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