CVE-2025-2991Public exploitNetwork attack vector

Unauthenticated configuration changes via AdvSetWrlmacfilter

Published Mar 31, 2025 · Updated Mar 31, 2025

Improper access control in the Tenda FH1202 1.2.0.14(408) web interface allows remote attackers to alter wireless MAC-filter settings. The AdvSetWrlmacfilter handler processes unauthenticated requests without enforcing the privileges required to change that configuration. Network access to the management interface is the only reported gate, and exploitation changes router configuration without reading data or interrupting service.
