CVE-2025-14258 identifies a SQL injection vulnerability in the itsourcecode Student Management System version 1.0, located in the /newsubject.php script. The vulnerability arises from improper sanitization of the 'sub' parameter, which is directly incorporated into SQL queries without adequate validation or parameterization. This allows remote attackers to inject malicious SQL code, potentially enabling unauthorized reading, modification, or deletion of database records. The attack vector is network accessible without authentication or user interaction, making exploitation feasible by any remote adversary. 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 low complexity and no privileges required, with partial impacts on confidentiality, integrity, and availability. Although no known exploits are currently active in the wild, the public disclosure of the vulnerability details increases the likelihood of exploitation attempts. The affected product is primarily used in educational environments to manage student data, making the confidentiality and integrity of sensitive information a critical concern. Lack of available patches necessitates immediate mitigation through secure coding practices and monitoring.

For European organizations, particularly educational institutions using the itsourcecode Student Management System 1.0, this vulnerability poses a significant risk of unauthorized access to sensitive student data, including personal information and academic records. Exploitation could lead to data breaches, loss of data integrity, and potential disruption of educational services. The ability to manipulate database queries remotely without authentication increases the attack surface and risk of widespread compromise. This could result in regulatory non-compliance under GDPR due to exposure of personal data, leading to legal and financial repercussions. Additionally, reputational damage and loss of trust among students and stakeholders are likely consequences. The medium severity rating reflects the balance between exploitability and impact, but the critical nature of educational data elevates the practical risk for affected entities.

Organizations should immediately audit their use of the itsourcecode Student Management System version 1.0 and restrict external access to the /newsubject.php endpoint where feasible. Implement strict input validation and sanitization on the 'sub' parameter to prevent injection of malicious SQL code. Refactor the application code to use parameterized queries or prepared statements to eliminate direct concatenation of user inputs into SQL commands. Deploy Web Application Firewalls (WAFs) with rules targeting SQL injection patterns to provide an additional layer of defense. Monitor logs for unusual database query patterns or repeated access attempts to the vulnerable endpoint. If possible, isolate the affected system within segmented network zones to limit exposure. Engage with the vendor or community to obtain patches or updates addressing this vulnerability. Finally, conduct security awareness training for developers to prevent similar issues in future releases.
