description

Nexus Repository 3 versions before 3.98.0 allow users with capability-creation permission to enable Rut Auth without realm-administration rights. An attacker with that permission could cause the instance to accept identity headers and impersonate an existing account, potentially including an administrator.

mitigation

Upgrade Nexus Repository 3 to version 3.98.0 or later. Until upgraded, restrict the capability-creation permission to trusted administrators and review existing Rut Auth capabilities.

fixed in 3.98.0
