Exploit Included: Yes |
Version(s): Model SA-2000, 6.5R1 (Build 14599)|
A vulnerability was reported in Juniper Secure Access (IVE). A remote user can conduct cross-site scripting attacks.|
The IVE web interface does not properly filter HTML code from user-supplied input before displaying the input. A remote user can create a specially crafted URL that, when loaded by a target user, will cause arbitrary scripting code to be executed by the target user's browser. The code will originate from the IVE device and will run in the security context of that site. As a result, the code will be able to access the target user's cookies (including authentication cookies), if any, associated with the site, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.

PR09-16: Juniper Secure Access series (Juniper IVE) XSS
Vulnerability found: 12th October 2009
Severity: Medium (Script injection)
There is a Cross-site Scripting vulnerability on Juniper, IVE web interface.
Procheckup has found by making a malformed request to the IVE Web
interface without authentication, that a vanilla cross site scripting
(XSS) attack is possible.
Successfully tested on:
Juniper Networks IVE version 6.5R1 (Build 14599)
Proof of concept:
An attacker may be able to cause execution of malicious scripting code
in the browser of a user who clicks on a link or visits a malicious
webpage. The malicious code would run in the security context of the
This type of attack can result in non-persistent defacement of the
target site, or the redirection of confidential information (i.e.:
passwords or session IDs) to unauthorised third parties.
Ensure that the firewall's management interface is disabled on the
Internet connected interface, by disabling WeBUI within service
options on the Internet connected interface.
