There are many plugins available to upload images and process them (crop, resize etc) in CakePHP, check this list https://github.com/FriendsOfCake/awesome-cakephp#imagery and https://github.com/FriendsOfCake/awesome-cakephp#files. Then you'll need to extend the CakeDC Users Plugin to attach the upload related behavior, follow the documentation to extend the Users Table here https://github.com/CakeDC/users/blob/master/Docs/Documentation/Extending-the-Plugin.md#extending-the-model-tableentity
Note this will depend a lot on the upload plugin selected, but most of them will provide a behavior you'll need to attach to the Users Table.
Then override the users edit/add templates to add the required file fields for the avatar image upload.
