleyici uç noktası PHP kod enjeksiyonuna izin vermektedir.
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 unauthenticated installer endpoint `install/checkConfiguration.php` assembles `videos/configuration.php` by interpolating request parameters, including `webSiteRootURL`, into single-quoted PHP string literals without escaping. An attacker can terminate a literal and inject PHP that executes as the web-server user when the generated, directly requestable file is loaded. Exploitation requires `videos/configuration.php` to be absent, as on every fresh deployment or after the file is removed or moved; an existing file blocks this endpoint. The supplied `systemRootPath` must contain index.php and a connection using `databaseHost`, `databaseUser`, and `databasePass` must succeed, but the attacker can point those parameters to their own database server and needs no target credentials. The write location is also derived from `systemRootPath` without a base-directory constraint. This permits arbitrary command execution, reading and overwriting files owned by the web-server user, persistent PHP code, and control over stored database connection settings. The endpoint additionally interpolates request values into streamer and configuration INSERT statements, creating a secondary SQL-injection sink. This issue is fixed in version 8.1.0.
