What are the two main types of IDOR vulnerabilities this skill covers?

The skill covers direct database-object references (e.g., ?id=2023 vs ?id=2022) and direct static-file references (e.g., /static/receipt/205.pdf vs /200.pdf).

What prerequisites do I need before testing for IDOR vulnerabilities?

You need a target application URL with user-specific resources, at least two test accounts, a Burp Suite or proxy tool, written authorization, and an understanding of how objects are referenced (IDs, filenames).

What are the three main detection techniques for finding IDOR vulnerabilities?

The three techniques are URL parameter manipulation (swap an authenticated request's ID to another user's), request body manipulation (change a userId field in a POST/PUT), and HTTP method switching (try GET as POST or PUT if blocked with 403).

How does Burp Suite help with IDOR exploitation?

Burp Suite enables manual interception and ID substitution, automated Sniper-attack enumeration via Intruder with numeric range payloads to scan for 200 responses, and Battering Ram attacks when the same ID appears in multiple request positions.

What is the key remediation strategy shown in the Django code examples?

The skill recommends verifying resource ownership before updates (e.g., if address.user != request.user), using indirect references scoped to the authenticated user instead of raw IDs, and always filtering server-side queries by user=request.user rather than trusting client-supplied IDs.

Overview

IDOR Vulnerability Testing

This skill delivers systematic methodologies for identifying and exploiting Insecure Direct Object Reference (IDOR) vulnerabilities in web applications. It covers detection techniques using parameter manipulation and enumeration for both database object references and static file references, exploitation via Burp Suite, and remediation strategies for securing applications against unauthorized access. Use this when conducting security assessments of web applications that expose direct object references in URLs or API parameters, during penetration testing engagements requiring systematic enumeration of access control flaws, or when implementing security reviews for applications with database records or file paths that may be vulnerable to unauthorized access.

What it does

This skill provides systematic methodologies for identifying and exploiting Insecure Direct Object Reference (IDOR) vulnerabilities in web applications. It covers both database object references and static file references, offering detection techniques through parameter manipulation and enumeration, exploitation via Burp Suite, and remediation strategies to secure applications against unauthorized access.

When to use - and when NOT to

Use this skill when conducting security assessments of web applications that use direct object references in URLs or API parameters, when testing for unauthorized access to resources through ID manipulation, or when implementing security reviews for applications that expose database records or file paths. Use it during penetration testing engagements where you need to systematically enumerate and test object reference parameters.

Do NOT use this skill on production systems without explicit authorization and proper legal agreements in place. Do NOT use it for malicious purposes or unauthorized access attempts, as IDOR exploitation without permission is illegal and unethical.

Inputs and outputs

You provide web application endpoints that use object references (database IDs, file paths, or other direct references), authentication credentials for legitimate access testing, and the scope of parameters to test. The skill guides you through parameter identification, manipulation techniques, and enumeration strategies.

You receive systematic testing methodologies for detecting IDOR vulnerabilities, exploitation techniques for validating unauthorized access, and remediation strategies for securing applications.

Integrations

Burp Suite is the primary tool integration for intercepting requests, manipulating parameters, and automating enumeration of object references during IDOR testing workflows.

Who it's for

This skill is designed for penetration testers conducting web application security assessments and security professionals who need structured testing methodologies for identifying and exploiting IDOR vulnerabilities in authorized engagements.
