Technical details

A configuration injection vulnerability exists in the IPsec Mobile login banner field in pfSense CE 2.7.0–2.9.0. The login_banner parameter is inserted into strongswan.conf without proper quoting; attackers can close the attribute value with '}' and define charon.start-scripts entries that execute as root during daemon restart. The attack requires prior authentication with IPsec Mobile configuration privileges and triggers on firewall restart or daemon reload.
