BOLA by HTTP Parameter Pollution

BOLA by HTTP Parameter Pollution

Attacker can access resources of any user by introducing multiple parameters with same name.

Broken Object Level Authorization (BOLA)

"The endpoint appears to be vulnerable to broken object level authorization attack. The original request was replayed by adding private resources in query params (for eg: <b>user_id=1234&account_id=436783).</b>. The server responded with 2XX success codes and less than <b>{{percentageMatch}}%</b> of the response body matched with original response body. <br><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."

Impact of the vulnerability

Impact of the vulnerability

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 desired API requests. In this case, it filters requests based on the response code being between 200 and 300, and the presence of a private variable context with a value greater than 0.

Execute request

The template executes a single request using the private variable extracted from the private variable context. It adds the private variable as a query parameter in the request.

Validation

The template validates the response received from the executed request. It checks that the response code is between 200 and 300, and the percentage match of the response payload is less than 80%. Additionally, it ensures that the response payload has a length greater than 0.
