HP OpenView Radia Management Agent remote command execution via directory traversal

NGSSoftware Insight Security Research Advisory

Name: HP OpenView Radia Management Agent remote command execution via
directory traversal
Systems Affected: HP OpenView Radia Management Portal versions 2.x and
1.x running Radia Management Agent
Severity: High
Vendor URL: http://www.hp.com/
Authors: David Morgan      davidm () ngssoftware com

Date of initial advisory:  28 April 2005
Date of full advisory:     28 July 2005

Description
-----------

The Radia Management Agent is part of HP's OpenView Radia suite of
software. It runs as a Windows service (RMA) with Local System
privileges. The RMA service listens on a TCP port that is not fixed. In
the example below, the service was listening on TCP port 1065.

By connecting to the TCP port and sending a crafted packet, it is
possible to traverse out of C:\Program Files\Novadigm (the apparent
working directory) and run any executable that is located on the same
logical disk partition, in this case the C: drive.

        WAIT_HINT          : 0x0

        FLAGS              :

xx.xx.xx.xx 1065

host.domain [xx.xx.xx.xx] 1065 (?) open
nt authority\system

The output from whoami.exe clearly demonstrates that it is possible for
a remote attacker to execute arbitrary system commands with Local System
privileges without authentication.

Fix Information
---------------

HP has developed a patch to fix the problem. More information can be
