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 ( registered customers only) .
-
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:
