Upstream source description

Netgate pfSense CE through 2.9.0 contains an OS command injection vulnerability that allows authenticated users with gateway edit privileges to execute commands as root by injecting shell metacharacters into an IPv6 link-local zone index. Attackers can set a gateway Monitor IP whose unvalidated zone carries a payload, which start_dpinger() passes unescaped to the dpinger shell command when monitoring is applied.
