SQL injection vulnerability in user login form

Code Snippet:

query = `SELECT * FROM users WHERE username='${username}' AND password='${password}'`
Diagnosis
By Dr. Security-Guard (Security Expert)

The provided code snippet constructs an SQL query by directly concatenating user-supplied `username` and `password` values into the query string. This method is highly vulnerable to SQL injection attacks. An attacker can input specially crafted strings (e.g., `' OR '1'='1`) into the username or password fields, altering the intended SQL query logic. This can lead to unauthorized access, data exfiltration, or even data modification/deletion, bypassing authentication mechanisms.

Treatment Plan

The primary treatment is to replace string concatenation with parameterized queries (also known as prepared statements). This ensures that user-supplied data is treated as literal values, not as executable SQL code. The database driver separates the SQL command from the data, preventing malicious input from altering the query structure. Additionally, input validation (e.g., checking for expected data types, length constraints, and sanitizing special characters) should be applied on the server-side as a defense-in-depth measure, though it does not replace parameterized queries for preventing SQL injection.
