8 Steps to Uncovering Insecure Direct Object References for Bug Bounty Hunters

Insecure Direct Object References (IDOR) is a type of vulnerability that occurs when an application uses a direct object reference to access sensitive information. This can allow an attacker to access information that they should not have access to. In this article, we will discuss how to test for IDOR vulnerabilities and provide examples of payloads that can be used to exploit them.

Testing for IDOR vulnerabilities can be done by capturing the request, filtering the parameters, and tampering with them. The most widely used tool for this type of attack is Burp Suite. The following are the steps involved in executing an IDOR attack:

1. Capture the Request
   The first step in testing for IDOR vulnerabilities is to capture the request. This can be done using Burp Suite’s proxy feature.
2. Filter the Parameters Request
   Once the request has been captured, the next step is to filter the parameters. This can be done by looking for parameters that are used to retrieve a database record, perform an operation in the system, retrieve a file system resource, or access application functionality.
3. Forward Request to Repeater
   After filtering the parameters, the next step is to forward the request to the Repeater tool. This tool allows you to tamper with the…
