Summary
In pfSense CE, in the file suricata_flow_stream.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 (XSS). The attacker must be authenticated with at least 'WebCfg - Services: suricata package' permissions.
Risk Assessment
The risk involves an authenticated user injecting a malicious script, potentially hijacking other administrators' sessions, stealing data, or performing unauthorized actions in the pfSense management interface.
Recommendation
Immediately update the Suricata package in pfSense CE to the latest version containing the security fix. Until the update, restrict access to the management interface to trusted users only.
Other vulnerabilities in pfSense CE
See all- CVE-2025-34176Medium
In pfSense CE, the suricata/suricata_ip_reputation.php file does not sanitize the iplist parameter against directory traversal sequences. This value is directly used in a file existence check, allowing an authenticated attacker to enumerate files on the server.
- CVE-2025-34175Medium
In pfSense CE, the file /usr/local/www/suricata/suricata_filecheck.php directly displays the value of the filehash parameter without sanitizing HTML-related characters/strings. This can result in reflected cross-site scripting (XSS) if the victim is authenticated.
- CVE-2025-34178Medium
In pfSense CE, in the file 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 (XSS). The attacker must be authenticated with at least 'WebCfg - Services: suricata package' permissions.
- CVE-2025-34173Medium
In pfSense CE, the file /usr/local/www/snort/snort_ip_reputation.php does not sanitize the iplist parameter for directory traversal characters before checking file existence. Although file contents are not disclosed, the server reveals whether a file exists, enabling an attacker to enumerate files on the target. The attacker must be authenticated with at least 'WebCfg - Services: Snort package' permissions.
- CVE-2025-34172Medium
In pfSense CE, the value of the showsticktablecontent parameter in /usr/local/www/haproxy/haproxy_stats.php is displayed after being read from HTTP GET requests. This enables reflected cross-site scripting when the victim is authenticated.
