# Active Debug Code (CWE-489)

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

**Stack:** Go

- Prevalence: Élevée Fréquemment exploitée
- Impact: Critique 1 règles de sévérité critique
- Prevention: Documentée 6 exemples de correctifs

**OWASP:** Security Misconfiguration (A05:2021-Security Misconfiguration) - #5

## Description

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.

## Prevention

Stratégies de prévention pour Active Debug Code basées sur 3 règles de détection Shoulder.

### Go

Disable Echo debug mode in production to prevent stack trace exposure

Disable Fiber debug output and route printing in production

Set Gin to release mode in production to suppress debug output

## Consequences

- Lecture des données de l'application
- Contourner le mécanisme de protection
- Exécuter du code non autorisé

## Mitigations

- Supprimez le code de débogage avant de déployer le produit en production
- Utilisez des configurations de build qui excluent automatiquement le code de débogage des builds de production
- Auditez le code à la recherche de points de terminaison de débogage et de portes dérobées avant la mise en production

## Detection

- Total rules: 6
- Critical: 1
- Languages: python, go, javascript, typescript

## Rules by Language

### Go (3 rules)

- **Echo Debug Mode in Production** [MEDIUM]: Echo debug mode exposes stack traces and verbose errors in production.
  - Remediation: Disable debug mode in production.

```go
e := echo.New()
e.Debug = false
```

- **Fiber Debug Mode in Production** [MEDIUM]: Fiber debug configuration exposes route structure and stack traces.
  - Remediation: Use production configuration to disable debug output.

```go
app := fiber.New(fiber.Config{
    DisableStartupMessage: true,
    EnablePrintRoutes:     false,
})
```

- **Gin Debug Mode in Production** [MEDIUM]: Gin debug mode exposes routing info and verbose errors in production.
  - Remediation: Set release mode before creating the router.

```go
gin.SetMode(gin.ReleaseMode)
r := gin.Default()
```
