[R5] Tenable SecurityCenter devform.php message Parameter Reflected XSS

Related Vulnerabilities: CVE-2013-5911  

SecurityCenter contains a flaw that allows a reflected cross-site scripting (XSS) attack. This flaw exists because the application does not validate the 'message' parameter upon submission to the devform.php script. This may allow an attacker to create a specially crafted request that would execute arbitrary script code in a user's browser within the trust relationship between their browser and the server. This script was included as part of the development process, but not removed for the final release.
