- Broken Authentication and Session Management (BASM):
- A critical OWASP Top 10 vulnerability that arises from poor handling of user authentication and session controls.
- Common causes include developer negligence and insecure practices that allow attackers to hijack or reuse valid sessions.
- Key causes and developer mistakes:
- Exposing session IDs in the URL.
- Failing to implement proper session timeouts.
- Reusing the same session ID before and after login.
- Storing or transmitting session cookies insecurely, making them vulnerable to theft (e.g., via XSS).
- Common exploitation methods:
- Brute Force Attacks:
- Attackers use automated tools (like Burp Suite Intruder in cluster bomb mode) to guess valid username-password pairs.
- Exploits weak password policies or lack of rate-limiting.
- SQL Injection Login Bypass:
- Attackers inject malicious SQL payloads (e.g., 1=1, ' OR '1'='1) into login fields.
- The server interprets the input as a valid condition, granting unauthorized access without valid credentials.
- Brute Force Attacks:
- Prevention and mitigation strategies:
- Implement Multi-Factor Authentication (MFA): Adds an extra verification layer against stolen or brute-forced credentials.
- Enforce strong password policies: Disallow weak or default credentials; check against known password breach lists.
- Prevent account enumeration: Use identical messages for login, registration, and recovery outcomes.
- Limit failed login attempts: Apply lockouts, rate limits, and alert administrators of repeated failures.
- Use secure session management:
- Generate new random session IDs after login (high entropy).
- Avoid placing session IDs in URLs.
- Invalidate sessions on logout or inactivity.
- Store session data securely on the server side.
- Core takeaway:
Understanding BASM helps identify how insecure session handling and weak authentication mechanisms can compromise entire systems. Applying layered defenses ensures both authentication robustness and session integrity.
