Administrative password disclosure via unauthenticated endpoint
Published Aug 24, 2026 · Updated Aug 24, 2026
Missing authentication in KAON PG5298A before 3.0.82 and PG5298B before 4.0.82 allows remote attackers to read an administrative password. An otherwise protected device endpoint returns sensitive configuration data, including the administrative-portal password, without verifying a session or other credentials. The endpoint is reachable from an adjacent network without authentication; CERT Polska has not published its path or handler logic.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
