CVE-2024-0389 is a SQL Injection vulnerability identified in version 1.0 of the SourceCodester Student Attendance System, specifically within an unspecified function in the attendance_report.php file. The vulnerability arises from improper sanitization or validation of the 'class_id' parameter, which an attacker can manipulate to inject malicious SQL code. This injection can lead to unauthorized access or modification of the underlying database. The vulnerability is classified under CWE-89, which pertains to SQL Injection flaws. The CVSS v3.1 base score is 6.3, indicating a medium severity level. The vector string (AV:A/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L) shows that the attack requires network access with low complexity, no privileges, and no user interaction, affecting confidentiality, integrity, and availability to a limited extent. Although no public exploits are currently known to be actively used in the wild, the exploit details have been publicly disclosed, increasing the risk of exploitation. The vulnerability could allow attackers to extract sensitive student attendance data, alter records, or disrupt the attendance reporting functionality, potentially impacting the reliability and trustworthiness of the system's data. Given that the affected software is a student attendance system, the threat primarily targets educational institutions or organizations managing student attendance data using this specific product version.

For European organizations, particularly educational institutions such as schools, colleges, and universities that deploy the SourceCodester Student Attendance System version 1.0, this vulnerability poses a significant risk. Exploitation could lead to unauthorized disclosure of student attendance records, which may contain personally identifiable information (PII), thereby violating data protection regulations such as the GDPR. Alteration or deletion of attendance data could disrupt administrative processes, affect student evaluations, and undermine institutional integrity. Additionally, availability impacts could cause operational downtime or loss of trust in the system. Since the vulnerability requires no authentication or user interaction and can be exploited remotely over the network, it increases the attack surface. Although the CVSS score is medium, the critical nature of educational data and regulatory compliance requirements elevate the practical impact. Organizations failing to address this vulnerability may face reputational damage, legal consequences, and operational challenges.

To mitigate this vulnerability, European organizations should immediately audit their use of the SourceCodester Student Attendance System version 1.0 and identify any deployments of the affected attendance_report.php component. Since no official patch or update is currently available, organizations should implement the following specific measures: 1) Employ Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting the 'class_id' parameter. 2) Conduct a thorough code review and apply input validation and parameterized queries or prepared statements to sanitize all user inputs, especially the 'class_id' parameter, to prevent injection. 3) Restrict network access to the attendance system to trusted internal networks or VPNs to reduce exposure. 4) Monitor logs for suspicious database query patterns or anomalies related to attendance_report.php access. 5) Educate IT staff and administrators about the vulnerability and encourage prompt incident reporting. 6) Plan for an upgrade or replacement of the affected software version once a vendor patch or secure alternative becomes available. 7) Regularly back up attendance data securely to enable recovery in case of data tampering or loss.
