VAR-202503-0080

Vulnerability from variot - Updated: 2025-06-15 23:29

A vulnerability has been found in Totolink EX1800T 9.1.0cu.2112_B20220316 and classified as critical. This vulnerability affects the function loginAuth of the file /cgi-bin/cstecgi.cgi. The manipulation of the argument password leads to buffer overflow. The attack can be initiated remotely. The exploit has been disclosed to the public and may be used. TOTOLINK of ex1800t Firmware has a classic buffer overflow vulnerability.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.

Totolink EX1800T has a buffer overflow vulnerability, which is caused by the loginAuth function failing to properly verify the length of the input data. Attackers can exploit this vulnerability to execute arbitrary code or cause a denial of service
