Name of the Vulnerable Software and Affected Versions: Sonatype Nexus Repository Manager versions prior to 3.31.0

Description: The issue allows a remote authenticated attacker to obtain a list of blob files and read the content of a blob file via a GET request without having the necessary access permissions. This is achieved by exploiting the lack of proper access control in the software.

Recommendations: For versions prior to 3.31.0, update to version 3.31.0 or later to resolve the issue. As a temporary workaround, consider restricting access to the blob files and implementing additional access controls to minimize the risk of exploitation.
