VAR-202510-0241

Vulnerability from variot - Updated: 2025-11-22 23:21

A security vulnerability has been detected in TOTOLINK N600R up to 4.3.0cu.7866_B20220506. This impacts the function setWiFiBasicConfig of the file /cgi-bin/cstecgi.cgi of the component HTTP Request Handler. Such manipulation of the argument wepkey leads to buffer overflow. It is possible to launch the attack remotely. The exploit has been disclosed publicly and may be used. TOTOLINK of n600r 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 N600R is a dual-band wireless router released by the Korean brand TOTOLINK in 2013. It supports concurrent operation in the 2.4GHz and 5GHz bands and offers a maximum wireless transmission rate of 300Mbps.

The TOTOLINK N600R suffers from a buffer overflow vulnerability caused by the wepkey parameter in the /cgi-bin/cstecgi.cgi file failing to properly validate the length of input data. An attacker could exploit this vulnerability to execute arbitrary code on the system or cause a denial of service
