Vulnerability from variot - Updated: 2025-10-12 23:29

A vulnerability was detected in Tenda AC18 15.03.05.19. This affects an unknown function of the file /goform/WizardHandle. The manipulation of the argument WANT/mtuvalue results in stack-based buffer overflow. The attack can be launched remotely. The exploit is now public and may be used. Shenzhen Tenda Technology Co.,Ltd. of AC18 The firmware contains a buffer error vulnerability and a stack-based buffer overflow vulnerability.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. in July 2016, primarily for villas and large homes.

The Tenda AC18 suffers from a buffer overflow vulnerability caused by a failure to perform a valid bounds check on the WANT/mtuvalue parameter in the /goform/WizardHandle file. This vulnerability could allow an attacker to execute arbitrary code or cause the system to crash
