Top 30 Vulnerabilities IntelliScan Detects & Mitigates

IntelliScan treats security as a top priority by identifying these critical vulnerabilities, helping you stay compliant and reduce breach risks.

• 1. No Input Sanitization/Validation (95% frequency)

  The most pervasive vulnerability caused by missing or incomplete user input validation, leading to injection attacks like SQLi, XSS, and command injection.

• 2. SQL Injection (85% frequency)

  Injection of malicious SQL queries due to unsafe query construction, often via string concatenation without parameterization.

• 3. Authentication Bypass (75% frequency)

  Logic flaws that allow attackers to circumvent authentication protections, gaining unauthorized access.

• 4. Hardcoded Secrets and API Keys (70% frequency)

  Embedding API keys, database credentials, and secrets in code repositories, risking leakage.

• 5. Command Injection (58% frequency)

  Executing user-supplied input directly in system commands, enabling arbitrary code execution.

• 6. Insecure Deserialization (Pickle) (55% frequency)

  Use of unsafe deserialization methods without validation, risking remote code execution.

• 7. Buffer Overflow (50% frequency)

  Unchecked memory access vulnerabilities common especially in C/C++ code, allowing system compromise.

• 8. Use After Free (30% frequency)

  Memory corruption error where freed resources are accessed, leading to undefined and exploitable behavior.

• 9. Memory Corruption (33% frequency)

  Lack of bounds checking or unsafe memory handling resulting in exploitable conditions.

• 10. Heap Buffer Overflow (18% frequency)

  Memory management flaws that corrupt heap metadata, enabling arbitrary code execution.

• 11. Cross-Site Scripting (XSS) (80% frequency)

  Improper output encoding that allows injection of malicious client-side scripts.

• 12. Improper Access Controls (70% frequency)

  Missing authorization checks allowing unauthorized resource access.

• 13. Server-Side Request Forgery (SSRF) (65% frequency)

  Manipulation of server requests to internal or protected resources.

• 14. Path Traversal/Directory Traversal (52% frequency)

  Vulnerabilities allowing attackers to access files and directories outside intended paths.

• 15. Insecure Direct Object Reference (IDOR) (45% frequency)

  Exposing object identifiers in URLs or APIs without proper access control checks.

• 16. Missing Authorization Checks (43% frequency)

  Endpoints lacking permission checks before performing sensitive operations.

• 17. Weak Password Storage (40% frequency)

  Using weak or outdated hashing algorithms or storing passwords in plaintext.

• 18. File Upload Vulnerabilities (35% frequency)

  Incorrect file validation allowing upload of malicious files or denial of service.

• 19. Sensitive Data Exposure (10% frequency)

  Improper handling or storing of personally identifiable or confidential data.

• 20. Client-Side Authentication (28% frequency)

  Authentication logic handled wholly on the client, vulnerable to bypasses.

• 21. Format String Vulnerabilities (23% frequency)

  Unvalidated format strings that can lead to memory disclosure or code execution.

• 22. Cross-Site Request Forgery (CSRF) (60% frequency)

  Missing anti-CSRF tokens causing unauthorized commands to be transmitted from a user.

• 23. Information Disclosure via Error Messages (48% frequency)

  Verbose error handling exposing internal paths, configurations, or database details.

• 24. Race Conditions (38% frequency)

  Concurrent operations failing to lock shared resources properly, causing inconsistent state.

• 25. Insecure File Handling (25% frequency)

  Processing files without validation, sandboxing, or security controls.

• 26. Integer Overflow/Underflow (20% frequency)

  Numeric operations exceeding defined limits causing logic errors or exploits.

• 27. Missing CSRF Protection (15% frequency)

  State-changing requests lacking CSRF tokens, allowing attackers to forge requests.

• 28. Unvalidated Redirects (13% frequency)

  Redirect URLs not checked, enabling phishing or open redirect attacks.

• 29. Security Misconfiguration (12% frequency)

  Default configs, exposed dev tools, or weak security headers/errors.

• 30. Broken Session Management (8% frequency)

  Improper session handling exposing session hijacking or fixation risk.
