# 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: Wysoka Często wykorzystywana
- Impact: Krytyczny 1 reguł o krytycznym poziomie
- Prevention: Udokumentowane 6 przykładów poprawek

**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

Strategie zapobiegania dla Active Debug Code oparte na 3 regułach detekcji 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

- Odczyt danych aplikacji
- Obejście mechanizmu ochrony
- Wykonanie nieautoryzowanego kodu

## Mitigations

- Usuń kod debugujący przed wdrożeniem produktu na produkcję
- Stosuj konfiguracje build, które automatycznie wykluczają kod debugowy z buildów produkcyjnych
- Przed wydaniem audytuj kod pod kątem endpointów debugowych i tylnych furtek

## 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()
```
