What is CVE-2019-25390?

Smoothwall Express 3.1-SP4-polar-x86_64-update9 contains multiple reflected cross-site scripting vulnerabilities in the interfaces.cgi script. Attackers can exploit these vulnerabilities by injecting malicious scripts through various parameters, including GREEN_ADDRESS, GREEN_NETMASK, RED_DHCP_HOSTNAME, RED_ADDRESS, and others. By crafting specially designed POST requests to interfaces.cgi with injected JavaScript payloads, an attacker can execute arbitrary scripts in the context of an authenticated administrator session, potentially compromising the system's integrity and confidentiality.
