Red Hat Network Satellite Server Input Validation Hole Permits Cross-Site Scripting Attacks
SecurityTracker Alert ID:  1026391
SecurityTracker URL:  http://securitytracker.com/id/1026391
CVE Reference:   CVE-2011-4346   (Links to External Site)
Date:  Dec 8 2011
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): 5.4.1
Description:   A vulnerability was reported in Red Hat Network Satellite Server. A remote authenticated user can conduct cross-site scripting attacks.

The web interface does not properly filter HTML code from user-supplied input before displaying the input. A remote authenticated user can cause arbitrary scripting code to be executed by the target authenticated user's browser. The code will originate from the site running the Red Hat Network Satellite Server 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.

William Hoffmann reported this vulnerability.

Impact:   A remote authenticated user can access the target user's cookies (including authentication cookies), if any, associated with the site running the Red Hat Network Satellite Server 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 a fix.
