CVE-2025-41752: Reflected XSS vulnerability in pxc_portSfp.php

Noroxi assessment

Priority: Monitor (action score 31/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 9.7% (FIRST EPSS); higher than 95.5% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: Phoenix Contact FL NAT 2008 3.50; Phoenix Contact FL NAT 2208 3.50; Phoenix Contact FL NAT 2304-2GC-2SFP 3.50.

Low priority for now. Upgrade to Phoenix Contact FL NAT 2008 3.50; Phoenix Contact FL NAT 2208 3.50; Phoenix Contact FL NAT 2304-2GC-2SFP 3.50 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

An XSS vulnerability in pxc_portSfp.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.
