Revision 1.0

For Public Release 2008 March 13

Summary
=======

CiscoWorks Internetwork Performance Monitor (IPM) version 2.6 for Sun

This advisory is posted at
http://www.cisco.com/warp/public/707/cisco-sa-20080313-ipm.shtml.

Affected Products
=================

Vulnerable Products
+------------------

IPM version 2.6 for Solaris and Windows operating systems is
vulnerable.

Products Confirmed Not Vulnerable
+--------------------------------

IPM versions 2.5 and earlier as well as IPM version 4.0 are not
vulnerable. No other Cisco products are known to be vulnerable.

Details
=======

CiscoWorks IPM is a troubleshooting application that gauges network
response time and availability. It is available as a component within
the CiscoWorks LAN Management Solution (LMS) bundle. IPM version 2.6
for Solaris and Windows contains a process that causes a command
shell to automatically be bound to a randomly selected TCP port.
Remote, unauthenticated users are able to connect to the open port
and execute arbitrary commands with casuser privileges on Solaris
systems and with SYSTEM privileges on Windows systems. This
vulnerability is documented in CVE-2008-1157 and Cisco Bug ID 
CSCsj06260.

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: 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: http://intellishield.cisco.com/security/alertmanager/cvss * CSCsj06260 - Remote command execution possible using the Process Mgr CVSS Base Score - 10 Access Vector: Network Access Complexity: Low Authentication: None Confidentiality Impact: Complete Integrity Impact: Complete Availability Impact: Complete CVSS Temporal Score - 8.3 Exploitability: Functional Remediation Level: Official-Fix Report Confidence: Confirmed Impact ====== Successful exploitation of the vulnerability may result in the ability to execute arbitrary commands with the non-privileged casuser user account on Solaris systems and with full administrative SYSTEM privileges on Windows systems. Software Versions and Fixes
When considering software upgrades, also consult http://www.cisco.com/go/psirt and any subsequent advisories to determine exposure and a complete upgrade solution. This vulnerability is corrected in the IPM version 2.6 CSCsj06260 patch for Solaris and Windows operating systems. Fixed software can be obtained here: http://www.cisco.com/pcgi-bin/tablebuild.pl/ipm-sol?psrtdcat20e2 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 =========== There are no workarounds for this vulnerability. It is possible to mitigate this vulnerability by restricting network access to TCP ports on a system running IPM version 2.6 to trusted systems. Administrators are strongly encouraged to upgrade to a fixed version of IPM. 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: http://www.cisco.com/warp/public/707/cisco-amb-20080313-ipm.shtml Obtaining Fixed Software
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. Customers may only install and expect support for the feature sets they have purchased. By installing, downloading, accessing or otherwise using such software upgrades, customers agree to be bound by the terms of Cisco's software license terms found a http://www.cisco.com/en/US/products/prod_warranties_item09186a008088e31f.html, or as otherwise set forth at Cisco.com Downloads at http://www.cisco.com/public/sw-center/sw-usingswc.shtml. Do not contact [email protected] or [email protected] for software upgrades. 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: [email protected] 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.
