Technical Description
An XSS vulnerability in pxc_Dot1xCfg.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.
Remediation
Check the references section for vendor advisories and patches from phoenixcontact. Update fl_nat_2008_firmware to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
