What it is

Smoothwall Express 3.1-SP4-polar-x86_64-update9 contains multiple reflected cross-site scripting vulnerabilities in the interfaces.cgi script that allow attackers to inject malicious scripts through multiple parameters including GREEN_ADDRESS, GREEN_NETMASK, RED_DHCP_HOSTNAME, RED_ADDRESS, DNS1_OVERRIDE, DNS2_OVERRIDE, RED_MAC, RED_NETMASK, DEFAULT_GATEWAY, DNS1, and DNS2. Attackers can craft POST requests to interfaces.cgi with script payloads in these parameters to execute arbitrary JavaScript in the context of authenticated administrator sessions.
