Hewlett-Packard OVIS Probe Builder Arbitrary Process Termination


Hewlett-Packard's <http://www.openview.hp.com/products/ovis/index.html>
Internet Services provides "end-user emulation of major business
applications and a single integrated view of the Internet infrastructure".
Remote exploitation of a denial of service vulnerability in
Hewlett-Packard's Internet Services Probe Builder product allows an
unauthenticated attacker the ability to terminate any process.


Vulnerable Systems:
* HP's Internet Services Probe Builder version 2.2 for Windows

The Probe Builder Service, PBOVISServer.exe, listens by default on TCP
port 32968. This process has a specific opcode that allows a remote
unauthenticated user to terminate any process on the system by supplying a
process ID number.

Exploitation allows an attacker to kill any process, including critical
system processes like services.exe, lsass.exe, csrss.exe. Killing a system
process usually results in a blue screen or a mandatory reboot message. To
exploit this vulnerability, the attacker must know the process ID to
terminate. For a remote attacker, it can brute force process ID and cause
the system to crash.

Employing firewalls to limit access to the affected service will mitigate
exposure to this vulnerability.
