Technical details

A stack-based buffer overflow vulnerability exists in the Tenda F451 router (firmware version 1.0.0.7) within the 'httpd' component. The flaw is located in the 'fromSafeMacFilter' function in the '/goform/SafeMacFilter' file. An attacker can trigger the overflow by manipulating the 'page/menufacturer' argument in a network request. While the attack can be executed remotely, CVSS metrics suggest low privileges (PR:L) are required. Successful exploitation can lead to complete compromise of the device's confidentiality, integrity, and availability. A public exploit has been disclosed.
