Summary
Shenzhen Tenda AC7 firmware version V03.03.03.01_cn and prior does not implement CSRF protections for administrative functions in the web management interface. The interface does not enforce anti-CSRF tokens or robust origin validation, which can allow an attacker to induce a logged-in administrator to perform unintended state-changing requests and modify router settings.
