BOLA by changing auth token

BOLA by changing auth token

Attacker can access resources of any user by changing the auth token in request.

Broken Object Level Authorization (BOLA)

"The endpoint appears to be vulnerable to broken object level authorization attack. The original request was replayed with attacker's auth token. The server responded with 2XX success codes and greater than <b>{{percentageMatch}}%</b> of the response body matched with original response body. Also, the endpoint had atleast one private resources in request payload.<br>" "<b>Background:</b> Object level authorization is an access control mechanism that is usually implemented at the code level to validate that one user can only access objects that they should have access to. Unauthorized access can result in data disclosure to unauthorized parties, data loss, or data manipulation. Unauthorized access to objects can also lead to full account takeover."

Unauthorized access can result in data disclosure to unauthorized parties, data loss, or data manipulation. Unauthorized access to objects can also lead to full account takeover.

How this template works

APIs Selection

The template uses API selection filters to specify the criteria for selecting the API requests to be executed. In this case, the filters include checking the response code to be between 200 and 300, and the presence of at least one private variable in the request payload.

Execute request

The template specifies the execution type as "single", which means that only one request will be executed. The request includes a step to replace the authentication header with a new token. This allows the attacker to replay the original request with their own token.

Validation

The template defines validation criteria for the response. It checks that the response code is between 200 and 300, the response payload has a length greater than 0, and the percentage match between the response body and the original response body is at least 90%. These validations ensure that the attack was successful and the server responded as expected.
