CWE-285

What is CWE-285 (Improper Authorization)?

The product does not perform or incorrectly performs an authorization check when an actor attempts to access a resource or perform an action.

Vulnerability Insights

Improper Authorization (CWE-285) represents a security risk across modern software systems. This weakness enables attackers to exploit access control flaws, potentially leading to unauthorized access, data exfiltration, or system compromise. Organizations should implement defense-in-depth strategies combining static analysis, runtime monitoring, and binary analysis.

Impact on Systems

• Horizontal Privilege Escalation: Accessing other users' resources
• Vertical Privilege Escalation: Gaining administrative capabilities

Real-World Attack Scenario

The attacker logs in as a standard user and intercepts the HTTP traffic. They observe that object identifiers (like user IDs or document IDs) are passed sequentially. By incrementing or modifying the ID in subsequent requests, they access resources belonging to other users or administrators because the server fails to verify authorization context.

Code Examples

Vulnerable Implementation

// VULNERABLE: Object-level access check missing
function getProfile(userId) {
    return db.find(userId);
}

Secure Alternative

// SECURE: Verifies caller owns the object
function getProfile(userId, activeSession) {
    if (activeSession.id !== userId && !activeSession.isAdmin) throw "Unauthorized";
    return db.find(userId);
}

Detection with Precogs AI

Precogs AI identifies improper authorization patterns through automated binary and source code analysis, detecting CWE-285 weaknesses before they reach production. Our analysis engine examines compiled artifacts without requiring source code access, identifying CWE-285 patterns in vendor software, containers, firmware, and third-party libraries.

Remediation

Implement proper access control controls following secure coding guidelines. Use automated scanning tools like Precogs AI to continuously monitor for CWE-285 vulnerabilities. Apply the principle of least privilege and validate all inputs from untrusted sources.
