ApiPosturePro 1.0.9

ApiPosture Pro

Professional security extension for ASP.NET Core API security scanning

Extends the open-source ApiPosture CLI with advanced security rules, secrets detection, diff mode, historical tracking, and risk scoring.

🔒 100% Local Analysis - Your code never leaves your machine. All scanning is performed locally on your computer or CI/CD runner.

Features

🛡️ OWASP Top 10 Security Rules

Advanced detection combining endpoint metadata analysis with deep source code inspection of method bodies:

• AP101 - Broken Access Control (Critical) — missing [Authorize], database writes without auth, IDOR without ownership checks
• AP102 - Cryptographic Failures (High) — weak hashing (MD5/SHA1), hardcoded crypto keys, sensitive data logging
• AP103 - Injection Vulnerabilities (Critical) — ExecuteSqlRaw with interpolation/concatenation, BinaryFormatter, insecure TypeNameHandling, Process.Start
• AP104 - Insecure Design (High) — missing CSRF tokens, missing ModelState.IsValid, missing rate limiting
• AP105 - Security Misconfiguration (Medium) — XXE via DtdProcessing.Parse, XmlTextReader without DTD prohibition, permissive CORS
• AP106 - Vulnerable Components (Medium) — legacy API patterns, deprecated frameworks
• AP107 - Authentication Failures (High) — missing audit logging on DELETE, plaintext password comparison
• AP108 - SSRF Vulnerabilities (High) — HttpClient/WebClient with user input, URI construction from variables

📂 File-Level Scanning

Scans entire source files beyond just endpoint methods:

• Startup.cs / Program.cs — UseDeveloperExceptionPage() without environment guard, missing UseHttpsRedirection(), missing UseHsts()
• Razor Views (*.cshtml) — @Html.Raw() XSS vulnerabilities, innerHTML assignments
• C# Source Files (*.cs) — Reversible encryption in password context, hardcoded encryption keys, BinaryFormatter, insecure TypeNameHandling

🔑 Secrets Detection

• AP201 - Detects 30+ secret patterns in both source files and method bodies (Critical)
• AWS, Azure, GCP keys
• GitHub, Slack, Stripe tokens
• Database connection strings
• Private keys and certificates
• JWT secrets and API keys

📊 Diff Mode

Compare scans over time to track security improvements or regressions:

apiposture-pro diff baseline.json current.json

📈 Historical Tracking

Automatic scan history with SQLite storage:

apiposture-pro history list
apiposture-pro history trend -p /path/to/project

🎯 Risk Scoring

Automated risk assessment based on:

• Severity (40%)
• Exposure (25%)
• Sensitivity (25%)
• Finding density (10%)

API Posture Scan Results
========================

Findings:
  [AP101] Critical: Endpoint '/api/entries' performs database writes without authorization
  [AP102] High: Endpoint '/api/users/hash' uses weak hashing algorithm (MD5/SHA1)
  [AP103] Critical: Endpoint '/api/comments' uses ExecuteSqlRaw with string interpolation
  [AP105] Critical: Endpoint '/api/rss' enables DTD processing which allows XXE attacks
  [AP105] High: UseDeveloperExceptionPage() is used without an environment check
  [AP103] High: @Html.Raw() used in Show.cshtml at line 12
  [AP201] Critical: AWS Access Key detected in appsettings.json

Summary:
  Total Findings: 7
  Critical: 4 | High: 3 | Medium: 0 | Low: 0

Scanned 42 endpoints + 18 files in 2.3s

Automatic History Tracking

Every scan is automatically saved to your local history database (~/.apiposture/history.db):

$ apiposture-pro scan /path/to/api
[scan output...]
Scan saved to history: a1b2c3d4e5f6

# View your scan history
$ apiposture-pro history list

# Show trend for your project
$ apiposture-pro history trend -p /path/to/api

Compare Scans (Diff Mode)

Track security improvements over time:

# Save baseline
apiposture-pro scan /path/to/api --output json --output-file baseline.json

# Make security improvements...

# Scan again
apiposture-pro scan /path/to/api --output json --output-file current.json

# Compare results
apiposture-pro diff baseline.json current.json

View History

Pro automatically records scan history:

# List recent scans
apiposture-pro history list

# View trends over time
apiposture-pro history trend -p /path/to/api

# Show specific scan
apiposture-pro history show <scan-id>

Security Rules Reference

AP101: Broken Access Control

Severity: Critical

Detects missing authorization on sensitive operations, IDOR vulnerabilities, mass assignment risks, and privilege escalation endpoints. Source code analysis detects database writes (.Add(), .SaveChangesAsync()) on public endpoints and data access by ID without ownership verification.

Recommendation: Use [Authorize] attributes with appropriate roles/policies. Verify resource ownership before returning data.

AP102: Cryptographic Failures

Severity: High

Detects sensitive data in URLs, weak hashing algorithms (MD5.Create(), SHA1.Create()), hardcoded cryptographic keys (Convert.FromBase64String("...")), reversible encryption used for passwords, and sensitive data logged via .ToString() or string interpolation.

Recommendation: Use SHA-256+ for hashing, bcrypt/Argon2 for passwords. Store keys in secure configuration. Never log sensitive objects.

AP103: Injection Vulnerability

Severity: Critical

Detects SQL injection via ExecuteSqlRaw/FromSqlRaw with string interpolation or concatenation, insecure deserialization (TypeNameHandling.Auto/All), BinaryFormatter usage, Process.Start command injection, and XSS via @Html.Raw() in Razor views.

Recommendation: Use ExecuteSqlInterpolated or parameterized queries. Use System.Text.Json instead of BinaryFormatter. Avoid @Html.Raw() with user data.

AP104: Insecure Design

Severity: High

Detects missing rate limiting on auth endpoints, [HttpPost] actions without [ValidateAntiForgeryToken], POST/PUT methods without ModelState.IsValid checks, and bulk operations without limits.

Recommendation: Add CSRF protection, validate input models, implement rate limiting and CAPTCHA.

AP105: Security Misconfiguration

Severity: Medium

Detects exposed debug endpoints, XXE vulnerabilities (DtdProcessing.Parse, XmlTextReader without DTD prohibition), permissive CORS (AllowAnyOrigin()), UseDeveloperExceptionPage() without environment guard, and missing UseHttpsRedirection()/UseHsts().

Recommendation: Set DtdProcessing.Prohibit. Guard dev middleware with IsDevelopment(). Enforce HTTPS and HSTS.

AP106: Vulnerable Components

Severity: Medium

Detects legacy API patterns, deprecated frameworks, and outdated web service endpoints.

Recommendation: Keep components updated. Migrate legacy services to modern patterns.

AP107: Authentication Failures

Severity: High

Detects weak auth patterns, basic auth usage, missing audit logging on DELETE endpoints, plaintext password comparison (== password), and improper session/token management.

Recommendation: Use bcrypt/Argon2 for password verification. Log all destructive operations. Use MFA and secure session handling.

AP108: SSRF Vulnerability

Severity: High

Detects endpoints accepting URL parameters, HttpClient.GetAsync()/WebClient.DownloadString() with user input, new Uri(variable) construction, webhooks, and proxy functionality.

Recommendation: Validate URL inputs against allowlists. Block internal IP ranges. Use typed HTTP clients.

AP201: Secrets in Code

Severity: Critical

Detects 30+ hardcoded secret patterns in both source files and endpoint method bodies, including cloud keys, service tokens, database credentials, and private keys.

Recommendation: Never hardcode secrets. Use environment variables or secure vaults.
