Technical details
A CRLF injection vulnerability exists in services_unbound_advanced.php where the sock_queue_timeout parameter is written without sanitization into unbound.conf. Authenticated users holding the "DNS Resolver: Advanced" privilege can embed CR/LF characters to break out of the parameter line and inject arbitrary Unbound directives. The attacker gains the ability to override local DNS records and forwarding rules for all network clients connected to the firewall.
