Revision 1.0

For Public Release 2010 January 20 16:00  UTC (GMT)


Summary

CiscoWorks Internetwork Performance Monitor (IPM) versions 2.6 and earlier for Microsoft Windows operating systems contain a buffer overflow vulnerability that could allow a remote unauthenticated attacker to execute arbitrary code. There are no workarounds for this vulnerability.

This advisory is posted at http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20100120-ipm.

Affected Products

Vulnerable Products

CiscoWorks IPM versions 2.6 and earlier for Windows operating systems are affected.

Products Confirmed Not Vulnerable

CiscoWorks IPM version 2.x for Sun Solaris and CiscoWorks IPM version 4.x for Windows and Solaris operating systems are not affected. No other Cisco products are currently known to be affected by this vulnerability.

Details

CiscoWorks IPM is a troubleshooting application that gauges network response time and availability. CiscoWorks IPM is available as a component within the CiscoWorks LAN Management Solution (LMS) bundle. CiscoWorks IPM versions 2.6 and earlier for Windows contain a buffer overflow vulnerability when processing Common Object Request Broker Architecture (CORBA) GIOP requests. By sending a crafted CORBA GIOP request, a remote, unauthenticated attacker may be able to trigger the buffer overflow condition and execute arbitrary code with SYSTEM privileges on affected Windows systems. This vulnerability is documented in Cisco Bug ID CSCsv62350 and has been assigned the Common Vulnerabilities and Exposures (CVE) CVE-2010-0138.

Vulnerability Scoring Details

Cisco has provided scores for the vulnerabilities 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:

Impact

Successful exploitation of the vulnerability may result in the ability to execute arbitrary code with SYSTEM privileges on affected Windows systems.

Software Versions and Fixes

Ciscoworks IPM versions 2.6 and earlier for Windows contain a vulnerable third-party component that is no longer supported. Cisco is unable to provide updated software for affected CiscoWorks versions. Consult the Obtaining Fixed Software section of this advisory for instructions on how to address vulnerable systems.


Workarounds

There are no workarounds for this vulnerability. It is possible to mitigate this vulnerability by restricting network access to TCP ports on an affected Windows system running IPM versions 2.6 and earlier to trusted systems.

Additional mitigation techniques that can be deployed on Cisco devices within the network are available in the Cisco Applied Mitigation Bulletin companion document for this advisory:

Obtaining Fixed Software

Ciscoworks IPM versions 2.6 and earlier for Windows contain a vulnerable third-party component that is no longer supported. Cisco is unable to provide updated software for affected CiscoWorks versions.

Customers with active software licenses for the IPM component of CiscoWorks versions 2.6 and earlier for Windows should send email to the following address for instructions on migrating to non-vulnerable software:

ipm-corba-fix@cisco.com

Customers with Service Contracts

Customers with contracts should obtain upgraded software through their regular update channels. For most customers, this means that upgrades should be obtained through the Software Center on Cisco's worldwide website at http://www.cisco.com.

Customers Using Third-Party Support Organizations

Customers whose Cisco products are provided or maintained through prior or existing agreements with third-party support organizations, such as Cisco Partners, authorized resellers, or service providers should contact that support organization for guidance and assistance with the appropriate course of action in regards to this advisory.

The effectiveness of any workaround or fix is dependent on specific customer situations, such as product mix, network topology, traffic behavior, and organizational mission. Due to the variety of affected products and releases, customers should consult with their service provider or support organization to ensure any applied workaround or fix is the most appropriate for use in the intended network before it is deployed.

Customers Without Service Contracts

Customers who purchase direct from Cisco but do not hold a Cisco service contract, and customers who purchase through third-party vendors but are unsuccessful in obtaining fixed software through their point of sale should acquire upgrades by contacting the Cisco Technical Assistance Center (TAC). TAC contacts are as follows.

  • +1 800 553 2447 (toll free from within North America)
  • +1 408 526 7209 (toll call from anywhere in the world)
  • e-mail: tac@cisco.com

Customers should have their product serial number available and be prepared to give the URL of this notice as evidence of entitlement to a free upgrade. Free upgrades for non-contract customers must be requested through the TAC.
