CVE-2025-9840 is a medium-severity SQL Injection vulnerability identified in version 1.0 of the itsourcecode Sports Management System. The vulnerability exists in an unspecified function within the /Admin/gametype.php file, where manipulation of the 'code' argument allows an attacker to inject malicious SQL commands. This flaw enables remote exploitation without requiring user interaction or authentication, as indicated by the CVSS vector (AV:N/AC:L/AT:N/UI:N/PR:L). The vulnerability impacts the confidentiality, integrity, and availability of the underlying database, potentially allowing attackers to read, modify, or delete sensitive data stored by the Sports Management System. Although the CVSS score is moderate at 5.3, the presence of publicly available exploit code increases the risk of exploitation. The vulnerability does not require complex attack conditions or user involvement, making it accessible to attackers with low privileges. The lack of a patch or mitigation link suggests that the vendor has not yet released an official fix, increasing the urgency for organizations to implement compensating controls. The vulnerability affects only version 1.0 of the product, so organizations running this specific version are at risk. Given the system's role in managing sports-related data, the impact could extend to operational disruptions and data breaches involving user or organizational information.

For European organizations using the itsourcecode Sports Management System version 1.0, this vulnerability poses a significant risk to data confidentiality and system integrity. Successful exploitation could lead to unauthorized access to sensitive sports management data, including schedules, player information, and possibly financial or personal data if stored within the system. This could result in data breaches subject to GDPR regulations, leading to legal and financial penalties. Operationally, attackers could alter or delete critical data, disrupting sports event management and related services. The remote and unauthenticated nature of the exploit increases the likelihood of attacks, especially in environments where the system is exposed to the internet or insufficiently segmented. The availability of public exploit code further elevates the threat, potentially attracting opportunistic attackers. European organizations involved in sports management, event coordination, or related sectors should consider the reputational damage and operational downtime that could arise from exploitation. Additionally, if the system integrates with other internal platforms, the compromise could serve as a pivot point for broader network intrusion.

Given the absence of an official patch, European organizations should implement immediate compensating controls. First, restrict external access to the /Admin/gametype.php endpoint by applying network-level controls such as firewalls or VPNs to limit access to trusted administrators only. Implement web application firewalls (WAFs) with custom rules to detect and block SQL injection payloads targeting the 'code' parameter. Conduct thorough input validation and sanitization on all user-supplied inputs, especially the 'code' argument, to prevent injection attacks. Monitor logs for suspicious SQL queries or repeated access attempts to the vulnerable endpoint. If possible, upgrade to a newer, patched version of the software once available or consider alternative solutions if the vendor does not provide timely remediation. Additionally, conduct regular security assessments and penetration tests focusing on web application vulnerabilities. Educate administrators on the risks and signs of exploitation to enable rapid incident response. Finally, ensure that database accounts used by the application have the least privileges necessary to limit the impact of a potential SQL injection attack.
