Does this matter?
EPSS puts the probability of exploitation in the next 30 days at 17.3%, higher than 97% of all known CVEs. Patch or mitigate before the next change window.
Description
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.
