Date: Mon, 28 Jul 2008 19:30:08 -0400 From: iDefense Labs <labs-no-reply@...fense.com> To: vulnwatch@...nwatch.org, full-disclosure@...ts.grok.org.uk, bugtraq@...urityfocus.com Subject: iDefense Security Advisory 07.28.08: Hewlett-Packard OVIS Probe Builder Arbitrary Process Termination Vulnerability iDefense Security Advisory 07.28.08 http://labs.idefense.com/intelligence/vulnerabilities/ Jul 28, 2008 I. BACKGROUND 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. http://www.openview.hp.com/products/ovis/index.html II. DESCRIPTION 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. III. ANALYSIS 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. IV. DETECTION iDefense has confirmed this vulnerability in HP's Internet Services Probe Builder 2.2 for Windows with all updates applied. V. WORKAROUND Employing firewalls to limit access to the affected service will mitigate exposure to this vulnerability. VI. VENDOR RESPONSE Hewlett-Packard has addressed this vulnerability in the HPSBMA02353 (SSRT080066) security bulletin. For more information, visit the following URL. http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=c01511225 VII. CVE INFORMATION The Common Vulnerabilities and Exposures (CVE) project has assigned the name CVE-2008-1667 to this issue. This is a candidate for inclusion in the CVE list (http://cve.mitre.org/), which standardizes names for security problems. VIII. DISCLOSURE TIMELINE 04/03/2008 Initial vendor notification 05/08/2008 Initial vendor response 07/28/2008 Coordinated public disclosure IX.
