VAR-202407-2456
Vulnerability from variot - Updated: 2025-08-21 23:41A vulnerability classified as critical has been found in TOTOLINK A3700R 9.1.2u.5822_B20200513. Affected is the function setWanCfg of the file /cgi-bin/cstecgi.cgi. The manipulation of the argument hostName leads to command injection. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used. VDB-272574 is the identifier assigned to this vulnerability. NOTE: The vendor was contacted early about this disclosure but did not respond in any way. TOTOLINK of a3700r Firmware contains a command injection vulnerability.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. The TOTOLINK A3700R is a wireless router produced by TOTOLINK (China Jiong Electronics), a Taiwanese network equipment manufacturer. This vulnerability could lead to serious consequences, such as gaining control of the device, causing device failure, or causing it to be used for other malicious activities

(DoS) It may be in a state. TOTOLINK A3700R is a wireless router produced by China's TOTOLINK Electronics.
TOTOLINK A3700R has a stack buffer overflow vulnerability. The vulnerability is caused by the ssid in the setWiFiGuestCfg 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

VAR-202504-1154
Vulnerability from variot - Updated: 2025-07-04 23:41A vulnerability, which was classified as critical, has been found in TOTOLINK A3700R 9.1.2u.5822_B20200513. This issue affects the function setWiFiEasyCfg/setWiFiEasyGuestCfg of the file /cgi-bin/cstecgi.cgi of the component Password Handler. The manipulation leads to improper access controls. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way. TOTOLINK of a3700r There are unspecified vulnerabilities in the firmware.Information is tampered with and service operation is interrupted (DoS) It may be in a state. TOTOLINK A3700R is a wireless router that provides wireless network connection function.
TOTOLINK A3700R has an improper access control vulnerability, which is caused by the setWiFiEasyCfg/setWiFiEasyGuestCfg function in the /cgi-bin/cstecgi.cgi file failing to properly handle specific requests. No detailed vulnerability details are currently provided
