Advisory ID: cisco-sa-20080313-ipm
For Public Release 2008 March 13
CiscoWorks Internetwork Performance Monitor (IPM) version 2.6 for Sun
Solaris and Microsoft Windows operating systems contains a
vulnerability that allows remote, unauthenticated users to execute
arbitrary commands. There are no workarounds for this vulnerability.
Cisco has made free software available to address this issue for
This advisory is posted at
IPM version 2.6 for Solaris and Windows operating systems is
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.
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
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
CVSS is a standards-based scoring method that conveys vulnerability

the vulnerability in individual networks.
Cisco has provided an FAQ to answer additional questions regarding
Cisco has also provided a CVSS calculator to help compute the
environmental impact for individual networks at:
* CSCsj06260 - Remote command execution possible using the Process Mgr
CVSS Base Score - 10
Access Vector: Network
Access Complexity: Low
Confidentiality Impact: Complete
Integrity Impact: Complete
Availability Impact: Complete
CVSS Temporal Score - 8.3
Remediation Level: Official-Fix
Report Confidence: Confirmed
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
