CVE-2025-34175Network attack vector

Reflected XSS via unencoded filehash parameter

Published Sep 9, 2025 · Updated Sep 9, 2025

Reflected XSS in the Suricata package for Netgate pfSense CE 7.0.8_2 allows remote attackers to run script via a crafted filehash. suricata_filecheck.php inserts filehash into several outbound-link URLs without URL encoding, allowing markup to escape the attribute context. Exploitation requires an authenticated pfSense user to open the crafted request; injected script can read data available to that web session.
