Rails Mass Assignment

Synopsis

Rails Mass Assignment

Description

Ruby On Rails is a popular framework used to build web applications based on the Model-View-Controller (MVC) architectural pattern.

A mass assignment vulnerability occurs when an application automatically performs the mapping between a request parameters and a model attributes. This vulnerability can be leveraged by an attacker to modify internal attributes which should not be exposed to the end user and can have multiple impacts depending on the application logic like the gain of privileges or the leak of sensitive information.

Solution

The application should control the access to the attributes by using an explicit allowlist of parameters through the attr_accessible method.
