VAR-202404-2904
Vulnerability from variot - Updated: 2025-08-10 23:37TOTOLINK EX200 V4.0.3c.7646_B20201211 was discovered to contain a remote code execution (RCE) vulnerability via the FileName parameter in the setUpgradeFW function. TOTOLINK of EX200 The firmware contains a special element sanitization vulnerability.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. The TOTOLINK EX200 is a wireless N range extender developed by China's TOTOLINK Electronics. It is primarily used to extend the coverage of existing Wi-Fi networks and resolve signal dead zones. An attacker could exploit this vulnerability to execute arbitrary code

VAR-202404-2861
Vulnerability from variot - Updated: 2025-08-10 23:34TOTOLINK EX200 V4.0.3c.7646_B20201211 was discovered to contain a Denial-of-Service (DoS) vulnerability in the RebootSystem function which can reboot the system without authorization. TOTOLINK of EX200 The firmware contains a special element sanitization vulnerability.Service operation interruption (DoS) It may be in a state. The TOTOLINK EX200 is a wireless N range extender released by China's Jiweng Electronics (TOTOLINK). It is primarily used to extend the coverage of existing Wi-Fi networks and resolve signal dead zones.
The TOTOLINK EX200 suffers from a denial of service vulnerability caused by a failure to properly validate user input in the RebootSystem method

Affected is the function getSaveConfig of the file /cgi-bin/cstecgi.cgi?action=save\u0026setting. The manipulation of the argument http_host leads to buffer overflow. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used. VDB-273258 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 EX200 Firmware has a classic buffer overflow vulnerability.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. \u200cTOTOLINK EX200 is a 2.4G wireless N range extender designed to expand the coverage of existing Wi-Fi networks. The vulnerability stems from the function getSaveConfig in the file /cgi-bin/cstecgi.cgi?action=save\u0026setting as parameter http_host, which causes a buffer overflow.
