HP Operations Agent for HP NonStop Server Buffer Overflow in Processing HEALTH Packets Lets Remote Users Execute Arbitrary Code
SecurityTracker Alert ID:  1027429
SecurityTracker URL:
CVE Reference:   GENERIC-MAP-NOMATCH   (Links to External Site)
Date:  Aug 23 2012
Impact:   Execution of arbitrary code via network, User access via network

Description:   A vulnerability was reported in HP Operations Agent for HP NonStop Server. A remote user can execute arbitrary code on the target system.

A remote user can send a specially crafted HEALTH packet to the ELinkService process on TCP ports 7771 or 8976. When the target user checks the status of an existing node on the network, a buffer overflow may occur and arbitrary code may be executed on the target system. The code will run with System privileges.

The vendor was notified on December 22, 2011.

e6af8de8b1d4b2b6d5ba2610cbf9cd38 reported this vulnerability via TippingPoint's Zero Day Initiative.

Impact:   A remote user can execute arbitrary code on the target system.
Solution:   No solution was available at the time of this entry.

ZDI-12-165 : (0Day) HP Operations Agent for NonStop Server HEALTH Packet
Parsing Remote Code Execution Vulnerability
August 22, 2012

- -- CVE ID:

- -- CVSS:
10, AV:N/AC:L/Au:N/C:C/I:C/A:C

- -- Affected Vendors:

- -- Affected Products:
Hewlett-Packard Operations Agent for NonStop

- -- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of HP Operations Agent for NonStop Server. User
interaction is required to exploit this vulnerability in that the target
must check the status of an existing node on the network.

The specific flaw exists within ELinkService process which listens on TCP
ports 7771 and 8976 by default. The process performs insufficient bounds
checking on user-supplied data within in a HEALTH packet prior to copying
it into a fixed-length buffer on the stack. Remote, unauthenticated
attackers can exploit this vulnerability by sending malformed message
packets to the target, which could ultimately lead to arbitrary code
execution under the context of the SYSTEM user.

- -- Vendor Response:
This vulnerability is being disclosed publicly without a patch in
accordance with the ZDI 180 day deadline.
