CVE-2025-9596 is a SQL Injection vulnerability identified in version 1.0 of the itsourcecode Sports Management System, specifically affecting an unspecified function within the /login.php file. The vulnerability arises from improper sanitization or validation of the 'User' argument, allowing an attacker to inject malicious SQL code remotely without requiring authentication or user interaction. This flaw enables an adversary to manipulate backend database queries, potentially leading to unauthorized data access, data modification, or disruption of service. The vulnerability has a CVSS 4.0 base score of 6.9, indicating a medium severity level, with an attack vector of network (remote exploitation), low attack complexity, no privileges or user interaction needed, and limited impact on confidentiality, integrity, and availability. Although no public exploits are currently known to be actively used in the wild, the vulnerability has been publicly disclosed, increasing the risk of exploitation by threat actors. The lack of available patches or mitigations from the vendor further elevates the urgency for organizations using this software to implement compensating controls.

For European organizations utilizing the itsourcecode Sports Management System 1.0, this SQL Injection vulnerability poses significant risks. Exploitation could lead to unauthorized disclosure of sensitive data such as user credentials, personal information of athletes or staff, and organizational data. Data integrity could be compromised through unauthorized modifications, potentially affecting scheduling, results, or financial records. Availability impacts could arise if attackers execute destructive SQL commands or cause database corruption, disrupting sports management operations. Given the remote and unauthenticated nature of the exploit, attackers can target systems over the internet, increasing exposure. Organizations in sectors such as sports clubs, educational institutions, and event management that rely on this system may face operational disruptions, reputational damage, and regulatory compliance issues under GDPR if personal data is compromised.

Since no official patches or updates are currently available for this vulnerability, European organizations should implement immediate compensating controls. These include deploying web application firewalls (WAFs) with rules specifically designed to detect and block SQL injection attempts targeting the /login.php endpoint and the 'User' parameter. Input validation and sanitization should be enforced at the application layer if source code access is possible, employing parameterized queries or prepared statements to prevent injection. Network segmentation and restricting access to the Sports Management System to trusted IP ranges can reduce exposure. Continuous monitoring of logs for anomalous SQL queries or failed login attempts can help detect exploitation attempts early. Organizations should also plan to upgrade or replace the vulnerable software once a vendor patch or a secure alternative becomes available. Regular security assessments and penetration testing focusing on injection flaws are recommended to ensure ongoing protection.
