|
|
This module takes advantage of a file privilege misconfiguration problem
|
|
specifically against Windows MySQL servers (due to the use of a .mof file).
|
|
This may result in arbitrary code execution under the context of SYSTEM. However,
|
|
please note in order to use this module, you must have a valid MySQL account on
|
|
the target machine.
