CVE-2025-12242 identifies a SQL injection vulnerability in CodeAstro Gym Management System version 1.0, located in the /admin/actions/check-attendance.php script. The vulnerability arises from improper sanitization of the 'ID' parameter, which is susceptible to malicious SQL payloads. Attackers can remotely exploit this flaw without authentication or user interaction, injecting crafted SQL commands that may allow unauthorized reading, modification, or deletion of database records. The CVSS 4.0 score of 5.3 reflects medium severity, considering the low attack complexity and no privileges required, but limited impact scope and partial confidentiality, integrity, and availability impact. Although no exploits are currently known in the wild, the public disclosure of the vulnerability increases the likelihood of exploitation attempts. The vulnerability affects only version 1.0 of the product, which may limit exposure depending on the deployment footprint. The lack of patches at the time of disclosure necessitates immediate mitigation through secure coding practices and configuration hardening. This vulnerability is particularly critical for organizations relying on this software for attendance tracking and member management, as exploitation could lead to data breaches or operational disruptions.

For European organizations using CodeAstro Gym Management System 1.0, this vulnerability poses risks including unauthorized access to sensitive member data, manipulation of attendance records, and potential disruption of gym operations. Confidentiality could be compromised through data leakage, integrity affected by unauthorized data modification, and availability impacted if the database or application becomes unstable due to injection attacks. Given the remote and unauthenticated nature of the exploit, attackers could leverage this vulnerability to gain foothold within the network or escalate privileges. The medium severity rating suggests moderate risk, but the actual impact depends on the sensitivity of stored data and the criticality of the affected system within organizational workflows. Organizations in the fitness and wellness sector, especially those with regulatory compliance obligations such as GDPR, must consider the legal and reputational consequences of data breaches stemming from this vulnerability.

1. Immediately implement input validation and sanitization for the 'ID' parameter in /admin/actions/check-attendance.php to prevent injection of malicious SQL code. 2. Refactor database queries to use parameterized statements or prepared queries, eliminating direct concatenation of user inputs. 3. Restrict access to the vulnerable endpoint by enforcing strict authentication and authorization controls, even if the vulnerability currently requires no privileges. 4. Monitor application logs for unusual query patterns or repeated failed attempts targeting the 'ID' parameter. 5. Deploy web application firewalls (WAFs) with custom rules to detect and block SQL injection payloads targeting this endpoint. 6. Engage with CodeAstro for official patches or updates and apply them promptly once available. 7. Conduct security code reviews and penetration testing focused on input handling in all administrative modules. 8. Educate development and operations teams about secure coding practices and the risks of SQL injection. 9. Isolate the gym management system network segment to limit lateral movement if compromised. 10. Maintain regular backups of databases to enable recovery in case of data tampering or loss.
