VAR-202404-2860
Vulnerability from variot - Updated: 2025-08-10 23:38TOTOLINK EX200 V4.0.3c.7646_B20201211 was discovered to contain a remote code execution (RCE) vulnerability via the hostTime parameter in the NTPSyncWithHost function. TOTOLINK of EX200 A code injection vulnerability exists in the firmware.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

VAR-202404-3218
Vulnerability from variot - Updated: 2025-08-10 23:29TOTOLINK EX200 V4.0.3c.7646_B20201211 was discovered to contain a remote code execution (RCE) vulnerability via the langType parameter in the setLanguageCfg function. TOTOLINK of EX200 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 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-202404-2850
Vulnerability from variot - Updated: 2025-08-10 23:24TOTOLINK EX200 V4.0.3c.7646_B20201211 was discovered to contain a remote code execution (RCE) vulnerability via the webWlanIdx parameter in the setWebWlanIdx function. TOTOLINK of EX200 The firmware contains a vulnerability related to improper parameter handling.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-202404-1754
Vulnerability from variot - Updated: 2025-08-06 23:20TOTOLINK EX200 V4.0.3c.7646_B20201211 contains a Cross-site scripting (XSS) vulnerability through the ssid parameter in the setWiFiExtenderConfig function. TOTOLINK of EX200 Firmware has a cross-site scripting vulnerability.Information may be obtained. The TOTOLINK EX200 is a 2.4GHz wireless N range extender released by China-based Jiong Electronics. It is primarily used to extend the coverage of existing Wi-Fi networks and resolve signal dead zones. This vulnerability stems from the lack of effective filtering and escaping of user-supplied data in the ssid parameter of the setWiFiExtenderConfig method. Detailed vulnerability details are currently unavailable
