(0Day) HP Operations Agent for NonStop Server HEALTH Packet Parsing Remote
Code Execution Vulnerability
ZDI-12-165: August 22nd, 2012
Operations Agent for NonStop
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.
This vulnerability is being disclosed publicly without a patch in accordance
with the ZDI 180 day deadline.
