Web Security Review (OWASP Top 10)

Review web applications against all 10 OWASP Top 10 risks by following the full procedure in plays/owasp-top10-web-review.md.

Steps

1. Application Mapping — Identify framework/language, deployment model (monolith/microservices), trust boundaries (internet/internal/local), data sensitivity (PII, financial, health), and authentication mechanisms.

2. Assess Each OWASP Top 10 Risk:

   • A01 Broken Access Control — Missing authz checks, IDOR, privilege escalation, path traversal, CORS misconfigurations
   • A02 Cryptographic Failures — Weak algorithms, missing TLS, hardcoded keys, improper key management, cleartext storage
   • A03 Injection — SQLi, NoSQLi, OS command injection, LDAP injection, XSS, SSTI, XPath injection
   • A04 Insecure Design — Missing security requirements, business logic flaws, insecure workflows, threat modeling gaps
   • A05 Security Misconfiguration — Default configs, verbose errors, missing headers, unnecessary features, outdated components
   • A06 Vulnerable Components — Unpatched libraries, unsupported dependencies, lack of inventory, missing SBOM
   • A07 Identification & Auth Failures — Weak passwords, session issues, MFA gaps, credential stuffing, brute force
   • A08 Software & Data Integrity Failures — Insecure deserialization, unsigned updates, CI/CD attacks, dependency confusion
   • A09 Security Logging & Monitoring Failures — Missing audit logs, insufficient monitoring, no incident response capability
   • A10 Server-Side Request Forgery (SSRF) — Unvalidated URL parameters, internal service access, cloud metadata endpoints

3. Framework-Specific Analysis — Apply checks for detected framework (React, Angular, Vue, Express, Django, Flask, Rails, Spring, ASP.NET, Laravel).

4. Configuration Review — Examine web server configs (nginx, Apache), application configs, and deployment manifests for security settings.

Output

Application overview, risk matrix for all 10 categories with severity/status, detailed findings using templates/finding.md, positive controls observed, and prioritized remediation roadmap.
