Understanding IDOR: The Million-Dollar Bug

In the world of cybersecurity, Insecure Direct Object References (IDOR) are extremely valuable security bugs that are worth comprehensively understanding. This article will delve into how IDOR works and its staggering potential impact.

How Does IDOR Work?

IDOR vulnerabilities occur when an application provides direct access to objects based on user-supplied input. This means that possessing a specific URL, for example, could allow you to perform actions that you are not authorized to perform.

For instance, consider this example where access to a particular URL allows the creation of new secondary users on a PayPal business account, even if you do not own the account. Such a vulnerability could have severe implications for the affected service.

Why is IDOR Valuable?

The payout for discovering and reporting an IDOR vulnerability tends to be massive, often due to the high impact it can have. In the case of our example, the payout could be as much as $ 10,000. This high potential reward is part of the reason why IDOR vulnerabilities frequently appear on job descriptions and arise during interviews for security-related roles.

Conclusion

Understanding and identifying IDOR vulnerabilities is absolutely critical for anyone involved in cybersecurity, whether they are bug bounty hunters or security professionals. Not only does this knowledge contribute to better overall security, but it also opens the door to substantial financial rewards.
