CyberRota Analysis
AI-GeneratedThe Kaltura HTML5 player is vulnerable to local file disclosure due to inadequate validation of the ServiceUrl parameter in mwEmbedLoader.php, allowing attackers to exploit error messages to access arbitrary internal files on the server. This vulnerability poses a significant risk as it can be exploited by unauthenticated, remote attackers. Organizations using affected versions of the Kaltura HTML5 player should prioritize remediation to prevent potential data exposure.
Original NVD Description
The Kaltura HTML5 player (mwEmbed / html5lib) contains a local file disclosure vulnerability due to improper validation of the ServiceUrl parameter in mwEmbedLoader.php. This parameter is used as the base URL for a backend request and accepts non‑HTTP schemes such as file://. When an exception or error occurs, the response is subsequently deserialized and its raw contents are reflected to the client in an error message; this enables an unauthenticated, remote attacker to read any arbitrary internal file reachable by the server. Affected versions include html5lib v2.45, v2.103 and earlier, and other v2.x releases exposing the vulnerable endpoint.
