This Metasploit module exploits a stack based buffer overflow in Timbuktu Pro version <= 8.6.6 in a pretty novel way. This exploit requires two connections. The first connection is used to leak stack data using the buffer overflow to overwrite the nNumberOfBytesToWrite argument. By supplying a large value for this argument it is possible to cause Timbuktu to reply to the initial request with leaked stack data. Using this data allows for reliable exploitation of the buffer overflow vulnerability. Props to Infamous41d for helping in finding this exploitation path. The second connection utilizes the data from the data leak to accurately exploit the stack based buffer overflow vulnerability. TODO: hdm suggested using meterpreter's migration capability and restarting the process for multishot exploitation.
1a3eb49398ce9b0ab57cd1e8f8fcef3eb6dad5ad3499db7694e64b4fa58552a2iDefense Security Advisory 06.25.09 - Remote exploitation of a stack-based buffer overflow vulnerability in Motorola Inc.'s Timbuktu Pro could allow attackers to execute arbitrary code with SYSTEM privileges. Timbuktu fails to properly handle user-supplied data passed through a named pipe session. When the PlughNTCommand named pipe receives an overly large character string, a buffer overflow will occur resulting in arbitrary code execution. iDefense has confirmed the existence of this vulnerability in Timbuktu Pro version 8.6.5. Previous versions may also be affected.
