Root Cause Analysis

The vulnerability stems from insufficient input validation and sanitization in the /login.php file. The application directly concatenates user input from the upass parameter into SQL queries without proper sanitization or prepared statements.

Technical Root Cause:

• Direct string concatenation in SQL queries
• Lack of input validation and sanitization
• Missing prepared statements implementation
• Insufficient parameter binding

3. Proof of Concept
