VAR-202510-2241

Vulnerability from variot - Updated: 2025-11-19 19:40

A security vulnerability has been detected in TOTOLINK A3300R 17.0.0cu.557_B20221024. This affects the function setDmzCfg of the file /cgi-bin/cstecgi.cgi. The manipulation of the argument ip leads to buffer overflow. It is possible to initiate the attack remotely. The exploit has been disclosed publicly and may be used. The TOTOLINK A3300R is a dual-band wireless router manufactured by TOTOLINK Electronics Co., Ltd. in China, primarily used in home and small network environments. This vulnerability stems from the fact that the parameter ip in the function setDmzCfg in the file /cgi-bin/cstecgi.cgi fails to properly validate the length of the input data. Attackers could exploit this vulnerability to execute arbitrary code on the system or cause a denial-of-service attack
