Product Affected:
This issue can affect any product or platform running Junos OS with J-Web enabled.
Junos J-Web was missing 'X-Frame-Options' HTTP header that may facilitate Clickjacking type of attacks against authenticated or unauthenticated pages on J-Web. An attacker can potentially trick Junos J-Web users into performing certain administrative tasks.

Juniper SIRT is not aware of any malicious exploitation of this vulnerability.

This issue has been assigned CVE-2015-3004.
J-Web now includes the appropriate 'X-Frame-Options' header in HTTP responses. J-Web also includes defensive code in the UI for old browsers that may not support 'X-Frame-Options' header.
