VAR-202408-2413

Vulnerability from variot - Updated: 2025-05-23 23:24

A vulnerability, which was classified as critical, was found in Tenda G3 15.11.0.20. Affected is the function formSetSysTime of the file /goform/SetSysTimeCfg. The manipulation of the argument sysTimePolicy leads to stack-based buffer overflow. It is possible to launch the attack 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 sysTimePolicy parameter of the formSetSysTime function in the /goform/SetSysTimeCfg 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 a denial of service
