Short explanation
Netgate pfSense CE through version 2.9.0 contains a local file read vulnerability allowing users with Dynamic DNS client privileges to read files as root.
It matters because it allows authorized attackers to extract sensitive system files by logging them into the system log. The patch status could not be verified from the reviewed official sources.
What should be done?
- Follow vendor advisories to apply available updates
- Audit and restrict Dynamic DNS client privileges tightly
- Monitor system logs for unauthorized file read attempts
