-- 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 snmp.exe CGI executable accessible
via the IIS web server listening by default on TCP port 80. While
parsing POST variables this process copies the contents of the Oid
parameter into a fixed length stack buffer using a sprintf() call. By
supplying a large enough value this buffer can be overflowed leading to
arbitrary code execution.

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