Blue Coat ProxySG Management Console Input Validation Hole in Processing CRLs Permits Cross-Site Scripting Attacks
SecurityTracker Alert ID:  1018888
SecurityTracker URL:  http://securitytracker.com/id/1018888
CVE Reference:   CVE-2007-5796   (Links to External Site)
Updated:  Feb 18 2008
Original Entry Date:  Nov 2 2007
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): 4.x prior to 4.2.6.1, 5.x prior to 5.2.2.5
Description:   A vulnerability was reported in Blue Coat ProxySG. A remote user can conduct cross-site scripting attacks.

The management console 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 site running the Blue Coat ProxySG software 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.

Adrian Pastor of ProCheckUp reported this vulnerability.

Impact:   A remote user can access the target user's cookies (including authentication cookies), if any, associated with the site running the Blue Coat ProxySG software, 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 fixed versions (4.2.6.1, 5.2.2.5).
