CVE-2025-11588 identifies a SQL injection vulnerability in CodeAstro Gym Management System version 1.0, located in the /customer/index.php file. The vulnerability arises from improper sanitization of the 'fullname' parameter, which is directly used in SQL queries. An attacker can remotely craft malicious input to manipulate the SQL statement, potentially extracting sensitive information, modifying data, or causing denial of service by corrupting database operations. The vulnerability does not require authentication or user interaction, increasing its risk profile. The CVSS 4.0 base score is 5.3 (medium), reflecting the network attack vector, low complexity, no privileges required, and no user interaction needed, but limited impact on confidentiality, integrity, and availability. Although no active exploitation has been reported, the availability of a public exploit increases the likelihood of future attacks. The vulnerability affects only version 1.0 of the product, which is used primarily by gym and fitness center operators to manage customer data and operations. The lack of an official patch at the time of disclosure necessitates immediate mitigation efforts by users. This vulnerability highlights the critical need for secure coding practices, especially input validation and use of parameterized queries to prevent injection flaws.

For European organizations operating gyms or fitness centers using CodeAstro Gym Management System 1.0, this vulnerability poses a significant risk to the confidentiality and integrity of customer data, including personal information stored in the database. Exploitation could lead to unauthorized data disclosure, data tampering, or disruption of gym management services, impacting business continuity and customer trust. Regulatory compliance risks are also notable, as data breaches involving personal data could violate GDPR requirements, leading to legal penalties and reputational damage. The remote and unauthenticated nature of the attack vector means that attackers can exploit the vulnerability without insider access, increasing the threat surface. The availability impact, while rated low, could still result in service interruptions if the database is corrupted or overwhelmed by injection attacks. Overall, the vulnerability could disrupt operations and expose sensitive data, making it a critical concern for affected European entities.

To mitigate CVE-2025-11588, organizations should immediately implement input validation and sanitization on the 'fullname' parameter and any other user-supplied inputs. Employing parameterized queries or prepared statements in the database access code is essential to prevent SQL injection. Since no official patch is currently available, consider deploying a Web Application Firewall (WAF) with rules to detect and block SQL injection attempts targeting the vulnerable endpoint. Restrict network access to the management system to trusted IP ranges where possible, and monitor logs for suspicious activity related to the /customer/index.php page. Conduct a thorough code review of the application to identify and remediate other potential injection points. Additionally, ensure regular backups of the database are maintained to enable recovery in case of data corruption. Finally, plan for an update or patch deployment from the vendor once available and educate staff on the risks and detection of SQL injection attacks.
