CiscoWorks Input Validation Hole in Login Page Permits Cross-Site Scripting Attacks
SecurityTracker Alert ID:  1019043
SecurityTracker URL:  http://securitytracker.com/id/1019043
CVE Reference:   CVE-2007-5582   (Links to External Site)
Date:  Dec 5 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): Common Services 3.0.x, 3.1
Description:   A vulnerability was reported in CiscoWorks. A remote user can conduct cross-site scripting attacks.

The login page 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 CiscoWorks 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.

The vendor was notified on September 24, 2007.

Cisco has assigned Cisco bug ID CSCsk69289 to this vulnerability.

CiscoWorks Common Management Foundation is not affected.

CiscoWorks products that do not use CiscoWorks Common Services are not affected.

Dave Lewis of Liquidmatrix.org 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 CiscoWorks 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.

without performing any validity checks to
