Technical details

A remote command execution vulnerability exists in Sonatype Nexus Repository 3 due to the insecure deserialization of untrusted data (CWE-502) during the license upload process. An attacker must be authenticated and possess the 'nx-licensing-create' privilege to exploit this flaw. By uploading a specially crafted license file, the attacker can trigger the execution of arbitrary OS commands with the privileges of the Nexus process user. This vulnerability is addressed in version 3.92.0 and later.
