Vulnerability from variot

A vulnerability, which was classified as critical, was found in TOTOLINK A7000R 9.1.0u.6268_B20220504. Affected is the function setWizardCfg of the file /cgi-bin/cstecgi.cgi. The manipulation of the argument ssid leads to buffer overflow. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used. The identifier of this vulnerability is VDB-272784. NOTE: The vendor was contacted early about this disclosure but did not respond in any way. TOTOLINK of a7000r 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 A7000R is a wireless router produced by China's TOTOLINK Electronics.

There is a buffer overflow vulnerability in the TOTOLINK A7000R 9.1.0u.6268_B20220504 version. The vulnerability is caused by the ssid parameter in the setWizardCfg function of the /cgi-bin/cstecgi.cgi page failing 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
