CVE-2025-34178: Netgate pfSense CE Suricata package v7.0.8_2 Stored Cross-Site Scripting
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.
Security readout for executives and security teams
Plain-English summary
This is a stored cross-site scripting issue in the pfSense CE Suricata package. An already-authenticated user with Suricata package privileges can save a crafted policy name that is later displayed without proper HTML sanitization. Business impact is mainly admin-console trust, session integrity, and configuration workflow risk, not direct firewall bypass.
Executive priority
Treat as a moderate-priority administrative interface flaw. Prioritize internet-managed or shared-admin pfSense environments, and combine patching with access review. It is less urgent than unauthenticated firewall compromise, but stored XSS inside firewall administration can still support credential or configuration abuse.
Technical view
CVE-2025-34178 affects pfSense CE Suricata package version 7.0.8_2 in /suricata/suricata_app_parsers.php. The policy_name parameter is stored and rendered without sanitizing HTML-related characters, causing CWE-79 stored XSS. CVSS v4.0 is 5.1 with network access, low complexity, low privileges, and user interaction required.
Likely exposure
Exposure appears limited to pfSense CE systems running the Suricata package version 7.0.8_2, especially where non-administrator accounts hold "WebCfg - Services: suricata package" permissions. Systems without that package or version are not identified as affected in the bundle.
Exploitation context
The source bundle does not show CISA KEV listing or active exploitation evidence. Exploitation requires authentication and relevant Suricata web configuration permissions, plus a later user viewing affected content. The issue is meaningful in shared administration environments but is not described as remotely exploitable without credentials.
Researcher notes
Key facts are source-grounded: affected product is Netgate pfSense CE Suricata package 7.0.8_2, weakness is CWE-79, CVSS v4.0 score is 5.1, and privilege requirement is Suricata WebCfg access. The bundle includes a patch commit, but does not name a fixed package version.
Mitigation direction
Update the pfSense CE Suricata package to a build containing the referenced patch.
If no fixed package is visible, follow Netgate or pfSense Redmine guidance before changing production systems.
Restrict Suricata package permissions to trusted administrators only.
Review existing Suricata policy names for unexpected or suspicious content.
Monitor pfSense package advisories for fixed-version confirmation.
Validation and detection
Inventory pfSense CE systems with the Suricata package installed.
Confirm whether installed Suricata package version is 7.0.8_2.
Check that Suricata policy names are HTML-escaped after patching.
Review pfSense user roles for Suricata package permissions.
Review administrative logs for unexpected Suricata policy changes.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
