A lower-privileged Admin user can escalate privileges to SuperAdmin through an unauthenticated or insufficiently authorized API or management operation. The vulnerability is network-reachable and requires an existing Admin account; no additional user interaction is needed. A successful exploitation grants an attacker full administrative control over the NSM platform and all connected security infrastructure.
