Common pattern recognition methods for permission black hole vulnerabilities include:
Access Control Analysis: Identify overly permissive roles or policies granting excessive access, e.g., wildcard permissions (*) in IAM configurations.
Privilege Escalation Detection: Monitor for misconfigured APIs or functions allowing users to elevate privileges, like AWS Lambda or Kubernetes RBAC exploits.
Static Code Analysis: Scan code for hardcoded credentials or insecure permission checks bypassing authorization.
Dynamic Testing: Perform penetration testing to uncover unintended access paths, such as exploiting weak session tokens.
Log and Audit Review: Analyze logs for anomalous access patterns, like unauthorized resource access attempts.
Dependency Mapping: Trace permission flows across microservices or APIs to spot over-privileged endpoints.
Automated Scanners: Use tools like OWASP ZAP or Burp Suite to detect misconfigurations.
