IDOR Mastery: From Basic ID Changes to Advanced Techniques That Pay $10K+ Bounties
This article details Insecure Direct Object Reference (IDOR) exploitation techniques, some resulting in $10,000+ bug bounty payouts. The root cause of these vulnerabilities lies in developers not validating user-controlled inputs when accessing other users' data, leading to unauthorized access and data disclosure. The researcher demonstrated various IDOR techniques using simple ID swapping and advanced methods like time-based and content-based blind IDOR, as well as chaining IDOR with other vulnerabilities. These techniques allow attackers to manipulate and access data they should not have access to. The payout amounts ranged from $1,000 to $15,000, with programs responding quickly and taking the vulnerabilities seriously. Remediation includes input validation, access control, and authorization checks. Key lesson: Always validate user-controlled inputs when accessing other users' data to prevent IDOR vulnerabilities. #BugBounty #WebSecurity #IDOR #Cybersecurity #InputValidation -
