"The remote host is running a version of the SiteEnable CMS package
that has several vulnerabilities :

  - SQL Injection Vulnerability
    Due to a failure to properly sanitize user input to the 'sortby' 
    parameter of the 'content.asp' script, an attacker can 
    execute SQL queries against the underlying database.

  - Multiple Cross-Site Scripting Vulnerabilities
    An attacker can pass arbitrary HTML and script code through
    the 'contenttype' parameter (and likely others) of the 
    'content.asp' script to be executed in a user's browser in
    the context of the affected website." );
