Vulnerability from variot

A vulnerability, which was classified as critical, has been found in Tenda G3 15.11.0.20. This issue affects the function formSetDebugCfg of the file /goform/setDebugCfg. The manipulation of the argument enable/level/module leads to stack-based buffer overflow. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used. NOTE: The vendor was contacted early about this disclosure but did not respond in any way. Shenzhen Tenda Technology Co.,Ltd. of G3 An out-of-bounds write vulnerability exists in firmware.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. Tenda G3 is a Qos VPN router from China's Tenda company. The vulnerability is caused by the enable/level/module parameter of the formSetDebugCfg function in the /goform/setDebugCfg file failing to properly verify the length of the input data. Attackers can exploit this vulnerability to execute arbitrary code on the system or cause the application to crash
