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 (registered customers only) .

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/pcgi-bin/tablebuild.pl/cw2000-cd-one (registered customers only) .
