Vulnerability from variot

A vulnerability, which was classified as critical, has been found in Totolink A7100RU 7.4cu.2313_B20191024. Affected by this issue is the function main of the file /cgi-bin/cstecgi.cgi?action=login of the component HTTP POST Request Handler. The manipulation of the argument flag leads to buffer overflow. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. VDB-248942 is the identifier assigned to this vulnerability. TOTOLINK of A7100RU 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 A7100RU is a wireless router made by China Zeon Electronics (TOTOLINK) Company. The vulnerability is caused by the failure of the parameter flag in the file /cgi-bin/cstecgi.cgi?action=login to correctly verify the length of the input data. A remote attacker can exploit this vulnerability. The vulnerability could execute arbitrary code on the system or lead to a denial of service attack
