Background
Opencast is an open-source system for managing and publishing audiovisual content. It provides a platform for recording, processing, and distributing multimedia content. The Opencast kernel is a core component of the Opencast system, responsible for managing user access and permissions. This vulnerability affects Opencast versions 2.2.3 and older.
Vulnerability Detail
The vulnerability in Opencast allows users to bypass access restrictions by exploiting an incorrect permission assignment. When user names overlap, the Opencast search service used for publication to the media modules and players mishandles access control. This means that users only need to match part of the user name used for the access restriction. For example, a user with the role ROLE_USER will have access to recordings published only for ROLE_USER_X. This vulnerability can lead to unauthorized access to sensitive content and compromise the security of the Opencast system.
