database-security SKILL.md skillA

database-security from novaestellar/novahaku is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add novaestellar/novahaku/database-security@git:20260910.546fe86

Pins git:20260910.546fe86 in mdr.lock. Pin the fingerprint instead.

Use for authorized database security assessment covering PostgreSQL/MySQL/MSSQL/Mongo/Redis exposure, authz, UDF/command paths, and misconfiguration review.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Database Security Assessment

## ACTION REQUIRED（读完后立刻执行）

1. `NOW`: 读取 precedent-pentest；**生产库禁止破坏性语句** unless 明确允许
2. `NOW`: scope 写清实例、账号权限、是否允许写/删
3. `NEXT`: 客户端工具路径
4. `ACT`: 暴露面 → 认证 → 授权 → 配置 → 利用链验证（安全）

## 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？

How to install

The exact contents, by fingerprint

mdr add novaestellar/novahaku/database-security@sha256:a0bfae413b9762ad

The line at the top of this page pins the label git:20260910.546fe86, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
