Limited Authentication Bypass for Media Files

Moderate severity GitHub Reviewed Published May 19, 2022 in opencast/opencast • Updated Jan 27, 2023

Package

maven org.opencastproject:opencast-ingest-service-impl (Maven)

Affected versions

< 10.14
>= 11.0, < 11.7

Patched versions

10.14
11.7

Description

Prior to Opencast 10.14 and 11.7, users could pass along URLs for files belonging to organizations other than the user's own, which Opencast would then import into the current organization, bypassing organizational barriers.

Impact

The vulnerability allows attackers to bypass organizational barriers. Attackers must have full access to Opencast's ingest REST interface, and also know internal links to resources in another organization of the same Opencast cluster.

If you do not run a multi-tenant cluster, you are not affected by this issue.

Patches

This issue is fixed in Opencast 10.14 and 11.7.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
