'Name' => 'IBM Cognos tm1admsd.exe Overflow',
'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.
