CVE-2024-42571 is a critical SQL injection vulnerability identified in the School Management System software, specifically in the insertattendance.php file via the 'medium' parameter. SQL injection (CWE-89) occurs when untrusted input is improperly sanitized, allowing attackers to inject malicious SQL queries into the backend database. This vulnerability enables remote attackers to execute arbitrary SQL commands without authentication or user interaction, potentially leading to unauthorized data access, data modification, or complete system compromise. The vulnerability has a CVSS 3.1 base score of 9.8, indicating critical severity with network attack vector, low attack complexity, no privileges required, and no user interaction. The impact includes full confidentiality loss, integrity compromise, and availability disruption of the affected system. Although no patches or exploit code are currently publicly available, the vulnerability's nature and severity make it a prime target for attackers once weaponized. The affected software is used in educational institutions for managing attendance and other school-related data, making the data sensitive and the impact significant. The vulnerability was reserved and published in August 2024, with no specific affected versions listed, suggesting it may affect multiple or all versions of the software. The lack of patch links indicates that remediation may still be pending or that users must implement manual mitigations.

The potential impact of CVE-2024-42571 is severe for organizations using the affected School Management System. Exploitation can lead to unauthorized disclosure of sensitive student and staff data, including personal identifiable information (PII), attendance records, and potentially other educational records. Attackers could alter attendance data, disrupt school operations, or escalate attacks to compromise the entire network if the database is connected to other critical systems. The availability of the system could be impacted through destructive SQL commands or denial-of-service conditions. Given the critical CVSS score and the lack of required authentication, the vulnerability poses a high risk of exploitation, especially in environments where the system is exposed to the internet or insufficiently segmented. Educational institutions worldwide could face reputational damage, regulatory penalties, and operational disruptions if this vulnerability is exploited.

To mitigate CVE-2024-42571, organizations should immediately review and sanitize all inputs to the insertattendance.php script, especially the 'medium' parameter. Implement parameterized queries or prepared statements to prevent SQL injection attacks. If patches become available from the vendor, apply them promptly. In the absence of official patches, consider deploying Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting this parameter. Restrict database user permissions to the minimum necessary to limit the impact of any successful injection. Conduct thorough code audits of the application to identify and remediate other potential injection points. Monitor database logs and application logs for unusual queries or errors indicative of exploitation attempts. Network segmentation should be enforced to isolate the School Management System from critical infrastructure. Finally, educate development teams on secure coding practices to prevent similar vulnerabilities in the future.
