Summary

Netgate pfSense CE through 2.9.0 contains a local file read vulnerability that allows users with the Dynamic DNS client privilege to read files as root by setting a file:// custom Update URL in services_dyndns_edit.php. Attackers can set a non-matching Result Match string so _checkStatus() logs file contents such as /conf/config.xml or /etc/master.passwd to the system log.

Risk Assessment

An attacker can read sensitive system files, including passwords and configurations, potentially leading to full system compromise. The risk affects users with Dynamic DNS privileges.

Recommendation

Upgrade pfSense CE to a version newer than 2.9.0 if available, or restrict Dynamic DNS privileges to trusted users only. Monitor system logs for unauthorized file access.
