|
|
This module generates an Apache OpenOffice Text Document with a malicious macro in it.
|
|
For exploit successfully, the targeted user must adjust the security level in Macro
|
|
Security to either Medium or Low. If set to Medium, a prompt is presented to the user
|
|
to enable or disable the macro. If set to Low, the macro can automatically run without
|
|
any warning.
|
|
|
|
The module also works against LibreOffice.
