"The Ivanti Connect Secure installed on the remote host is 9.x or 22.x. It is, therefore, affected by 
a CRLF vulnerability.  This vulnerability allows an authenticated high-privileged user to inject 
malicious code on a victim’s browser, thereby leading to cross-site scripting attack.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
