Vulnerability Scoring Details

Cisco has provided scores for the vulnerability in this advisory based on the Common Vulnerability Scoring System (CVSS). The CVSS scoring in this Security Advisory is done in accordance with CVSS version 2.0.

CVSS is a standards-based scoring method that conveys vulnerability severity and helps determine urgency and priority of response.

Cisco has provided a base and temporal score. Customers can then compute environmental scores to assist in determining the impact of the vulnerability in individual networks.

Cisco has provided an FAQ to answer additional questions regarding CVSS at

http://www.cisco.com/web/about/security/intelligence/cvss-qandas.html.

Cisco has also provided a CVSS calculator to help compute the environmental impact for individual networks at

Software Versions and Fixes

Cisco has released free software updates that address these vulnerabilities. Prior to deploying software, customers should consult their maintenance provider or check the software for feature set compatibility and known issues specific to their environment.

This vulnerability has been corrected in CiscoWorks Common Services version 3.2 and in the following software patches:

cwcs3.x-sol-CSCsm77245-0.tar.gz - for Solaris versions

cwcs3.x-win-CSCsm77245-0.zip - for Windows versions

The CiscoWorks Common Services patches can be downloaded from:

http://www.cisco.com/pcgi-bin/tablebuild.pl/cw2000-cd-one

When considering software upgrades, also consult http://www.cisco.com/go/psirt and any subsequent advisories to determine exposure and a complete upgrade solution.

In all cases, customers should exercise caution to be certain the devices to be upgraded contain sufficient memory and that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, contact the Cisco Technical Assistance Center (TAC) or your contracted maintenance provider for assistance.

Workarounds

Filters such as Transit ACLs (tACLs) can be used to allow access to the Administration Workstation from only trusted hosts.

Filters that deny HTTP packets using HTTPS packets using TCP port 443 and TCP port 1741 should be deployed throughout the network as part of a tACL policy to protect the network from traffic that enters the network at ingress access points. This policy should be configured to protect the network device where the filter is applied and other devices that are behind it. Filters for HTTPS packets that use TCP port 443 and TCP port 1741 should also be deployed in front of vulnerable network devices so only traffic from trusted clients is allowed.

Note:  Additional information about tACLs is available in "Transit Access Control Lists: Filtering at Your Edge: http://www.cisco.com/en/US/tech/tk648/tk361/technologies_white_paper09186a00801afc76.shtml.
