Juniper Instant Virtual Extranet (IVE) Input Validation Hole in 'editbk.cgi' Permits Cross-Site Scripting Attacks
SecurityTracker Alert ID:  1023689
SecurityTracker URL:
CVE Reference:   GENERIC-MAP-NOMATCH   (Links to External Site)
Date:  Mar 5 2010
Impact:   Disclosure of authentication information, Disclosure of user information, Execution of arbitrary code via network, Modification of user information
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): 6.0 up to 6.3R7, 6.4R5 and 6.5R2
Description:   A vulnerability was reported in Juniper Instant Virtual Extranet (IVE). A remote user can conduct cross-site scripting attacks.

The Juniper Secure Access (SA) 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 appliance 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.

The 'row' parameter of the bookmark management function (editbk.cgi) is affected.

Niels Heinen of Logica Nederland B.V. reported this vulnerability.

Impact:   A remote user can access the target user's cookies (including authentication cookies), if any, associated with the Instant Virtual Extranet (IVE) device, 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.
Solution:   The vendor has issued a fix (6.3R7, 6.4R5 and 6.5R2).

Subject:  Juniper SA Series Cross Site Scripting Issue

Hash: SHA256


The Juniper Secure Access (SA) web interface allows users to manage the
bookmarks on their landing page. This bookmark management functionality
does not filter user input properly and can allow cross site scripting

Upon modification or creation of a bookmark, the editbk.cgi script is
requested with a parameter named "row".  This parameter identifies the
bookmark in question and its value is used in the server response.  It is a
flaw in the input handling of this "row" parameter that makes the appliance
vulnerable to a cross site scripting attack.

Successful exploitation could allow a remote attacker to hijack an
authenticated session between a victim and the Juniper SA web interface.

Usage of the Single Sign-On (SSO) feature will severely increase the impact
as SSO automatically grants the hijacked session access to other systems
(e.g. typically used in combination with Outlook Web  Access).


Juniper SA appliances running Juniper IVE OS 6.0 or higher


Juniper released IVE updates 6.3R7, 6.4R5 and 6.5R2 which fix this issue.
The updates and installation instructions are available for Juniper
customers on the Juniper website (note: login required)

Alternatively, the bookmark functionality can be temporary disabled until
the Juniper update has been applied. A Juniper administrator can disable
the bookmark functionality via the Central Manager by unchecking the "User
can add bookmarks" option in the "Web" tab of the active user roles.
