SQL injection (SQLi) là gì?

SQL injection là một lỗ hổng bảo mật web cho phép kẻ tấn công can thiệp vào các truy vấn mà ứng dụng thực hiện đối với cơ sở dữ liệu của nó. Nó thường cho phép kẻ tấn công xem dữ liệu mà chúng thường không thể lấy. Bao gồm dữ liệu thuộc về người dùng hoặc bất kỳ dữ liệu nào khác mà bản thân ứng dụng có thể truy cập. Trong nhiều trường hợp, kẻ tấn công có thể sửa đổi hoặc xóa dữ liệu này, gây ra các thay đổi liên tục đối với nội dung hoặc hành vi của ứng dụng.

Trong một số tình huống, kẻ tấn công có thể leo thang một cuộc tấn công SQL injection để xâm phạm máy chủ hoặc cơ sở hạ tầng back-end hoặc thực hiện một cuộc tấn công từ chối dịch vụ.

Các loại SQL injection:

• In-band SQLi (SQLi cổ điển): In-band SQLi là phương thức tấn công SQL Injection phổ biến và dễ khai thác nhất. In-band SQL Injection xảy ra khi kẻ tấn công có thể sử dụng cùng một kênh liên lạc để khởi động cuộc tấn công và thu thập kết quả. Hai loại SQL Injection phổ biến nhất là SQLi dựa trên lỗi và SQLi dựa trên Union.
• SQLi dựa trên lỗi: SQLi dựa trên lỗi là một kỹ thuật in-band SQL dựa vào các thông báo lỗi do máy chủ cơ sở dữ liệu đưa ra để lấy thông tin về cấu trúc của cơ sở dữ liệu. Trong một số trường hợp, chỉ riêng việc chèn SQL dựa trên lỗi là đủ để kẻ tấn công liệt kê toàn bộ cơ sở dữ liệu.
• SQLi dựa trên Union: SQLi dựa trên Union là một kỹ thuật tiêm SQL in-band sử dụng toán tử SQL UNION để kết hợp các kết quả của hai hoặc nhiều câu lệnh SELECT thành một kết quả duy nhất, sau đó được trả về như một phần của phản hồi HTTP.
• SQLi Suy luận(Blind SQLi): SQLi Suy luận, không giống như SQL in-band, có thể mất nhiều thời gian hơn để kẻ tấn công khai thác, tuy nhiên, nó cũng nguy hiểm như bất kỳ dạng SQL Injection nào khác. Trong một cuộc tấn công SQLi Suy luận, không có dữ liệu nào thực sự được chuyển qua ứng dụng web và kẻ tấn công sẽ không thể nhìn thấy kết quả của một cuộc tấn công in-band (đó là lý do tại sao các cuộc tấn công như vậy thường được gọi là “tấn công mù SQL Injection”) . Thay vào đó, kẻ tấn công có thể xây dựng lại cấu trúc cơ sở dữ liệu bằng cách gửi payloads, quan sát phản hồi của ứng dụng web và kết quả của máy chủ cơ sở dữ liệu. Hai kiểu SQL Injection suy luận là SQLi dựa trên Blind-boolean và SQLi dựa trên thời gian mù.
• SQLi mù dựa trên Boolean (dựa trên nội dung): SQL Injection dựa trên Boolean là một kỹ thuật SQL Injection suy luận dựa trên việc gửi một truy vấn SQL đến cơ sở dữ liệu, buộc ứng dụng trả về một kết quả khác tùy thuộc vào việc truy vấn trả về TRUE hay FALSE. Tùy thuộc vào kết quả, nội dung bên trong phản hồi HTTP sẽ thay đổi hoặc giữ nguyên. Điều này cho phép kẻ tấn công suy luận xem payload được sử dụng trả về true hay false, mặc dù không có dữ liệu nào từ cơ sở dữ liệu được trả về.
• SQLi mù dựa trên thời gian: SQL Injection dựa trên thời gian là một kỹ thuật SQL Injection suy luận dựa trên việc gửi một truy vấn SQL đến cơ sở dữ liệu, buộc cơ sở dữ liệu phải đợi một khoảng thời gian cụ thể (tính bằng giây) trước khi phản hồi. Thời gian phản hồi sẽ cho kẻ tấn công biết kết quả của truy vấn là TRUE hay FALSE. Tùy thuộc vào kết quả, phản hồi HTTP sẽ được trả lại trễ hoặc trả về ngay lập tức. Điều này cho phép kẻ tấn công suy luận xem payload được sử dụng trả về true hay false, mặc dù không có dữ liệu nào từ cơ sở dữ liệu được trả về.
• SQLi ngoài băng tần: SQL Injection ngoài băng tần không phổ biến lắm, chủ yếu là do nó phụ thuộc vào các tính năng được bật trên máy chủ cơ sở dữ liệu đang được ứng dụng web sử dụng. SQL Injection ngoài băng tần xảy ra khi kẻ tấn công không thể sử dụng cùng một kênh để khởi động cuộc tấn công và thu thập kết quả. Các kỹ thuật ngoài băng tần, cung cấp cho kẻ tấn công một giải pháp thay thế cho các kỹ thuật dựa trên thời gian suy diễn, đặc biệt nếu phản hồi của máy chủ không ổn định lắm (làm cho một cuộc tấn công dựa trên thời gian suy diễn không đáng tin cậy).
• Sql Injection dựa trên âm thanh: Đây là một phương pháp tấn công sql injection có thể được áp dụng trong các ứng dụng cung cấp quyền truy cập vào cơ sở dữ liệu bằng lệnh thoại. Kẻ tấn công có thể lấy thông tin từ cơ sở dữ liệu bằng cách gửi các truy vấn sql kèm theo âm thanh.

Câu hỏi thường gặp

SQL injection là gì và tại sao nó nguy hiểm?

SQL injection là một lỗ hổng bảo mật cho phép kẻ tấn công chèn mã SQL độc hại vào các truy vấn cơ sở dữ liệu của ứng dụng web. Điều này có thể dẫn đến việc truy cập trái phép, sửa đổi hoặc xóa dữ liệu nhạy cảm, thậm chí kiểm soát toàn bộ hệ thống.

Tôi có thể làm gì để bảo vệ ứng dụng web của mình khỏi SQL injection?

Hãy sử dụng các kỹ thuật lập trình an toàn như chuẩn bị câu lệnh (prepared statements) hoặc sử dụng thư viện ORM, thường xuyên cập nhật phần mềm và áp dụng các biện pháp phòng ngừa khác như đầu vào được xác thực và mã hóa đầu ra.

Có những công cụ nào giúp phát hiện và ngăn chặn SQL injection?

Có nhiều công cụ như SQLMap, jSQL Injection, BBQSQL và các công cụ quét lỗ hổng khác có thể giúp phát hiện SQL injection. Ngoài ra, việc sử dụng tường lửa ứng dụng web (WAF) cũng rất hiệu quả trong việc ngăn chặn các cuộc tấn công này.
