    Action Type Old Value New Value
    Added Description A cross-site scripting (XSS) vulnerability exists in the LB-Link BL-CPE300M 01.01.02P42U14_06 router’s web interface. The /goform/goform_get_cmd_process endpoint fails to sanitize user input in the cmd parameter before reflecting it into a text/html response. This allows unauthenticated attackers to inject arbitrary JavaScript, which is executed in the context of the router’s origin when the crafted URL is accessed. The issue requires user interaction to exploit.
