CVE-2025-34176: Netgate pfSense CE Suricata Package v7.0.8_2 Directory Traversal Information Disclosure
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.
Security readout for executives and security teams
Plain-English summary
This issue lets a logged-in pfSense CE user with Suricata package permissions confirm whether specific files exist on the firewall. The sources say file contents are not exposed. Business risk is mainly reconnaissance from an already-authorized account, not remote unauthenticated compromise.
Executive priority
Treat as a near-term hardening item, especially on shared-admin firewalls. It is not presented as an emergency remote compromise, but it can help an insider or compromised account map sensitive filesystem details.
Technical view
In pfSense CE Suricata package 7.0.8_2, /suricata/suricata_ip_reputation.php uses the iplist parameter in a file existence check without filtering directory traversal characters. An authenticated low-privilege user with WebCfg Suricata package rights can enumerate filesystem paths through existence responses.
Likely exposure
Exposure is limited to pfSense CE systems running the Suricata package version 7.0.8_2 and accounts granted WebCfg - Services: suricata package permissions. The provided data marks other versions as unaffected by default.
Exploitation context
The bundle does not report active exploitation, and the CVE is not marked KEV. Exploitation requires valid web interface authentication with Suricata package permissions. The disclosed impact is file-existence enumeration, not file read, write, or command execution.
Researcher notes
Evidence supports CWE-22 directory traversal in a file-exists decision path. The key constraint is authenticated access with Suricata package rights. The source bundle does not establish content disclosure, privilege escalation, public exploitation, or a named fixed release version.
Mitigation direction
Identify pfSense CE systems running Suricata package 7.0.8_2.
Apply Netgate or pfSense package guidance and the fixed package when available.
Restrict Suricata package permissions to trusted administrative users only.
Review firewall administrator accounts for unnecessary WebCfg Suricata access.
Monitor vendor issue and advisory pages for fixed-version confirmation.
Validation and detection
Inventory installed pfSense CE Suricata package versions.
Review users and groups with WebCfg - Services: suricata package permissions.
Confirm the referenced patch or fixed package is present before closing exposure.
Check web interface logs for unusual access to suricata_ip_reputation.php.
Document whether any exposed system was running version 7.0.8_2.

CWE-22: File access and web shell behavior lookup
File traversal and upload weaknesses can lead teams to review file, web shell, execution, and collection telemetry. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
The CVE wording references file access or upload behavior, so file telemetry and web shell review may help. This is a Glexia inferred lookup path, not an official MITRE, ATT&CK, or CVE Program mapping.
These fields come from the CVE record and ADP containers, not from Glexia's Take. They preserve time-varying source decisions such as CISA SSVC, KEV status, CVSS metrics, and provider references.
We collect every scored CVSS vector available in the official CNA and ADP containers. When more than one version is present, the table keeps the source vectors side by side instead of collapsing them into the highest score.

Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
