Descriptions

Versions up to, and including, 5.4.3, of the Booster for WooCommerce WordPress plugin are vulnerable to authentication bypass via the process_email_verification function due to a random token generation weakness in the reset_and_mail_activation_link function found in the ~/includes/class-wcj-emails-verification.php file. This allows attackers to impersonate users and trigger an email address verification for arbitrary accounts, including administrative accounts, and automatically be logged in as that user, including any site administrators. This requires the Email Verification module to be active in the plugin and the Login User After Successful Verification setting to be enabled, which it is by default.

Las versiones hasta 5.4.3, incluyéndola, del plugin Booster for WooCommerce para WordPress, son vulnerables a una omisión de la autenticación por medio de la función process_email_verification debido a una debilidad en la generación de tokens aleatorios en la función reset_and_mail_activation_link que se encuentra en el archivo ~/includes/class-wcj-emails-verification.php. Esto permite a atacantes suplantar a usuarios y desencadenar una comprobación de la dirección de correo electrónico para cuentas arbitrario, incluyendo cuentas administrativas, y automáticamente iniciar sesión como ese usuario, incluyendo cualquier administrador del sitio. Esto requiere que el módulo de Comprobación de Correo Electrónico esté activo en el plugin y que la configuración de Inicio de Sesión del Usuario Después de la comprobación Exitosa esté habilitada, lo cual es por defecto.
