Comprehensive Technical Analysis of EUVD-2024-35112

1. Vulnerability Assessment and Severity Evaluation

Vulnerability Description: The EUVD entry EUVD-2024-35112 describes a SQL injection vulnerability in the /view/find_friends.php script of Campcodes Complete Web-Based School Management System version 1.0. This vulnerability allows an attacker to execute arbitrary SQL commands via the my_index parameter.

Severity Evaluation: The vulnerability has a CVSS Base Score of 9.8, which is considered critical. The CVSS vector CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H indicates the following:

• Attack Vector (AV): Network (N)
• Attack Complexity (AC): Low (L)
• Privileges Required (PR): None (N)
• User Interaction (UI): None (N)
• Scope (S): Unchanged (U)
• Confidentiality (C): High (H)
• Integrity (I): High (H)
• Availability (A): High (H)

This high severity score underscores the critical nature of the vulnerability, which can lead to significant data breaches, unauthorized access, and potential system compromise.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Network-Based Attacks: Since the attack vector is network-based, an attacker can exploit this vulnerability remotely without needing local access.
• SQL Injection: The primary attack method involves injecting malicious SQL code into the my_index parameter to manipulate the database queries executed by the application.

Exploitation Methods:

• Data Exfiltration: Attackers can extract sensitive information from the database, including student records, personal information, and administrative data.
• Data Manipulation: Attackers can alter database entries, leading to integrity issues.
• Unauthorized Access: Attackers can gain unauthorized access to the system, potentially leading to further exploitation and lateral movement within the network.

3. Affected Systems and Software Versions

Affected Systems:

• Campcodes Complete Web-Based School Management System version 1.0

Software Versions:

• Specifically, the vulnerability affects version 1.0 of the Campcodes School Management System.

4. Recommended Mitigation Strategies

Immediate Mitigation:

• Patching: Apply the latest security patches provided by the vendor to mitigate the vulnerability.
• Input Validation: Implement strict input validation and sanitization for the my_index parameter to prevent SQL injection.
• Parameterized Queries: Use parameterized queries or prepared statements to ensure that SQL commands are executed safely.
