Mass assignment leading to creation of admin role

Mass assignment leading to creation of admin role

The endpoint appears to be vulnerable to Mass Assignment attack. The original request was replayed by adding role with admin permissions in request body. The application responded with 2XX success code in response.

Mass Assignment (MA)

"The endpoint appears to be vulnerable to Mass Assignment attack. The original request was replayed by adding role with admin permissions in request body. The application responded with 2XX success code in response. <b>Background:</b> Objects in modern applications might contain many properties. Some of these properties should be updated directly by the client (e.g., user.first_name or user.address) and some of them should not (e.g., user.is_vip flag).\n" "An API endpoint is vulnerable if it automatically converts client parameters into internal object properties, without considering the sensitivity and the exposure level of these properties. This could allow an attacker to update object properties that they should not have access to.\n" "Examples for sensitive properties: Permission-related properties: user.is_admin, user.is_vip should only be set by admins. Process-dependent properties: user.cash should only be set internally after payment verification. Internal properties: article.created_time should only be set internally by the application."

How this template works

APIs Selection

The template uses API selection filters to specify the criteria for selecting the API endpoints to test. It filters the endpoints based on the response code (between 200 and 299), the HTTP method (PUT, POST, or PATCH), and the URL containing the word "user". It also checks if the request payload contains either the "email" or "login" key, and if the response payload contains the "role" key.

Execute request

The template executes a single request by adding a body parameter to the request. In this case, it adds the "role" parameter with the value "admin" to the request body.

Validation

The template validates the response by checking if the response code is between 200 and 299, and if the response payload contains the string "admin". If both conditions are met, the validation is considered successful.
