• Attack Vector (AV:N): Network, meaning the vulnerability is exploitable remotely.
• Attack Complexity (AC:L): Low, indicating that the attack does not require specialized conditions.
• Privileges Required (PR:N): None, meaning no privileges are needed to exploit the vulnerability.
• User Interaction (UI:N): None, indicating that no user interaction is required.
• Scope (S:U): Unchanged, meaning the vulnerability affects the same security scope.
• Confidentiality (C:H): High, indicating a complete loss of confidentiality.
• Integrity (I:H): High, indicating a complete loss of integrity.
• Availability (A:H): High, indicating a complete loss of availability.

Given these metrics, the vulnerability poses a significant risk to the confidentiality, integrity, and availability of the affected systems.

2. Potential Attack Vectors and Exploitation Methods

The primary attack vector is through the id parameter in the URL /AttendanceMonitoring/department/index.php. An attacker can exploit this vulnerability by sending a specially crafted SQL query to the server. Common exploitation methods include:

• Union-Based SQL Injection: Combining the results of two SELECT statements to extract data.
• Error-Based SQL Injection: Inducing database errors to gather information about the database structure.
• Blind SQL Injection: Using true/false responses to extract data without direct feedback from the database.

Example of a crafted query:

/AttendanceMonitoring/department/index.php?id=1' OR '1'='1

3. Affected Systems and Software Versions

The vulnerability affects the following systems and software versions:

• School Event Management System: Version 1.0
• School Attendance Monitoring System: Version 1.0

Both systems are developed by the vendor Janobe.
