CyberRota Analysis
AI-GeneratedThe Kaltura HTML5 player is vulnerable to unauthenticated remote code execution due to unsafe data deserialization and improper filesystem path handling in mwEmbedLoader.php. An attacker can exploit this flaw to write arbitrary files to web-accessible locations, potentially executing code with the privileges of the web server user. Organizations using affected versions of the Kaltura HTML5 player should prioritize patching this vulnerability to mitigate the risk of exploitation.

Original NVD Description
The Kaltura HTML5 player (mwEmbed / html5lib) contains an unauthenticated remote code execution vulnerability caused by unsafe data deserialization and unsanitized filesystem path construction. mwEmbedLoader.php accepts a user‑controlled ServiceUrl, whose response is passed to unserialize(), and the resulting object’s fields are written to a cache path derived from attacker‑supplied uiconf_id without proper path validation. An attacker can write arbitrary files into web‑accessible locations and achieve code execution as the webserver user. Affected versions include html5lib v2.45, v2.103 and earlier, and other v2.x releases exposing the vulnerable endpoint.
