VAR-202503-0215

Vulnerability from variot - Updated: 2025-04-16 23:22

A vulnerability, which was classified as critical, was found in Tenda AC7 up to 15.03.06.44. This affects the function formSetFirewallCfg of the file /goform/SetFirewallCfg. The manipulation of the argument firewallEn leads to stack-based buffer overflow. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used. Shenzhen Tenda Technology Co.,Ltd. of AC7 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 Tenda AC7 15.03.06.44 and earlier versions, the formSetFirewallCfg function of the /goform/SetFirewallCfg file has a stack overflow vulnerability when processing the firewallEn parameter. The vulnerability is caused by the program's failure to check the parameter length. Attackers can use this vulnerability to launch attacks remotely and achieve code execution
