> **⚠️ AUTHORIZED USE ONLY**
> This skill is for educational purposes or authorized security assessments only.
> You must have explicit, written permission from the system owner before using this tool.
> Misuse of this tool is illegal and strictly prohibited.

> **Mandatory confirmation gate**
> Before running any command that probes, exploits, changes, persists on, extracts data from, or attempts credential access against a target:
> 1. Ask the user to state the exact target URL, IP, account, or resource.
> 2. Ask the user to confirm written authorization and the permitted scope.
> 3. Show the exact command(s) and explain their expected effect.
> 4. Wait for explicit confirmation in the current conversation.
>
> Without that confirmation, remain read-only and provide defensive guidance only. Prefer a sandbox, disposable VM, or controlled lab.

# Database Security Assessment
## When to Use

- Assessing database hardening and exposure within an approved scope.
- Checking authz boundaries and risky server-side execution features.


## 适用场景

- 数据库未授权/弱口令/错误绑定 0.0.0.0
- 权限过大、危险功能（xp_cmdshell、COPY PROGRAM、UDF）
- 横向：从应用账号到 DBA
- NoSQL 注入与 Redis 写文件等（授权环境）

## 工作流

```text
□ 网络暴露与 TLS
□ 账号角色与 grantee
□ 敏感表访问控制
□ 危险配置：file_priv、xp_cmdshell、load_file
□ 审计日志是否开启
□ 备份与快照权限
```

## 工具链

| 工具 | 用途 |
|------|------|
| 官方 CLI | 连接与枚举 |
| sqlmap | 注入验证（授权） |
| nuclei | 已知暴露模板 |
| 云 RDS 控制台审计 | 配置 |

## 参考

- `references/db-misconfig-checklist.md`
- `../pentest-tools/` `../cloud-k8s/`

## 路由上下文

**上游**: MASTER R35  
**下游**: 获 OS 命令 → attack-chain；云托管 → cloud-k8s

## 任务完成自检

- [ ] 是否避免未授权写删？
- [ ] 是否区分配置问题与可利用链？
- [ ] Checklist？

## Limitations

- Never run against production data stores without explicit written approval.
- Active exploitation paths (UDF/command exec) are destructive-capable; simulate first.
