CVE-2025-34176
MediumCVSS 4.3Exploitation Probability (EPSS)
Very high risk96th percentile - higher than 96% of all known CVEs
Summary
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.
Risk Assessment
An attacker with Suricata package permissions can check for the existence of arbitrary files, potentially revealing sensitive configuration or system structure information.
Recommendation
Update pfSense CE to the latest patched version and implement input validation for the iplist parameter to block directory traversal sequences.
Other vulnerabilities in pfSense CE
See all- 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-2025-34177Medium
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.
- 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.
Original NVD description (English source)
In pfSense CE /suricata/suricata_ip_reputation.php, the value of the iplist parameter is not sanitized of directory traversal-related strings/characters. This value is directly used in a file existence check operation. While the contents of the file cannot be read, the server reveals whether the file exists, which enables an attacker to enumerate files on the target. The attacker must be authenticated with at least "WebCfg - Services: suricata package" permissions.
