CVE-2022-30105

Estado: ModificadaCrítica (9.8)—

In Belkin N300 Firmware 1.00.08, the script located at /setting_hidden.asp, which is accessible before and after configuring the device, exhibits multiple remote command injection vulnerabilities. The following parameters in the [form name] form; [list vulnerable parameters], are not properly sanitized after being submitted to the web interface in a POST request. With specially crafted parameters, it is possible to inject a an OS command which will be executed with root privileges, as the web interface, and all processes on the device, run as root.
