IDOR by adding user id in query params

IDOR by adding user id in query params

Attacker can access resources of any user by adding user_id in URL.

Broken Object Level Authorization (BOLA)

Business Logic

"The endpoint appears to be vulnerable to broken object level authorization attack. The original request was replayed by adding other user's user id in query params. The server responded with 2XX success codes and less than <b>{{percentageMatch}}%</b> of the response body matched with original response body. <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 API requests to be executed. In this case, the filters include checking the response code to be between 200 and 300, and extracting the value of the "user" or "customer" parameter as the "user_context" for further use.

Execute request

The template uses a single request execution type, which means it will execute a single API request. The request is defined using the "add_query_param" action, where the value of the "user_context.key" is set to the extracted value from the API selection filters.

Validation

After executing the request, the template performs validation on the response. It checks that the response code is between 200 and 300, and also checks the response payload for two conditions. Firstly, it checks that the percentage match of the response payload with the original response payload is less than 50%. Secondly, it checks that the length of the response payload is greater than 0.
