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.
AnalysisAI
Unauthenticated administrators in WWBN AVideo versions before 24.0 can achieve remote code execution by uploading malicious ZIP files through the plugin upload functionality, which extracts files without proper validation into web-accessible directories. This allows attackers to execute arbitrary PHP code on the server with high impact to confidentiality, integrity, and availability. No patch is currently available for affected PHP installations using vulnerable AVideo versions.
