This Metasploit 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.

Zero Day Initiative Advisory 12-101 - This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of IBM Cognos. Authentication is not required to exploit this vulnerability. The flaw exists within the tm1admsd.exe component. This process listens on TCP port 5498 by default. Requests to the service include a request type field, a data length field, and a data field. Multiple request types (opcodes) fail to validate user supplied length and data fields before copying their contents to a fixed length buffer on the stack. A remote attacker can exploit this vulnerability to execute arbitrary code under the context of the system.
