Advanced IDORs - 9 Techniques by @intigriti: 1. Exploiting Basic IDORs How to: Modify a predictable numeric ID in the request URL or parameters. Example: GET /user/email?userId=1002 (change userId to another value). 2. Exploiting IDORs via Parameter Pollution How to: Inject multiple instances of the same parameter in the request. Example: POST /update_profile with user_id=1234&user_id=5678. 3. Exploiting IDORs via JSON Globbing How to: Manipulate JSON fields with arrays, booleans, wildcards, or large integers. Example: { "user_id": ["1234", "5678"] } or { "user_id": "*" }. 4. Exploiting Method-Based IDORs How to: Change the HTTP method to bypass access controls. Example: Change GET /user/data to POST /user/data. 5. Exploiting Content-Type-Based IDORs How to: Alter the Content-Type header to manipulate request processing. Example: Use Content-Type: application/json instead of Content-Type: text/plain. 6. Exploiting IDORs via Deprecated API Versions How to: Use older API versions that may lack updated security checks. Example: Access /v1/user/data instead of /v2/user/data. 7. Exploiting IDORs in APIs that Use Static Keywords How to: Replace keywords like current or me with numerical user IDs. Example: Change /user/profile/current to /user/profile/1002. 8. Exploiting IDORs that Require Unpredictable IDs How to: Find references to UUIDs or hashes in other parts of the application. Example: Extract UUID from profile URLs like /profile/123e4567-e89b-12d3-a456-426614174000. 9. Exploiting Second-Order IDOR Vulnerabilities How to: Manipulate stored IDs used in subsequent processes. Example: Submit a form that stores your ID, then trigger an export process that retrieves data using that stored ID. ---------------------------------------------------------- I've never seen real-world examples for some of them, but they are definitely worth the try. #pentesting #appsec #bugbounty #cybersecurity Here's the full scoop: buff.ly/3zfhhzL
