VAR-202504-3472
Vulnerability from variot - Updated: 2025-05-17 03:44TOTOLINK A800R V4.1.2cu.5137_B20200730 was found to contain a buffer overflow vulnerability in downloadFile.cgi through the v14 parameter. TOTOLINK of a800r 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. TOTOLINK A800R is a wireless router from China's TOTOLINK Electronics. The vulnerability is caused by the failure of the v14 parameter in downloadFile.cgi to correctly verify the length of the input data. Remote attackers can exploit this vulnerability to execute arbitrary code on the system or cause a denial of service

VAR-202504-3463
Vulnerability from variot - Updated: 2025-05-10 23:09TOTOLINK A800R V4.1.2cu.5137_B20200730 was found to contain a buffer overflow vulnerability in downloadFile.cgi through the v25 parameter. TOTOLINK of a800r 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. TOTOLINK A800R is a wireless router from China's TOTOLINK Electronics. The vulnerability is caused by the failure of the v25 parameter in downloadFile.cgi to correctly verify the length of the input data. Remote attackers can exploit this vulnerability to execute arbitrary code on the system or cause a denial of service attack
