Detection Guidance

This SQL injection vulnerability can be detected by testing the endpoints that accept the `orderBy` parameter, especially the public endpoint `/mall/product/0/20` which is accessible without authentication.

A common approach is to use automated SQL injection detection tools such as sqlmap to test for injection points by injecting payloads that cause time delays or error messages.

• Use sqlmap with a time-based blind SQL injection payload targeting the `orderBy` parameter to detect if the database response is delayed, indicating vulnerability.
• Example command: sqlmap -u "http://target/mall/product/0/20?orderBy=price" --time-sec=10 --technique=T --dbms=mysql

Mitigation Strategies

Immediate mitigation involves preventing unsafe dynamic SQL concatenation by avoiding direct insertion of user input into SQL statements.

• Implement strict whitelisting for sortable fields to ensure only allowed values are accepted in the `orderBy` parameter.
• Reject suspicious SQL keywords or special characters in sorting parameters to prevent injection.
• Review and update the MyBatis XML files to remove usage of `${orderUtil.orderBy}` and replace it with safe parameter binding.
