Hewlett-Packard OVIS Probe Builder Arbitrary Process Termination Vulnerability



Hewlett-Packard's Internet Services provides end-user emulation of major business applications and a single integrated view of the Internet infrastructure. For more information, please visit following URL.


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.

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.


iDefense has confirmed this vulnerability in HP's Internet Services Probe Builder 2.2 for Windows with all updates applied.


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