-- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of Juniper SA Series devices. Authentication is
not required to exploit this vulnerability.

The specific flaw exists within the meeting_testjava.cgi page which is
used to test JVM compatibility. When handling the DSID HTTP header the
code allows an attacker to inject arbitrary javascript into the page.
This can be abused by an attacker to perform a cross-site scripting
attack on the device.

-- Vendor Response:
Juniper states:
Development has confirmed that the fix to this issue will be available
in IVE OS versions 6.5r7 and 7.0r3.  Both IVE OS 6.5r7 and 7.0r3 are
planned to be available to customers in early November 2010.

Customers can sign up for proactive alerts of IVE OS software releases
by visiting the Juniper Networks Support Center and selecting "Subscribe
