Descriptions

An issue was discovered in components/com_users/models/registration.php in Joomla! before 3.6.5. Incorrect filtering of registration form data stored to the session on a validation error enables a user to gain access to a registered user's account and reset the user's group mappings, username, and password, as demonstrated by submitting a form that targets the `registration.register` task.

Un problema fue descubierto en components/com_users/models/registration.php en Joomla! en versiones anteriores a 3.6.5. El filtrado incorrecto del registro de los datos guardados en la sesión en un error de validación permite a un usuario ganar acceso a cuentas de usuarios registrados y reiniciar las asignaciones de grupo del usuario, el nombre de usuario y contraseña como se demuestra mediante la presentación de un formulario que se dirige a la tarea `registration.register`.
