Security Findings & Remediation

Identified Vulnerabilities

1. Dependency Vulnerabilities (Mongoose 6.12.0)

Severity: Medium

Tool: Snyk, npm audit, Trivy

Finding: Mongoose 6.12.0 and its dependencies have known CVEs

Affected Packages:

mongoose@6.12.0
bson@4.x (transitive dependency)
mongodb@4.x (transitive dependency)

Impact: Potential for NoSQL injection, denial of service

Remediation:

# Update to latest stable version
npm install mongoose@latest

# Or specific version
npm install mongoose@8.0.0

Status: ⚠️ Known issue (kept for demonstration purposes)

2. Missing Input Validation

Severity: High

Tool: Semgrep, OWASP ZAP

Finding: /planet endpoint lacks input sanitization

Vulnerable Code:

app.post('/planet', function(req, res) {
    planetModel.findOne({
        id: req.body.id  // No validation!
    }, ...)
})

Impact: Potential NoSQL injection

Remediation:

const { body, validationResult } = require('express-validator');

app.post('/planet', 
  body('id').isInt({ min: 1, max: 8 }),
  function(req, res) {
    const errors = validationResult(req);
    if (!errors.isEmpty()) {
      return res.status(400).json({ errors: errors.array() });
    }
    // Safe to proceed
})

Status: ⚠️ Intentional (demonstrates SAST/DAST detection)

3. Unrestricted CORS

Severity: Medium

Tool: Semgrep, OWASP ZAP

Finding: CORS enabled for all origins

Vulnerable Code:

app.use(cors())  // Allows all origins

Impact: Potential for CSRF attacks, data theft

Remediation:

app.use(cors({
  origin: 'https://solar-system-ssd.azurewebsites.net',
  credentials: true
}))

Status: ⚠️ Intentional (simplified for demo)

4. No Authentication/Authorization

Severity: Critical

Tool: Manual review, OWASP ZAP

Finding: All endpoints publicly accessible

Impact: Unrestricted data access, potential abuse

Remediation:

const jwt = require('jsonwebtoken');

function authenticate(req, res, next) {
  const token = req.headers.authorization?.split(' ')[1];
  if (!token) return res.status(401).send('Unauthorized');
  
  jwt.verify(token, process.env.JWT_SECRET, (err, user) => {
    if (err) return res.status(403).send('Forbidden');
    req.user = user;
    next();
  });
}

app.post('/planet', authenticate, function(req, res) { ... })

Status: ⚠️ Out of scope (demo application)

5. No Rate Limiting

Severity: High

Tool: OWASP ZAP, manual review

Finding: No rate limiting on API endpoints

Impact: Potential for DoS attacks, resource exhaustion

Remediation:

const rateLimit = require('express-rate-limit');

const limiter = rateLimit({
  windowMs: 15 * 60 * 1000, // 15 minutes
  max: 100 // 100 requests per window
});

app.use('/planet', limiter);

Status: ⚠️ Intentional (simplified demo)

6. Container Base Image Vulnerabilities

Severity: Low to Medium

Tool: Trivy

Finding: Alpine 3.17 base image has known CVEs

Affected Packages:

openssl@3.0.x
libcrypto@3.0.x
libssl@3.0.x

Impact: Potential cryptographic vulnerabilities

Remediation:

# Update base image
FROM node:18-alpine3.19  # Latest Alpine

# Or use distroless for smaller attack surface
FROM gcr.io/distroless/nodejs18-debian11

Status: ✅ Acceptable (base image updated regularly)
