A vulnerability classified as critical has been found in Opencast up to 7.5/8.0. Affected is an unknown code of the file Id.compact() of the component Media Handler. The manipulation as part of a String leads to a resource injection vulnerability. CWE is classifying the issue as CWE-99. The product receives input from an upstream component, but it does not restrict or incorrectly restricts the input before it is used as an identifier for a resource that may be outside the intended sphere of control. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

Opencast before 8.1 and 7.6 allows almost arbitrary identifiers for media packages and elements to be used. This can be problematic for operation and security since such identifiers are sometimes used for file system operations which may lead to an attacker being able to escape working directories and write files to other locations. In addition, Opencast's Id.toString(?) vs Id.compact(?) behavior, the latter trying to mitigate some of the file system problems, can cause errors due to identifier mismatch since an identifier may unintentionally change. This issue is fixed in Opencast 7.6 and 8.1.

The weakness was published 01/30/2020 (GitHub Repository). The advisory is shared for download at github.com. This vulnerability is traded as CVE-2020-5230 since 01/02/2020. The exploitability is told to be difficult. It is possible to launch the attack remotely. A authentication is needed for exploitation. Successful exploitation requires user interaction by the victim. There are known technical details, but no exploit is available.

Upgrading to version 7.6 or 8.0 eliminates this vulnerability.
