CVE-2025-14337 identifies a SQL injection vulnerability in the itsourcecode Student Management System version 1.0, specifically within the /new_grade.php endpoint. The vulnerability stems from insufficient input validation or sanitization of the 'grade' parameter, which is directly used in SQL queries. This flaw allows remote attackers to craft malicious input that alters the intended SQL command structure, potentially enabling unauthorized data retrieval, modification, or deletion. The attack vector is network-based, requiring no authentication or user interaction, which significantly lowers the barrier for exploitation. The CVSS 4.0 score of 6.9 reflects a medium severity, considering the vulnerability's impact on confidentiality, integrity, and availability, combined with its ease of exploitation. Although no known exploits have been observed in the wild, the public disclosure of the vulnerability increases the likelihood of exploitation attempts. The lack of available patches at the time of disclosure necessitates immediate mitigation strategies. This vulnerability poses a significant risk to educational institutions relying on this software, as attackers could access sensitive student data or disrupt academic operations.

For European organizations, particularly educational institutions using the itsourcecode Student Management System, this vulnerability could lead to unauthorized access to sensitive student records, including grades and personal information, compromising confidentiality. Integrity of academic data could be undermined by unauthorized modifications, potentially affecting student evaluations and institutional credibility. Availability could also be impacted if attackers execute destructive SQL commands, leading to denial of service or data loss. The breach of sensitive educational data may also result in regulatory penalties under GDPR due to inadequate protection of personal data. Furthermore, reputational damage and loss of trust from students, parents, and staff could have long-term consequences. The ease of remote exploitation without authentication increases the urgency for European organizations to address this vulnerability promptly to avoid potential data breaches and operational disruptions.

European organizations should immediately implement strict input validation and sanitization for all user-supplied data, especially the 'grade' parameter in the /new_grade.php endpoint. Employ parameterized queries or prepared statements to prevent SQL injection attacks. Monitor network traffic for suspicious activity targeting the Student Management System. Restrict access to the application to trusted networks or VPNs where possible. Conduct thorough code reviews and security testing to identify and remediate similar vulnerabilities. Maintain regular backups of critical data to enable recovery in case of data corruption or loss. Engage with the vendor or community to obtain patches or updates as soon as they become available. Additionally, implement web application firewalls (WAFs) with SQL injection detection rules tailored to this vulnerability. Educate IT staff and users about the risks and signs of exploitation attempts. Finally, ensure compliance with GDPR by documenting mitigation efforts and breach response plans.
