CVE-2025-12609 is a SQL injection vulnerability identified in version 1.0 of the CodeAstro Gym Management System, specifically within the /admin/update-progress.php endpoint. The vulnerability stems from insufficient input validation and sanitization of the 'id' and 'ini_weight' parameters, which are used in SQL queries without proper escaping or parameterization. This flaw allows an attacker with administrative privileges to inject malicious SQL code remotely, potentially altering database queries to read, modify, or delete data. The vulnerability does not require user interaction but does require the attacker to have high privileges (PR:H), indicating that exploitation is limited to authenticated users with elevated access. The CVSS 4.0 score is 5.1 (medium), reflecting moderate impact on confidentiality, integrity, and availability, with low complexity and no user interaction needed. Although no known exploits are currently active in the wild, the public disclosure of the exploit code increases the risk of future attacks. The vulnerability affects only version 1.0 of the product, and no patches have been publicly linked yet. Organizations using this gym management software should be aware of the risk of unauthorized data manipulation or leakage through this injection flaw.

For European organizations using CodeAstro Gym Management System 1.0, this vulnerability poses a moderate risk. Successful exploitation could lead to unauthorized access or modification of sensitive client data such as membership progress, health metrics, or payment information stored in the database. This could result in data breaches, loss of data integrity, and potential disruption of gym operations. Given the administrative access requirement, the threat is primarily from insider threats or compromised admin accounts. The impact on confidentiality and integrity is medium, while availability impact is low to medium depending on the attacker's actions. Organizations in the fitness and wellness sector, especially those relying on this specific software, may face reputational damage and regulatory scrutiny under GDPR if personal data is exposed or altered. The limited scope to version 1.0 and the need for high privileges reduce the overall risk but do not eliminate it.

1. Immediate mitigation should include restricting administrative access to trusted personnel and enforcing strong authentication mechanisms such as multi-factor authentication (MFA) to reduce the risk of compromised admin accounts. 2. Implement input validation and parameterized queries or prepared statements in the /admin/update-progress.php script to prevent SQL injection. 3. If a patch is released by CodeAstro, apply it promptly. 4. Monitor database logs and application logs for unusual query patterns or unauthorized access attempts targeting the vulnerable parameters. 5. Conduct a thorough audit of user privileges to ensure least privilege principles are enforced. 6. Consider deploying web application firewalls (WAF) with custom rules to detect and block SQL injection attempts targeting the affected endpoint. 7. Educate administrative users about phishing and credential security to prevent account compromise. 8. If immediate patching is not possible, consider isolating the affected system from external networks or limiting network access to trusted IPs only.
