Description
The issue is due to improper validation of user-supplied input in the web-based management interface of the affected routers. An attacker could exploit this by sending crafted HTTP requests to an affected device, potentially allowing them to execute arbitrary code as the root user on the underlying operating system or cause the device to reload, resulting in a denial of service (DoS) condition. To exploit this, an attacker would need to have valid administrator credentials on the affected device.
