CVE-2025-41749: Phoenixcontact fl switch 2008f firmware cross-site scripting vulnerability

Phoenixcontact · Fl Switch 2008f Firmware

An XSS vulnerability in port_util.php can be used by an unauthenticated remote attacker to trick an authenticated user to click on the link provided by the attacker in order to change parameters available via web based management (WBM). The vulnerability does not provide access to system-level resources such as operating system internals or privileged functions. Access is limited to device configuration parameters that are available in the context of the web application. The session cookie is secured by the httpOnly Flag. Therefore an attacker is not able to take over the session of an authenticated user.
