The module first changes the admin e-mail address to prevent any notifications being sent to the actual administrator during the attack, re-enables user registration in case it has been disabled and sets the default role to be administrator. This will allow for the user to create a new account with admin privileges via the default registration page found at /wp-login.php?action=register. ), desc_preformatted: true, author: [ 'Marc-Alexandre Montpas', # Vulnerability discovery 'rastating' # WPXF module ], references: [ ['URL', 'http://blog.sucuri.net/2015/01/security-advisory-vulnerabilities-in-pagelinesplatform-theme-for-wordpress.html'], ['WPVDB', '7762'] ], date: 'Jan 21 2015' ) end
