VAR-202510-0241
Vulnerability from variot - Updated: 2025-11-22 23:21A 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

VAR-202510-2083
Vulnerability from variot - Updated: 2025-11-19 23:20TOTOLINK N600R v4.3.0cu.7866_B20220506 was discovered to contain a stack overflow in the ssid parameter in the setWiFiBasicConfig function. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted input. The TOTOLINK N600R is a dual-band wireless router launched by the South Korean brand TOTOLINK in 2013. It supports concurrent operation on both 2.4GHz and 5GHz bands, with a maximum wireless transmission rate of 300Mbps.
The TOTOLINK N600R contains a stack buffer overflow vulnerability. This vulnerability stems from the fact that the SSID parameter in the setWiFiBasicConfig function fails to properly validate the length of the input data

VAR-202510-2188
Vulnerability from variot - Updated: 2025-11-19 23:10TOTOLINK N600R v4.3.0cu.7866_B20220506 was discovered to contain a stack overflow in the wepkey2 parameter in the setWiFiMultipleConfig function. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted input. The TOTOLINK N600R is a dual-band wireless router launched by the South Korean brand TOTOLINK in 2013. It supports concurrent operation on both 2.4GHz and 5GHz bands, with a maximum wireless transmission rate of 300Mbps. This vulnerability stems from the fact that the wepkey2 parameter in the setWiFiMultipleConfig function fails to properly validate the length of the input data
