CVE-2025-34178: Netgate pfSense CE Suricata package v7.0.8_2 Stored Cross-Site Scripting

Noroxi assessment

Priority: Monitor (action score 22/100)

  • 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: 5.4% (FIRST EPSS); higher than 92.7% of all records.
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No special conditions are required; it is repeatable.
  • No fixed version is recorded, but the references include a patch (commit or PR) link.

Low priority for now. See the fix and affected versions sections below.

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

In pfSense CE /suricata/suricata_app_parsers.php, the value of the policy_name parameter is not sanitized of HTML-related strings/characters before being directly displayed. This can result in stored cross-site scripting. The attacker must be authenticated with at least "WebCfg - Services: suricata package" permissions.
