The Tenda F453 router version 1.0.0.3 contains a buffer overflow vulnerability in the fromSetIpBind function of the /goform/SetIpBind endpoint. The vulnerability arises from improper validation of the 'page' argument, allowing an attacker to overflow a buffer remotely. This can lead to potential compromise of the device's confidentiality, integrity, and availability. The vulnerability has a CVSS 4.0 score of 8.7, reflecting its high severity and ease of exploitation without user interaction or elevated privileges. The vulnerability was publicly disclosed on 2026-03-01, but no official patch or vendor advisory has been provided yet.

Successful exploitation of this buffer overflow vulnerability can allow a remote attacker to execute arbitrary code or cause a denial of service on the affected Tenda F453 device. This impacts the confidentiality, integrity, and availability of the device and potentially the network it serves. The vulnerability requires only low privileges and no user interaction, increasing the risk of exploitation. However, there are currently no known exploits actively used in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
