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.

|
|
This module abuses the zsudo binary, installed with zpanel, to escalate
|
|
privileges. In order to work, a session with access to zsudo on the sudoers
|
|
configuration is needed. This module is useful for post exploitation of ZPanel
|
|
vulnerabilities, where typically web server privileges are acquired, and this
|
|
user is allowed to execute zsudo on the sudoers file.
