**Stack:** Kubernetes

- Prevalence: Alta Frequentemente explorada
- Impact: Crítico 6 regras de severidade crítica
- Prevention: Documentada 11 exemplos de correção

**OWASP:** Identification and Authentication Failures (A07:2021-Identification and Authentication Failures) - #7

## Description

Hard-coded credentials typically create a significant hole that allows an attacker to bypass the authentication that has been configured by the product administrator. This hole might be difficult for the system administrator to detect.

## Prevention

Estratégias de prevenção para Hardcoded Credentials baseadas em 1 regras de detecção do Shoulder.

### Kubernetes

Use Kubernetes Secrets with secretKeyRef instead of hardcoding credentials in manifests

## Warning Signs

- [CRITICAL] Secrets, passwords, or API keys are hardcoded in the Kubernetes manifest.
- [CRITICAL] hardcoded secrets, passwords, or API keys in Kubernetes manifests

## Consequences

- Obter privilégios
- Burlar mecanismo de proteção

## Mitigations

- Armazene credenciais fora do código-fonte
- Use variáveis de ambiente ou cofres seguros de credenciais
- Implemente procedimentos adequados de gerenciamento de chaves

## Detection

- Total rules: 11
- Critical: 6
- Languages: python, dockerfile, go, javascript, typescript, yaml

## Rules by Language

### Yaml (1 rules)

- **Hardcoded Secrets in Manifest** [CRITICAL]: Detects hardcoded secrets, passwords, or API keys in Kubernetes manifests.
  - Remediation: Use Kubernetes Secrets with valueFrom.

```yaml
env:
  - name: DB_PASSWORD
    valueFrom:
      secretKeyRef:
        name: db-secret
        key: password
```
