CVE-2025-12609 identifies a SQL injection vulnerability in CodeAstro Gym Management System version 1.0, located in the /admin/update-progress.php endpoint. The vulnerability stems from insufficient input validation or sanitization of the id and ini_weight parameters, which are used in SQL queries without proper parameterization. An attacker with authenticated access to the administrative interface can manipulate these parameters to inject arbitrary SQL commands. This can lead to unauthorized reading, modification, or deletion of database records, potentially exposing sensitive user data or corrupting system data. The vulnerability is remotely exploitable but requires high privileges, meaning the attacker must already have administrative credentials or have compromised an account with such privileges. The CVSS 4.0 vector indicates no user interaction is needed, low complexity of attack, and no scope change, with low impact on confidentiality, integrity, and availability individually but combined to a medium overall score of 5.1. Although no exploits are currently observed in the wild, the public disclosure of exploit details increases the risk of exploitation. The lack of vendor patches at the time of publication necessitates immediate mitigation efforts by administrators. This vulnerability highlights the importance of secure coding practices, especially in web applications handling sensitive health and fitness data.

For European organizations, particularly gyms and fitness centers using CodeAstro Gym Management System 1.0, this vulnerability poses a risk of unauthorized access to sensitive customer and operational data. Exploitation could lead to data breaches involving personal health information, membership details, and payment data, potentially violating GDPR and other privacy regulations. Integrity of progress tracking and membership records could be compromised, affecting business operations and customer trust. Availability impacts are likely limited but could occur if database corruption or denial of service results from malicious queries. The requirement for administrative privileges reduces the attack surface but does not eliminate risk, especially if credential theft or insider threats occur. Organizations may face regulatory fines, reputational damage, and operational disruptions if the vulnerability is exploited. The medium severity indicates a moderate but actionable threat that should be addressed promptly to prevent escalation.

1. Apply vendor-provided patches or updates for CodeAstro Gym Management System as soon as they become available. 2. Restrict access to the /admin/update-progress.php endpoint using network segmentation, VPNs, or IP whitelisting to limit exposure to trusted administrators only. 3. Enforce strong authentication mechanisms, including multi-factor authentication (MFA), to reduce the risk of credential compromise. 4. Implement web application firewalls (WAF) with custom rules to detect and block SQL injection attempts targeting the vulnerable parameters. 5. Conduct code reviews and refactor the application to use parameterized queries or prepared statements for all database interactions, eliminating direct concatenation of user inputs. 6. Regularly audit logs for suspicious activity related to administrative functions and SQL errors. 7. Educate administrative users on phishing and credential security to prevent account takeover. 8. Consider deploying database activity monitoring tools to detect anomalous queries indicative of injection attempts.
