|---|
| 설명 | The `getPage()` method in `BaseServiceImpl.java` constructs pagination queries using user-supplied `orderField` and `order` parameters without any input validation or whitelist enforcement. The application directly passes the attacker-controlled `orderField` value into MyBatis-Plus's `OrderItem.asc()` / `OrderItem.desc()` methods, which perform raw string concatenation into the SQL `ORDER BY` clause.
Because the sorting column name in an `ORDER BY` statement cannot be parameterized with prepared statements (`?` placeholders), MyBatis-Plus inserts the field name directly into the generated SQL query. Consequently, an attacker can inject arbitrary SQL expressions through the `orderField` parameter, leading to a time-based blind SQL injection or error-based SQL injection vulnerability. |
