CVE-2025-14209 is a SQL injection vulnerability identified in Campcodes School File Management System version 1.0. The vulnerability resides in the /update_query.php script, where the stud_id parameter is improperly sanitized, allowing an attacker to inject malicious SQL code. This injection flaw enables remote attackers to manipulate backend database queries without requiring authentication or user interaction, potentially leading to unauthorized data disclosure, data modification, or even complete compromise of the database. The vulnerability has a CVSS 4.0 base score of 6.9, reflecting medium severity due to its network attack vector, low complexity, and no privileges or user interaction needed. The impact on confidentiality, integrity, and availability is limited but non-negligible, as attackers can access or alter sensitive student records or other educational data. Although no active exploits have been reported in the wild, the public availability of exploit code increases the likelihood of exploitation attempts. The lack of vendor patches or official remediation guidance necessitates immediate defensive measures by users of the affected software. This vulnerability highlights the critical need for secure coding practices, especially input validation and use of parameterized queries in web applications managing sensitive educational data.

For European organizations, particularly educational institutions using Campcodes School File Management System 1.0, this vulnerability poses a risk of unauthorized access to sensitive student and administrative data. Exploitation could lead to data breaches involving personal identifiable information (PII), academic records, and potentially financial information. Integrity of records could be compromised, affecting trust and compliance with data protection regulations such as GDPR. Availability impact is limited but could occur if attackers execute destructive SQL commands. The exposure of such vulnerabilities could damage institutional reputation and result in regulatory penalties. Given the remote and unauthenticated nature of the exploit, attackers can target systems over the internet, increasing the risk for organizations with externally accessible management portals. The medium severity score reflects a moderate but actionable threat that requires timely mitigation to prevent escalation.

Organizations should immediately audit their use of Campcodes School File Management System version 1.0 and isolate any exposed instances. Since no official patch is currently available, implement the following mitigations: 1) Apply strict input validation and sanitization on the stud_id parameter and any other user inputs to prevent injection. 2) Refactor the vulnerable code to use parameterized queries or prepared statements to eliminate direct SQL concatenation. 3) Restrict network access to the management system, allowing only trusted IP addresses or VPN connections. 4) Monitor logs for unusual database queries or access patterns indicative of injection attempts. 5) Conduct regular security assessments and penetration testing focused on injection flaws. 6) Educate developers and administrators on secure coding and configuration best practices. 7) Prepare incident response plans to quickly address any detected exploitation. 8) Engage with the vendor for updates or patches and plan for software upgrades to more secure versions when available.
