Settings modification via missing CSRF request validation
Published Feb 3, 2026 · Updated Feb 3, 2026
Cross-site request forgery in Tenda AC7 03.03.03.01_cn and earlier allows remote attackers to modify router settings. The administrative web interface accepts state-changing requests without anti-CSRF tokens or robust origin validation. Exploitation requires an administrator with an active authenticated session to be induced to submit an attacker-controlled request, and the resulting action runs with that administrator's privileges.
