# 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: Hoch Häufig ausgenutzt
- Impact: Kritisch 1 Regeln mit kritischem Schweregrad
- Prevention: Dokumentiert 6 Fix-Beispiele

**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

Präventionsstrategien für Active Debug Code basierend auf 3 Shoulder-Erkennungsregeln.

### 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

- Anwendungsdaten lesen
- Schutzmechanismus umgehen
- Nicht autorisierten Code ausführen

## Mitigations

- Debug-Code vor dem Deployment in die Produktion entfernen
- Build-Konfigurationen verwenden, die Debug-Code automatisch aus Produktions-Builds ausschließen
- Code vor dem Release auf Debug-Endpunkte und Hintertüren prüfen

## 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()
```
