VAR-202507-2367

Vulnerability from variot - Updated: 2025-08-09 23:03

A vulnerability, which was classified as critical, has been found in TOTOLINK T6 up to 4.1.5cu.748_B20211015. Affected by this issue is the function setDiagnosisCfg of the file /cgi-bin/cstecgi.cgi of the component HTTP POST Request Handler. The manipulation of the argument ip leads to buffer overflow. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. TOTOLINK of t6 The firmware contains a buffer error vulnerability and a classic buffer overflow vulnerability.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. The TOTOLINK T6 is a wireless dual-band router released by China's Jiweng Electronics (TOTOLINK). It supports the MQTT protocol and Telnet service.

The TOTOLINK T6 suffers from a buffer overflow vulnerability caused by a failure to properly validate the length of input data in the parameter "ip" in the file "/cgi-bin/cstecgi.cgi". An attacker could exploit this vulnerability to execute arbitrary code on the system or cause a denial of service
