In this honest and educational write-up, the author explains what an IDOR vulnerability is and how it can be exploited by using a real-world example from a hacking simulation website called TryHackMe.
To start, the author outlines that an IDOR stands for Insecure Direct Object Reference, which is a type of access control vulnerability that can occur when a web server retrieves objects without sufficiently validating the user’s identity.
The author then walks through a practical example of an IDOR on the Try Hack Me website, where participants are tasked with identifying and exploiting an IDOR vulnerability and retrieving a flag.
Along the way, the author provides insightful tips on identifying categorical IDs and using decoding and hashing techniques to manipulate ID parameters.
The summary concludes with the author encouraging readers to learn more about IDOR vulnerabilities and thanking them for their interest.
Overall, the walkthrough educationally provides a thorough explanation of IDOR vulnerabilities and demonstrates a practical example of exploitation for educational purposes.
