Multiple vulnerabilities have been reported in Juniper IVE OS, which can be exploited by malicious people to conduct cross-site scripting, HTTP response splitting, and redirection attacks and bypass certain security restrictions.

1) An input validation error in the homepage.cgi script can be exploited to e.g. redirect users to an (untrusted) fake site specified by an attacker.

This vulnerability is reported in version 6.5R1 (Build 14599) and version 6.5R2 (Build 14951) using Model SA-2000. Other versions prior to 6.5R3.1 (build 15255) may also be affected.

2) An authentication error when handling input passed via the "url" parameter to /dana-na/download/ script can be exploited to access otherwise restricted scripts e.g. /dana/home/launch.cgi.

3) Input passed to the "redir" parameter in /dana-na/meeting/meeting_testresult.cgi (when "java" is set to "1"), "url" parameter in /dana-na/home/launch.cgi, "si" parameter in /dana/fb/smb/rd.cgi, and "dir" parameter in /dana/fb/smb/wu.cgi is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.

4) Input passed to the "file" parameter in /dana/fb/smb/wfmd.cgi is not properly sanitised before being returned to the user. This can be exploited to insert arbitrary HTTP headers, which are included in a response sent to the user. This allows arbitrary HTML and script code to be executed in a user's browser session in context of an affected site.

Vulnerabilities #2 through #4 are reported in versions prior to 5.5R7.1, 6.0R8, 6.1R5, 6.2R3, and 6.3R1.

Solution
Update to version 5.5R7.1, 6.0R8, 6.1R7, 6.2R3, 6.3R2, and 6.5R3.1 (build 15255).
