Summary
Nexus Repository 3 had an endpoint for changing the administrator password during initial onboarding. It did not verify that onboarding was still in progress, relying on a local artifact. An account with nexus:* permission could invoke the endpoint outside the intended flow to replace the admin password, and existing sessions were not invalidated.
Risk Assessment
The risk includes unauthorized admin password changes by an account with nexus:* permission, potentially leading to repository takeover. Lack of session invalidation increases the risk of persistent unauthorized access.
Recommendation
It is recommended to update Nexus Repository 3 to a patched version and to check for any unauthorized password changes. Also, invalidate all sessions after the update.
Original NVD description (English source)
Nexus Repository 3 contained an endpoint used to change the administrator account password during initial onboarding. This endpoint did not verify that onboarding was still in progress before allowing the password change, relying instead on the presence of a local onboarding artifact. As a result, an account holding the nexus:* permission could invoke the endpoint outside the intended onboarding flow to replace the administrator password, and existing sessions were not invalidated after the change.
