Cross-site scripting vulnerability in Citrix NFuse 1.6 and earlier does not quote results from the getLastError method, which allows remote attackers to execute script in other clients via the NFuse_Application parameter to (1) launch.jsp or (2) launch.asp.
Citrix NFuse 1.6 allows remote attackers to bypass authentication and obtain sensitive information by directly calling launch.asp with invalid NFUSE_USER and NFUSE_PASSWORD parameters.
