Router takeover via missing CSRF tokens
Published Jun 17, 2021 · Updated Aug 3, 2024
Cross-site request forgery in TrendNet TW100-S4W1CA 2.3.32 allows remote attackers to take over the router via a malicious web page. The router management interface accepts state-changing GET requests without anti-CSRF tokens, so requests embedded in attacker-controlled HTML execute with a logged-in administrator's session. Exploitation requires an authenticated administrator to load the page; demonstrated changes include enabling remote management, altering access controls, and resetting the administrator password.
