Citrix NFuse 1.51 and 1.6
Citrix NFuse newer than 1.6
Cross Site Scripting
The remote host is running a Citrix NFuse Server prior 1.6. There is a bug in getLastError() which makes it vulnerable to cross site scripting attacks. An attacker may use this bug to run arbitrary web code in the context of the web site.
You should install or upgrade the software to the latest version. See http://www.citrix.com for more details. Change the default directory of the affected suite to make it harder to run pre-defined and automated attacks against the vulnerability. A solution named Appgate is able to secure Citrix NFuse and MetaFrame. See http://www.appgate.com/knowledge_center/2_White_Papers_and_Other_Documentation/Gerald_Matt_GSEC.pdf for more details. Also limit unwanted connections and communications with firewalling if possible.
