CVE-2025-11590 identifies a SQL injection vulnerability in CodeAstro Gym Management System version 1.0, specifically within the /admin/equipment-entry.php file. The vulnerability arises from improper sanitization of the 'ename' parameter, which is used in SQL queries without adequate validation or parameterization. An attacker can remotely send crafted input to this parameter to manipulate the SQL query executed by the backend database, potentially allowing unauthorized data retrieval, modification, or deletion. The attack vector requires no user interaction and no authentication, making it highly accessible to remote attackers. The CVSS 4.0 score of 5.3 (medium severity) reflects the moderate impact on confidentiality, integrity, and availability, with low complexity and no privileges required. Although no active exploits have been reported in the wild, the availability of public exploit code increases the risk of exploitation. The vulnerability affects only version 1.0 of the product, which is used by gym management entities to handle equipment data and possibly other sensitive operational information. The lack of patches or official remediation guidance increases the urgency for organizations to implement compensating controls. This vulnerability could lead to unauthorized access to sensitive data, data corruption, or denial of service, impacting operational continuity and data privacy.

For European organizations using CodeAstro Gym Management System 1.0, this vulnerability poses a risk of unauthorized access to sensitive gym management data, including equipment inventories and potentially customer or operational information. Exploitation could lead to data breaches, data manipulation, or service disruptions, affecting business operations and customer trust. Given the remote and unauthenticated nature of the attack, threat actors can easily target exposed systems over the internet. This could also lead to compliance issues under GDPR if personal data is compromised. The fitness industry in Europe, which is growing and increasingly reliant on digital management systems, may face operational and reputational damage. Additionally, attackers could leverage this vulnerability as a foothold for further network intrusion or lateral movement within organizations. The medium severity rating suggests moderate but tangible risks that require timely attention to prevent escalation.

Since no official patches are currently available, European organizations should immediately implement strict input validation and sanitization on the 'ename' parameter to prevent SQL injection. Employing parameterized queries or prepared statements in the application code is critical to eliminate injection vectors. Deploying a Web Application Firewall (WAF) with rules specifically targeting SQL injection patterns can provide an effective temporary barrier against exploitation attempts. Restricting access to the /admin/equipment-entry.php endpoint via network segmentation or VPN access can reduce exposure. Regularly monitoring logs for suspicious SQL query patterns or unusual database activity will aid early detection. Organizations should engage with CodeAstro for updates or patches and plan for prompt application once released. Conducting security audits and penetration testing focused on injection vulnerabilities will help identify and remediate similar issues. Finally, ensure backups of critical data are maintained to enable recovery in case of data corruption or loss.
