Technical details

The vulnerability exists in student_signup.php and teacher_signup.php, where user-supplied form fields are directly concatenated into SQL SELECT and UPDATE queries without sanitization or parameterized statements. By injecting SQL syntax (e.g., ' OR 1=1 -- -) into the firstname parameter, an attacker bypasses account verification logic and causes the UPDATE to modify any account or all accounts. No authentication is required; the attack is initiated remotely via HTTP POST.
