What is CVE-2025-51569?
CVE-2025-51569 is a medium-severity cross-site scripting vulnerability in n/a, published on 31 Jul 2025. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Official 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.
Weakness: CWE-79
