Smoothwall Express 3.1 'preferences.cgi' Cross-Site Scripting

Smoothwall Express 3.1-SP4-polar-x86_64-update9 contains multiple stored cross-site scripting vulnerabilities in the preferences.cgi script that allow attackers to inject malicious scripts through the HOSTNAME, KEYMAP, and OPENNESS parameters. Attackers can submit POST requests with script payloads to preferences.cgi to store malicious code that executes in the browsers of users accessing the preferences page.
