API Active IDOR Validation
Reference
Remediation
To mitigate Active IDOR vulnerabilities, implement the following security measures:
Indirect Object References: Use indirect object references instead of direct identifiers to prevent predictable ID manipulation.
Authorization Validation: Implement proper authorization checks before allowing access to any resource referenced by an ID.
Session-Based Access Control: Validate that users can only access objects that belong to their session or account.
ID Randomization: Use randomized, non-sequential identifiers to make ID prediction more difficult for attackers.
About
Active IDOR (Insecure Direct Object Reference) validation actively tests for vulnerabilities where applications expose direct references to internal objects. This allows attackers to manipulate parameters to access unauthorized data.
Risks
Active IDOR vulnerabilities can result in:
- Unauthorized access to user data and resources
- Horizontal and vertical privilege escalation
- Data enumeration and information disclosure
- Privacy violations and data breaches
- Manipulation of objects belonging to other users
