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@xxxxxxxxxxxxxxx
Dominic Beecher dominic@xxxxxxxxxxxxxxx
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.

IGNORES_SHUTDOWN))

host.domain [xx.xx.xx.xx] 1065 (?) open

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
