• Data Breach: Potential for unauthorized access to sensitive student and staff data.
• Data Integrity: Compromise of data integrity leading to incorrect attendance records.
• System Compromise: Possible full system compromise if administrative commands are executed.

Long-Term Impact:

• Reputation Damage: Loss of trust in the SMS and the educational institution.
• Regulatory Compliance: Potential violation of data protection regulations leading to legal consequences.
• Increased Attack Surface: Other systems integrated with the SMS may also be at risk.

6. Technical Details for Security Professionals

Vulnerability Details:

• Vulnerable Component: insertattendance.php
• Vulnerable Parameter: medium
• Exploit Example:

  medium=1'; DROP TABLE students; --
  

Detection Methods:

• Static Analysis: Use static analysis tools to identify SQL injection points in the codebase.

• Log Analysis: Review logs for unusual SQL queries or error messages indicating SQL injection attempts.

Mitigation Code Example:

// Using prepared statements in PHP
$stmt = $pdo->prepare("INSERT INTO attendance (medium, student_id, date) VALUES (:medium, :student_id, :date)");
$stmt->bindParam(':medium', $medium);
$stmt->bindParam(':student_id', $student_id);
$stmt->bindParam(':date', $date);
$stmt->execute();
