What the vulnerability does

01Description

WWBN AVideo is an open source video platform. Prior to version 24.0, an authenticated Remote Code Execution (RCE) vulnerability was identified in AVideo related to the plugin upload/import functionality. The issue allowed an authenticated administrator to upload a specially crafted ZIP archive containing executable server-side files. Due to insufficient validation of extracted file contents, the archive was extracted directly into a web-accessible plugin directory, allowing arbitrary PHP code execution. This issue has been patched in version 24.0.
