CVE-2025-9840 is a medium-severity SQL Injection vulnerability identified in version 1.0 of the itsourcecode Sports Management System, specifically within an unknown function in the /Admin/gametype.php file. The vulnerability arises from improper sanitization or validation of the 'code' parameter, which can be manipulated remotely by an unauthenticated attacker to inject malicious SQL commands. This injection flaw allows attackers to interfere with the application's database queries, potentially leading to unauthorized data access, data modification, or deletion. The vulnerability does not require user interaction and can be exploited over the network without authentication, increasing its risk profile. The CVSS 4.0 vector indicates low complexity (AC:L), no privileges required (PR:L), no user interaction (UI:N), and partial impacts on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). Although no known exploits are currently reported in the wild, the exploit code has been publicly disclosed, which could facilitate exploitation by threat actors. The lack of available patches or mitigations from the vendor further elevates the risk for users of this software version. Given the nature of sports management systems, which often store sensitive user and organizational data, exploitation could lead to data breaches, loss of data integrity, and service disruptions.

For European organizations using the itsourcecode Sports Management System 1.0, this vulnerability poses a tangible risk to the confidentiality, integrity, and availability of their data and services. Sports organizations, clubs, and related entities that rely on this system could face unauthorized disclosure of sensitive information such as user credentials, personal data, or internal operational details. Data integrity could be compromised by unauthorized modification or deletion of records, potentially disrupting event management, scheduling, or financial transactions. Availability impacts could arise if attackers leverage the injection to execute destructive queries or cause database crashes, leading to service outages. Additionally, regulatory compliance risks exist under GDPR, as data breaches involving personal data must be reported and can result in significant penalties. The remote and unauthenticated nature of the exploit increases the attack surface, making it easier for malicious actors to target vulnerable installations across Europe.

Given the absence of official patches, European organizations should implement immediate compensating controls. First, restrict access to the /Admin/gametype.php endpoint by IP whitelisting or VPN access to limit exposure. Employ Web Application Firewalls (WAFs) with rules tuned to detect and block SQL injection patterns targeting the 'code' parameter. Conduct thorough input validation and sanitization on all user-supplied data, especially parameters passed to SQL queries, ideally using parameterized queries or prepared statements to prevent injection. Monitor logs for suspicious database query patterns or repeated failed attempts to exploit the vulnerability. Organizations should also consider isolating the affected system within segmented network zones to reduce lateral movement risk. Finally, engage with the vendor or community to obtain or develop patches and plan for an upgrade path to a fixed version once available. Regular backups of the database should be maintained to enable recovery in case of data corruption or loss.
