Active Debug Code (CWE-489) - Security Vulnerability

Active Debug Code

The product is deployed to unauthorized actors with debugging code still enabled or active, which can create unintended entry points or information leaks.

Debug code is often written to allow easier testing and debugging. This code is not intended to be shipped to production but is sometimes inadvertently left in the product. Debug code often exposes information about the product's internal structure or creates additional attack surface.

Stratégies de prévention pour Active Debug Code basées sur 6 règles de détection Shoulder.

🐍 Python Tout voir Python détails →

Django Debug Mode in Production CRITICAL

Load DEBUG from environment variables, defaulting to False in production

+4 -2 python

  # settings.py
- DEBUG = True
- ALLOWED_HOSTS = ['*']
+ import os
+ 
+ DEBUG = os.getenv('DJANGO_DEBUG', 'False').lower() == 'true'
+ ALLOWED_HOSTS = os.getenv('ALLOWED_HOSTS', '').split(',')

Flask Debug Mode in Production HIGH

Load Flask debug mode from environment variables, defaulting to False

+8 -6 python

- from flask import Flask
- 
- app = Flask(__name__)
- 
- if __name__ == '__main__':
-     app.run(debug=True)
+ import os
+ from flask import Flask
+ 
+ app = Flask(__name__)
+ 
+ if __name__ == '__main__':
+     debug = os.getenv('FLASK_DEBUG', 'False').lower() == 'true'
+     app.run(debug=debug)

Echo Debug Mode in Production MEDIUM

Disable Echo debug mode in production to prevent stack trace exposure

+8 -5 go

  package main
  
- import "github.com/labstack/echo/v4"
- 
- func main() {
-     e := echo.New()
-     e.Debug = true
+ import (
+     "os"
+     "github.com/labstack/echo/v4"
+ )
+ 
+ func main() {
+     e := echo.New()
+     e.Debug = os.Getenv("ECHO_DEBUG") == "true"
      e.GET("/api/users", getUsers)
      e.Start(":8080")
  }

Fiber Debug Mode in Production MEDIUM

Disable Fiber debug output and route printing in production

+3 -2 go

  package main
  
  import "github.com/gofiber/fiber/v2"
  
  func main() {
      app := fiber.New(fiber.Config{
-         EnablePrintRoutes: true,
-         EnableStackTrace:  true,
+         DisableStartupMessage: true,
+         EnablePrintRoutes:     false,
+         Prefork:               true,
      })
      app.Get("/api/users", getUsers)
      app.Listen(":8080")
  }

Gin Debug Mode in Production MEDIUM

Set Gin to release mode in production to suppress debug output

+9 -4 go

  package main
  
- import "github.com/gin-gonic/gin"
- 
- func main() {
-     gin.SetMode(gin.DebugMode)
+ import (
+     "os"
+     "github.com/gin-gonic/gin"
+ )
+ 
+ func main() {
+     if os.Getenv("GIN_MODE") == "" {
+         gin.SetMode(gin.ReleaseMode)
+     }
      r := gin.Default()
      r.GET("/api/users", getUsers)
      r.Run(":8080")
  }

🟨 JavaScript Tout voir JavaScript détails →

Debug Mode Enabled in Production MEDIUM

Use environment variables for debug configuration instead of hardcoded flags

+6 -2 javascript

- const DEBUG = true;
- app.use(morgan('dev'));
+ const DEBUG = process.env.DEBUG === 'true';
+ const isProduction = process.env.NODE_ENV === 'production';
+ 
+ if (!isProduction) {
+   app.use(morgan('dev'));
+ }

Règles de Détection (6)

🐹 Go 3 rules

Echo Debug Mode in Production MEDIUM

Echo debug mode exposes stack traces and verbose errors in production.

Fiber Debug Mode in Production MEDIUM

Fiber debug configuration exposes route structure and stack traces.

Gin Debug Mode in Production MEDIUM

Gin debug mode exposes routing info and verbose errors in production.

🐍 Python 2 rules

Django Debug Mode in Production CRITICAL

Detects Django applications with DEBUG = True in settings. Debug mode exposes sensitive information including settings, environment variables, SQL queries, and stack traces. This must NEVER be enabled in production.

Flask Debug Mode in Production HIGH

Detects Flask applications running with debug mode enabled. Debug mode exposes sensitive information, allows code execution through the interactive debugger, and should NEVER be enabled in production.

🟨 Javascript 1 rules

Debug Mode Enabled in Production MEDIUM

Detects hardcoded debug flags that expose sensitive information or enable debugging features in production.

🔷 Typescript 1 rules

Debug Mode Enabled in Production MEDIUM

Detects hardcoded debug flags that expose sensitive information or enable debugging features in production.
