CVE-2025-9156 is a SQL Injection vulnerability identified in version 1.0 of the itsourcecode Sports Management System, specifically within an unspecified function in the /Admin/sports.php file. The vulnerability arises from improper sanitization or validation of the 'code' argument, which allows an attacker to manipulate SQL queries executed by the application. This flaw enables remote attackers to inject arbitrary SQL commands 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 underlying database, as attackers can potentially extract sensitive data, modify or delete records, or disrupt application functionality. The CVSS score of 6.9 (medium severity) reflects the moderate impact and ease of exploitation. Although no public exploit is currently known to be actively used in the wild, the exploit code has been made publicly available, increasing the risk of exploitation by opportunistic attackers. The vulnerability does not require privileges or user interaction, making it more accessible to remote attackers. 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 or monitor for exploitation attempts. The vulnerability affects only version 1.0 of the Sports Management System, which may limit the scope depending on the deployment footprint of this specific version.

For European organizations using the itsourcecode Sports Management System 1.0, this SQL Injection vulnerability poses significant risks. Exploitation can lead to unauthorized access to sensitive sports management data, including user credentials, schedules, financial transactions, or personal information of athletes and staff. Data breaches could result in regulatory non-compliance under GDPR, leading to legal penalties and reputational damage. Integrity violations could disrupt operations, causing incorrect scheduling, resource allocation, or financial reporting. Availability impacts could result from database corruption or denial of service, affecting the continuity of sports management activities. The remote and unauthenticated nature of the exploit increases the likelihood of attacks, especially if the system is exposed to the internet or poorly segmented within internal networks. European organizations with public-facing or inadequately secured deployments are particularly vulnerable. Additionally, the public availability of exploit code lowers the barrier for attackers, increasing the threat landscape. The medium severity rating suggests that while the vulnerability is serious, it may not lead to full system compromise without additional factors, but the potential for data leakage and operational disruption remains substantial.

Given the absence of an official patch, European organizations should prioritize immediate mitigation steps: 1) Implement Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting the 'code' parameter in /Admin/sports.php. 2) Restrict access to the /Admin directory by IP whitelisting or VPN-only access to reduce exposure to remote attackers. 3) Conduct thorough input validation and sanitization on all user-supplied data, especially the 'code' parameter, using parameterized queries or prepared statements if source code access is available. 4) Monitor application and database logs for anomalous queries or error messages indicative of injection attempts. 5) Isolate the Sports Management System within a segmented network zone to limit lateral movement if compromised. 6) Engage with the vendor to obtain or request an official patch or updated version addressing this vulnerability. 7) Plan for an urgent upgrade or migration to a patched version once available. 8) Educate administrators and users about the risks and signs of exploitation attempts. These targeted mitigations go beyond generic advice by focusing on access controls, monitoring, and immediate protective measures tailored to the vulnerability's characteristics.
