DescriptionCVE.org

A vulnerability, which was classified as problematic, was found in Tenda AC9 15.03.02.13. This affects an unknown part. The manipulation leads to cross-site request forgery. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used.

AnalysisAI

Cross-site request forgery in Tenda AC9 router firmware 15.03.02.13 allows an attacker to trigger unintended actions like reboot or factory reset by tricking an authenticated admin into visiting a malicious page. Public exploit code exists, but no active exploitation has been confirmed.

Technical ContextAI

The vulnerability is a Cross-Site Request Forgery (CSRF) in the Tenda AC9 router's web management interface, specifically in the fromSysToolReboot and fromSysToolRestoreSet functions. CSRF exploits the trust a site has in a user's browser, allowing an attacker to forge requests that execute privileged actions if the victim is authenticated. The affected product is Tenda AC9 firmware version 15.03.2.13, a consumer-grade router.

RemediationAI

No vendor-released patch identified at time of analysis. As a workaround, disable remote management access to the router's web interface, restrict access to trusted IPs, and ensure the admin user logs out after each session. Users should monitor Tenda's support page for future firmware updates.
