CVE-2025-12242 is a SQL injection vulnerability identified in CodeAstro Gym Management System version 1.0. The vulnerability exists in an unspecified functionality within the /admin/actions/check-attendance.php script, where the 'ID' parameter is improperly sanitized, allowing an attacker to inject malicious SQL commands. This injection flaw can be exploited remotely without requiring user interaction or prior authentication, enabling attackers to manipulate backend database queries. The vulnerability can lead to unauthorized data access, modification, or deletion, impacting the confidentiality, integrity, and availability of the system's data. The CVSS 4.0 vector indicates low complexity (AC:L), no privileges required (PR:L), no user interaction (UI:N), and partial impact on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). Although no public exploits are currently known in the wild, the public disclosure of the vulnerability increases the risk of exploitation by threat actors. The affected product is used for managing gym operations, including attendance tracking, which may contain sensitive personal and operational data. The lack of available patches or official mitigation guidance necessitates immediate defensive measures by users of the affected version.

For European organizations using CodeAstro Gym Management System 1.0, this vulnerability poses a risk of unauthorized database access and manipulation. Attackers could extract sensitive personal data of gym members, including attendance records and possibly payment or health-related information, leading to privacy violations under GDPR. Integrity of attendance data could be compromised, affecting operational decisions and reporting. Availability could be impacted if attackers execute destructive SQL commands, potentially disrupting gym management services. The remote and unauthenticated nature of the exploit increases the attack surface, especially for gyms with externally accessible management portals. This could lead to reputational damage, regulatory penalties, and financial losses. Organizations in Europe with a high reliance on this software for daily operations are particularly vulnerable, especially those lacking robust network segmentation or monitoring.

1. Immediately implement input validation and sanitization on the 'ID' parameter in /admin/actions/check-attendance.php to prevent SQL injection. 2. Employ parameterized queries or prepared statements in the application code to eliminate direct concatenation of user input into SQL commands. 3. Restrict external access to the admin interface through network controls such as VPNs, IP whitelisting, or firewall rules to limit exposure. 4. Monitor database logs and application logs for unusual queries or access patterns indicative of exploitation attempts. 5. Conduct a thorough code review of the entire application to identify and remediate similar injection flaws. 6. If possible, isolate the gym management system in a segmented network zone to reduce lateral movement risks. 7. Engage with the vendor for official patches or updates and apply them promptly once available. 8. Educate administrative users on security best practices and ensure strong authentication mechanisms are in place to reduce privilege misuse.
