The second connection utilizes the data from the data leak to accurately exploit the stack based buffer overflow vulnerability. Props to Infamous41d for helping in finding this exploitation path. ![]() ![]() Using this data allows for reliable exploitation of the buffer overflow vulnerability. By supplying a large value for this argument it is possible to cause Timbuktu to reply to the initial request with leaked stack data. The first connection is used to leak stack data using the buffer overflow to overwrite the nNumberOfBytesToWrite argument. This module exploits a stack based buffer overflow in Timbuktu Pro version <= 8.6.6 in a pretty novel way. ![]()
