CVE-2025-14661 identifies a SQL injection vulnerability in the itsourcecode Student Management System version 1.0, specifically within the /advisers.php file. The vulnerability arises from improper sanitization of the 'sy' parameter, which is susceptible to malicious SQL code injection. This flaw allows remote attackers to execute arbitrary SQL commands on the backend database without requiring authentication or user interaction, as indicated by the CVSS vector (AV:N/AC:L/AT:N/PR:N/UI:N). The vulnerability impacts the confidentiality, integrity, and availability of the system by potentially exposing sensitive student and adviser data, modifying records, or causing denial of service through database corruption. Although no known exploits are currently active in the wild, the public disclosure of the vulnerability increases the risk of exploitation by attackers. The lack of patches or official remediation guidance necessitates that organizations implement immediate mitigations such as input validation, use of prepared statements, and restricting access to the vulnerable endpoint. The vulnerability's medium severity score (6.9) reflects the balance between ease of exploitation and the potential impact on affected systems. Given the critical nature of student data and the operational importance of student management systems, this vulnerability poses a significant risk to educational institutions relying on this software.

For European organizations, particularly educational institutions using the itsourcecode Student Management System, this vulnerability could lead to unauthorized disclosure of sensitive student and staff information, including personal identifiers and academic records. Data integrity may be compromised through unauthorized modification or deletion of records, potentially disrupting administrative operations and affecting student outcomes. Availability of the system could be impacted if attackers exploit the vulnerability to cause database errors or crashes, leading to downtime and loss of access to critical services. Such incidents could result in regulatory non-compliance under GDPR due to data breaches, leading to financial penalties and reputational damage. The remote, unauthenticated nature of the exploit increases the likelihood of attacks, especially in environments where the system is exposed to the internet or insufficiently segmented networks. The public disclosure of the vulnerability further elevates the risk, as attackers may develop and deploy automated exploit tools targeting vulnerable installations across Europe.

Organizations should immediately audit their deployment of the itsourcecode Student Management System to identify affected versions. Since no official patch is currently available, developers or administrators must implement input validation and sanitization for the 'sy' parameter in /advisers.php, ideally replacing vulnerable code with parameterized queries or prepared statements to prevent SQL injection. Network-level controls should be applied to restrict access to the /advisers.php endpoint, limiting it to trusted internal IP addresses or VPN users. Web application firewalls (WAFs) can be configured to detect and block SQL injection attempts targeting this parameter. Continuous monitoring of logs for suspicious query patterns or errors related to SQL injection should be established. Organizations should also prepare incident response plans for potential data breaches and consider isolating or temporarily disabling the vulnerable system until mitigations are in place. Finally, maintaining regular backups of the database will aid recovery in case of data corruption or loss.
