• SQL injection vulnerability detection
• LDAP injection pattern analysis
• XSS (Cross-Site Scripting) vulnerability scanning
• Command injection detection
• Path traversal vulnerability analysis
• Deserialization attack vectors
• XML External Entity (XXE) vulnerabilities

2. Authentication and Authorization:

• Spring Security configuration analysis
• JWT token handling patterns
• OAuth2 implementation analysis
• Session management security
• Password hashing algorithm detection
• Role-based access control (RBAC) patterns
• CSRF protection implementation

3. Data Protection:

• Encryption algorithm usage
• Secure random number generation
• Certificate and key management
• Database connection security
• Data masking and redaction patterns
• PCI DSS compliance patterns
• GDPR data handling analysis

4. Web Application Security:

• HTTP security headers analysis
• HTTPS enforcement patterns
• Content Security Policy (CSP) implementation
• Cross-Origin Resource Sharing (CORS) configuration
• Input sanitization patterns
• Output encoding analysis

5. Enterprise Security Patterns:

• Secure service communication
• API gateway security patterns
• Microservice security boundaries
• Container security practices
• Secrets management patterns
• Audit logging implementation

6. Common Vulnerability Patterns:

• Hardcoded credentials detection
• Weak cryptographic algorithms
• Insecure direct object references
• Security misconfiguration detection
• Insufficient logging and monitoring
• Known vulnerable dependencies

Implementation:

• Create JavaSecurityAnalysis module
• Implement vulnerability scanning algorithms
• Add security pattern recognition
• Create security scoring system

Acceptance Criteria:

• Major security vulnerabilities detected

🔒 Java Security Vulnerability Analysis - Solution Approach

Current State Analysis

The Java analysis infrastructure from issue #70 provides basic security analysis stubs, but comprehensive security vulnerability detection needs to be implemented.

Implementation Strategy (5 Phases)

Phase 1: Core Security Infrastructure

1. Security Analysis Framework

   • SecurityVulnerability detection engine
   • VulnerabilityType categorization system
   • Severity scoring (Critical, High, Medium, Low)
   • Security pattern matching infrastructure

2. AST Security Pattern Recognition

   • Method call security analysis
   • Parameter flow security tracking
   • Annotation-based security detection
   • Configuration security scanning

Phase 2: Input Validation Vulnerabilities

1. Injection Attack Detection

   • SQL injection patterns (string concatenation, PreparedStatement analysis)
   • LDAP injection via string building
   • Command injection through Runtime.exec, ProcessBuilder
   • XSS through unescaped output patterns
   • Path traversal via File operations

2. Deserialization Security

   • Unsafe ObjectInputStream usage
   • Serializable class analysis
   • readObject method security review

Phase 3: Authentication & Authorization

1. Spring Security Integration

   • @PreAuthorize/@PostAuthorize analysis
   • SecurityConfig detection and analysis
   • Authentication provider patterns
   • JWT token handling security

2. Session & Access Control

   • Session management patterns
   • RBAC implementation analysis
   • CSRF protection detection
   • OAuth2 configuration security

Phase 4: Data Protection & Cryptography

1. Encryption Analysis

   • Algorithm strength detection (AES, RSA key sizes)
   • Secure random number generation
   • Certificate validation patterns
   • Key management security

2. Data Handling Security

   • Database connection security patterns
   • Data masking/redaction detection
   • Compliance pattern recognition (PCI DSS, GDPR)

Phase 5: Enterprise & Web Security

1. Web Security Patterns

   • HTTP security headers analysis
   • CORS configuration review
   • CSP implementation detection
   • Input sanitization patterns

2. Enterprise Security

   • Microservice security boundaries
   • API gateway security patterns
   • Secrets management analysis
   • Audit logging implementation

Technical Implementation Details

Security Detection Algorithms:

• AST pattern matching for vulnerability signatures
• Data flow analysis for injection detection
• Configuration parsing for security settings
• Annotation analysis for security frameworks

Vulnerability Scoring System:

• CVSS-based severity scoring
• Context-aware risk assessment
• Framework-specific security recommendations
• Compliance mapping (OWASP Top 10, CWE)

Integration Points:

• Spring Security framework detection
• Jakarta EE security analysis
• Apache Shiro pattern recognition
• Custom security framework support

This approach will create production-ready Java security analysis covering the full spectrum of enterprise security concerns.
