Vulnerability from variot - Updated: 2025-02-27 02:51

A vulnerability classified as problematic was found in TOTOLINK EX1800T 9.1.0cu.2112_B20220316. This vulnerability affects the function sub_40662C of the file /cgi-bin/cstecgi.cgi. The manipulation of the argument ssid leads to stack-based buffer overflow. The attack can be initiated remotely. The exploit has been disclosed to the public and may be used. TOTOLINK of ex1800t 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. TOTOLINK EX1800T is a Wi-Fi range extender from China's TOTOLINK Electronics.

There is a stack overflow vulnerability in the cstecgi.cgi sub_40662C of the TOTOLINK EX1800T. The vulnerability is caused by the ssid parameter of the sub_40662C function of the /cgi-bin/cstecgi.cgi 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
