Fix SQL Injection Vulnerability by Parameterizing the customerId in Scala's CustomerController.

[zeropath-ai]

Summary

"""

• The Vulnerability Description: The application was vulnerable to SQL injection because it constructed SQL queries by directly concatenating the customerId input into the query without sanitization, allowing attackers to inject arbitrary SQL commands.
• This Fix: The patched code now uses a parameterized query to securely include the customerId by using a placeholder :id, which prevents potential SQL injections.
• The Cause of the Issue: The vulnerability was caused by the practice of directly appending user input (customerId) into the SQL query string, creating an entry point for malicious SQL injections.
• The Patch Implementation: The patch converts the SQL query to a parameterized format with :id as a placeholder, then maps the customerId input to this placeholder using query.setParameter("id", customerId), ensuring safe execution of SQL commands.
