Understanding Vulnerability

Vulnerabilities can exist in code, configuration, or design. They're rated using CVSS (Common Vulnerability Scoring System) from 0-10. Critical vulnerabilities (9.0-10.0) require immediate attention. Vulnerability management involves identification, prioritization, remediation, and verification.

Examples

  • Critical: Remote code execution without authentication
  • High: SQL injection in a login form
  • Medium: Cross-site scripting in a comment field
  • Low: Information disclosure in error messages
