– Examples: Using weak encryption algorithms, failing to secure API keys.

– Mitigation: Employ industry-standard cryptographic practices, regularly review cryptographic implementations, and ensure secure key storage.

3. Injection

– Description: Injection vulnerabilities occur when an application sends untrusted data to an interpreter, allowing attackers to execute arbitrary commands or access sensitive data.

– Examples: SQL injection, XML injection, command injection.

– Mitigation: Use parameterized queries, employ input validation, and practice output encoding to prevent injection attacks.

4. Insecure Design

– Description: This vulnerability highlights the lack of security controls in the design phase of application development. It encompasses insufficient threat modeling and inadequate security requirements.

– Examples: Failing to consider attack vectors during application architecture design.

– Mitigation: Integrate security into the software development lifecycle (SDLC), conduct regular threat modeling sessions, and ensure comprehensive security requirements are established.

5. Security Misconfiguration

– Description: Security misconfigurations arise from improper configuration settings, leaving applications exposed to various threats.

– Examples: Default credentials, unnecessary features enabled, overly permissive permissions.

– Mitigation: Establish a strong configuration management process, regularly audit configurations, and adhere to security benchmarks.

6. Vulnerable and Outdated Components

– Description: This refers to the use of libraries, frameworks, and other software components that are outdated or have known vulnerabilities.

– Examples: Using an outdated version of a web framework with known exploits.

– Mitigation: Regularly update components, use dependency management tools, and monitor for vulnerability disclosures.

7. Identification and Authentication Failures

– Description: This category includes flaws related to user authentication and session management, potentially allowing unauthorized access.

– Examples: Weak password policies, session fixation attacks.

– Mitigation: Implement strong authentication mechanisms, including multi-factor authentication (MFA), and enforce session management best practices.

8. Software and Data Integrity Failures

– Description: This vulnerability arises when software updates or critical data are not validated, allowing attackers to inject untrusted data.

– Examples: Insecure updates, reliance on untrusted sources for software delivery.

– Mitigation: Use digital signatures for software updates, validate data integrity, and employ secure coding practices.

9. Security Logging and Monitoring Failures

– Description: Insufficient logging and monitoring can prevent organizations from detecting and responding to security threats in a timely manner.

– Examples: Lack of logs for user actions, failure to monitor for suspicious activities.

– Mitigation: Implement comprehensive logging practices, establish alerting mechanisms for anomalies, and regularly review logs for suspicious activity.

10. Server-Side Request Forgery (SSRF)

– Description: SSRF occurs when an attacker can make requests from the server on behalf of the application, potentially accessing internal services.

– Examples: Exploiting a web application to access internal APIs or services.

– Mitigation: Validate and sanitize URLs, restrict outgoing requests, and implement network-level controls.
