VAR-202503-0542

Vulnerability from variot - Updated: 2025-06-12 02:27

A vulnerability was found in TOTOLINK EX1800T up to 9.1.0cu.2112_B20220316. It has been classified as critical. Affected is the function setPasswordCfg of the file /cgi-bin/cstecgi.cgi. The manipulation of the argument admpass 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. TOTOLINK of ex1800t The firmware contains a buffer error vulnerability, a stack-based buffer overflow vulnerability, and an out-of-bounds write 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. The vulnerability is caused by the setPasswordCfg function 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
