-- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of Hewlett-Packard OpenView Network Node
Manager. Authentication is not required to exploit this vulnerability.

The specific flaw exists within the ovwebsnmpsrv.exe process which can
be reached remotely through the jovgraph.exe CGI program. When the
ovwebsnmpsrv.exe process is started a function responsible for parsing
command line arguments does not properly handle unrecognized options. By
supplying an overly large unrecognized option through an HTTP request
the error handling functionality can be made to overflow a static buffer
while creating the error message. An attacker can leverage this to
execute arbitrary code under the context of the user running the
webserver.

-- Vendor Response:
Hewlett-Packard has issued an update to correct this vulnerability. More
