CVE-2025-28059Network attack vector

Unauthorized access via unrevoked sessions and API tokens

Published Apr 18, 2025 · Updated Apr 22, 2025

Broken access control in Nagios Network Analyzer 2024R1.0.3 allows remote attackers to retain access via stale sessions and API tokens. The backend neither checks whether the account still exists during API requests nor invalidates its active session metadata and API tokens when an administrator deletes it. Possession of a session or token established before deletion is required; it remains usable to read system data, alter profile details, and create queries.
