-- 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 flaw exists within the ovutil.dll component which is loaded by the
webserver listening by default on TCP port 80. When handling the COOKIE
variable passed through a GET request, the process blindly copies user
supplied data into a fixed-length buffer on the stack. A remote attacker
can exploit this vulnerability to execute arbitrary code under the
context of the SYSTEM service.
