http://www.cisco.com/warp/public/707/cisco-sr-20071205-cw.shtml

Revision 1.0

For Public Release 2007 December 05 1600 UTC (GMT)

- ---------------------------------------------------------------------

Cisco Response
==============

This is the Cisco PSIRT response to an issue that was discovered and
reported to Cisco by David Lewis of Liquidmatrix.org regarding a
cross-site scripting (XSS) vulnerability in CiscoWorks Server login
page.

The original report is available at the following link:
http://www.liquidmatrix.org/blog/2007/12/05/advisory-cross-site-scripting-in-ciscoworks/

We greatly appreciate the opportunity to work with researchers on
security vulnerabilities and welcome the opportunity to review and
assist in product reports.

This vulnerability is documented in Cisco bug ID CSCsk69289.

This Cisco Security Response is posted at the following link:
http://www.cisco.com/warp/public/707/cisco-sr-20071205-cw.shtml

This vulnerability has been assigned CVE ID CVE-2007-5582.

Additional Information
======================

CiscoWorks Common Services (CS) provides the foundation of
application infrastructure for all existing CiscoWorks network
management solutions to share a common model for data storage, user
login, user role definitions, user access privileges, and security
protocols.

CS is vulnerable to Cross Site Scripting (XSS) attacks from the
CiscoWorks Server login page, http://server-name:portnumber. In both
Windows and Solaris, the port numbers are 1741 for normal access, and
the secure port number is 443. Both the Windows and Solaris versions
of the Cisco Works Server login page are affected.

When this XSS vulnerability is exploited, malicious code or script is
embedded within the URL and associated with an unsuccessful login
attempt page refresh.

The malicious code typically takes the form of a script that is
embedded within the URL of a link. The malicious code may also be
stored on the vulnerable server or a malicious website. An attacker
could try to convince an unsuspecting user to follow a malicious link
to a vulnerable CiscoWorks server that injects (reflects) the
malicious code into the user's browser.

The following versions of CiscoWorks Common Services for both Solaris
and Windows operating systems are affected by this vulnerability:

   * CiscoWorks Common Services 3.0.x
   * CiscoWorks Common Services 3.1

Prior to CiscoWorks Common Services 3.0, the product was titled
CiscoWorks Common Management Foundation (CMF). CMF is not affected by
this vulnerability.

CiscoWorks products that do not use CiscoWorks Common Services are
not affected by this vulnerability.

Workarounds
===========

There are no known workarounds for this vulnerability. Cisco
recommends applying a point patch to address the vulnerability. The
point patch can be downloaded from Cisco.com for both Solaris and
Windows Operating Systems at:
http://www.cisco.com/cgi-bin/tablebuild.pl/cw2000-cd-one ( registered 
customers only) .

exploit these vulnerabilities, please refer to the Cisco Applied
Mitigation Bulletin "Understanding Cross-Site Scripting (XSS) Threat
Vectors", which is available at the following link:
