'Description' => %q{
|
||||
This module exploits a vulnerability found in ZPanel's htpasswd module. When
|
||||
creating .htaccess using the htpasswd module, the username field can be used to
|
||||
inject system commands, which is passed on to a system() function for executing
|
||||
the system's htpasswd's command.
|
||||
|
||||
Please note: In order to use this module, you must have a valid account to login
|
||||
to ZPanel. An account part of any of the default groups should suffice, such as:
|
||||
Administrators, Resellers, or Users (Clients). By default, there's already a
|
||||
'zadmin' user, but the password is randomly generated.
