Compliance Impact

The vulnerability in the Tenda AC7 router firmware allows unauthorized modification of router settings through CSRF attacks, which could potentially lead to unauthorized access or changes in network configurations.

Such unauthorized changes may impact the security and integrity of systems that handle sensitive data, thereby potentially affecting compliance with standards and regulations like GDPR and HIPAA that require protection of data and secure administrative controls.

However, the provided information does not explicitly detail the direct impact on compliance with these regulations.

Executive Summary

The Tenda AC7 router firmware version V03.03.03.01_cn and earlier lacks Cross-Site Request Forgery (CSRF) protections in its web management interface for administrative actions.

Specifically, the interface does not implement anti-CSRF tokens or enforce robust origin validation mechanisms.

This vulnerability allows an attacker to trick a logged-in administrator into executing unintended state-changing requests, potentially modifying router settings without authorization.
