## Overview

Netgate pfSense CE 2.7.0 through 2.9.0 contains a configuration injection vulnerability that allows authenticated users with IPsec Mobile privileges to execute commands as root via the login_banner field. Attackers can submit a single-line banner containing '}' to escape the unquoted strongswan.conf attr value and define charon.start-scripts entries that charon executes as root on restart.
