CVE-2025-14337 is a SQL injection vulnerability identified in the itsourcecode Student Management System version 1.0, specifically within the /new_grade.php endpoint. The vulnerability stems from improper input validation of the 'grade' parameter, which can be manipulated by an unauthenticated remote attacker to inject arbitrary SQL commands. This flaw allows attackers to execute unauthorized queries against the backend database, potentially leading to data leakage, data modification, or denial of service. The vulnerability does not require any authentication or user interaction, making it easier to exploit remotely. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:P) indicates network attack vector, low attack complexity, no privileges or user interaction needed, and partial impacts on confidentiality, integrity, and availability. Although no known exploits are currently active in the wild, the public disclosure increases the risk of exploitation by threat actors. The affected product is primarily used in educational environments to manage student grades and records, making the confidentiality and integrity of student data critical. The lack of available patches necessitates immediate attention to code remediation and deployment of compensating controls to mitigate risk.

For European organizations, particularly educational institutions using the itsourcecode Student Management System, this vulnerability poses significant risks. Exploitation could lead to unauthorized disclosure of sensitive student information, manipulation of academic records, and potential disruption of educational services. Such breaches could violate GDPR regulations, resulting in legal and financial penalties. The integrity of student grades and records is crucial for academic credibility; thus, any tampering could undermine trust in the institution. Additionally, attackers could leverage the vulnerability as a foothold for further network intrusion. The medium CVSS score reflects a moderate but tangible risk, especially given the lack of authentication and user interaction requirements. The impact extends beyond data loss to reputational damage and operational disruption, which are critical concerns for European educational entities.

To mitigate CVE-2025-14337, organizations should immediately conduct a thorough code review of the /new_grade.php file and implement strict input validation and parameterized queries or prepared statements to prevent SQL injection. If source code modification is not immediately feasible, deploying web application firewalls (WAFs) with SQL injection detection rules can provide a temporary protective layer. Network segmentation should be enforced to limit access to the Student Management System from untrusted networks. Continuous monitoring and logging of database queries and application logs can help detect anomalous activities indicative of exploitation attempts. Organizations should also engage with the vendor or community to obtain or develop patches and apply them promptly. Additionally, conducting security awareness training for developers on secure coding practices will help prevent similar vulnerabilities in the future. Finally, regular vulnerability scanning and penetration testing should be integrated into the security lifecycle to identify and remediate such issues proactively.
