CVE-2025-20257Network attack vector

Fraudulent alerts via underauthorized API calls

Published May 21, 2025 · Updated May 21, 2025

Improper authorization in Cisco Secure Network Analytics 7.5.2 allows remote authenticated users to falsify analytics findings via API calls. A specific Manager API accepts crafted finding data from low-privileged accounts without enforcing the authorization required to create those records. Successful exploitation can hide legitimate findings or generate false alarms and alerts, affecting analytics integrity without reported disclosure or service interruption.
