CVE-2024-42567 identifies a critical SQL injection vulnerability in a School Management System, specifically triggered through the 'sid' parameter in the /search.php?action=2 endpoint. SQL injection (CWE-89) vulnerabilities occur when user-supplied input is improperly sanitized before being included in SQL queries, allowing attackers to manipulate the database query logic. In this case, the vulnerability allows unauthenticated remote attackers to inject malicious SQL commands directly, leading to unauthorized data access, modification, or deletion. The CVSS 3.1 score of 9.8 indicates a critical severity with network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and impacts on confidentiality, integrity, and availability (C:H/I:H/A:H). This means an attacker can exploit the vulnerability remotely without any authentication or user action, potentially compromising the entire database. The vulnerability was discovered in a specific commit (bae5aa) of the School Management System, but affected versions are not explicitly listed. No patches or known exploits are currently documented, but the risk remains high due to the nature of SQL injection. The vulnerability could allow attackers to extract sensitive student and staff data, alter records, or disrupt system operations, severely impacting educational institutions relying on this software. The lack of authentication and user interaction requirements makes this vulnerability particularly dangerous and easy to exploit. The vulnerability was published on August 20, 2024, and is assigned by MITRE with data version 5.1.

The impact of CVE-2024-42567 is severe for organizations using the affected School Management System. Exploitation can lead to unauthorized disclosure of sensitive educational data, including student records, grades, and personal information, violating privacy regulations such as FERPA or GDPR. Attackers could also modify or delete critical data, disrupting school operations and potentially causing loss of trust and reputational damage. The availability of the system could be compromised through destructive SQL commands, leading to downtime and operational delays. Since the vulnerability requires no authentication or user interaction, it significantly increases the attack surface and risk of automated exploitation by threat actors. Educational institutions worldwide, especially those with limited cybersecurity resources, could face data breaches, compliance penalties, and operational interruptions. The vulnerability also poses a risk of lateral movement if the compromised database credentials are reused or connected to other internal systems. The absence of known exploits currently provides a window for proactive mitigation, but the critical CVSS score underscores the urgency of addressing this flaw.

To mitigate CVE-2024-42567, organizations should immediately audit the affected School Management System for the vulnerable /search.php?action=2 endpoint and the 'sid' parameter. Implement strict input validation and sanitization to reject or properly escape all user-supplied data before database queries. Transition all database interactions to use parameterized queries or prepared statements to prevent injection. If source code access is available, review and refactor the vulnerable commit or module to eliminate direct concatenation of user input in SQL commands. Deploy Web Application Firewalls (WAFs) with SQL injection detection and blocking rules as a compensating control until patches are available. Monitor database logs and application logs for unusual query patterns or error messages indicative of injection attempts. Restrict database user privileges to the minimum necessary to limit damage if exploitation occurs. Educate development teams on secure coding practices to prevent future injection flaws. Coordinate with the software vendor or community to obtain or develop patches and apply them promptly. Finally, conduct penetration testing and vulnerability scanning regularly to detect similar issues proactively.
