Summary
Netgate pfSense CE 2.7.0 through 2.9.0 contains an OS command injection vulnerability that allows authenticated users with QinQ edit privilege to run commands by storing an unvalidated parent interface name. Attackers can save a crafted 'if' value, then edit the QinQ entry so it is interpolated into ifconfig shell commands, executing commands as root.
