| pfsense | ≥ 2.7.1, ≤ 2.9.0 |
Netgate pfSense CE from 2.7.1 through 2.9.0 contains a CRLF injection vulnerability in services_unbound_advanced.php that allows authenticated users with DNS Resolver: Advanced privilege to inject Unbound directives. Attackers can embed CR/LF characters in the unvalidated sock_queue_timeout parameter, which is written raw into unbound.conf, to override local records and forwarding for all clients.
