🔴 SQL Injection vulnerability via string concatenation

The vulnerableMethod directly concatenates userInput into a SQL query string without any sanitization or parameterization:

String query = "SELECT * FROM users WHERE name = '" + userInput + "'";
stmt.executeQuery(query);

This allows an attacker to inject arbitrary SQL commands. For example, if userInput is '; DROP TABLE users; --, the resulting query becomes:

SELECT * FROM users WHERE name = ''; DROP TABLE users; --'

Impact: An attacker can read, modify, or delete data from the database, potentially gaining full control of the database server.

Expected: Use PreparedStatement with parameterized queries to prevent SQL injection.

Recommendation: Replace with PreparedStatement: PreparedStatement pstmt = conn.prepareStatement("SELECT * FROM users WHERE name = ?"); pstmt.setString(1, userInput); pstmt.executeQuery();

🔴 Comparing two different random values instead of the same value

The buggyMethod compares two separate calls to secureRandom.nextInt():

if (secureRandom.nextInt() == secureRandom.nextInt()) {
    return 1;
}

Each call to nextInt() generates a new independent random number. This means the comparison is between two different random values, not comparing a value to itself.

Actual behavior: The condition will be true only when both random calls happen to return the same value by chance (probability ~1 in 2^32 for int range), making the method almost always return 0.

Expected behavior: If the intent was to check if a random value equals itself (always true), a single value should be stored: int val = secureRandom.nextInt(); if (val == val). If the intent was to compare two random values, this is correct but the logic seems suspicious.

Impact: The method has unpredictable and likely unintended behavior.

Recommendation: Store the random value in a variable before comparison if comparing to itself was intended: int val = secureRandom.nextInt(); if (val == val)
