CVE-2025-11589 identifies a SQL injection vulnerability in CodeAstro Gym Management System version 1.0, located in the /admin/user-payment.php file. The vulnerability stems from insufficient input validation or sanitization of the 'plan' parameter, which is used in SQL queries without proper escaping or parameterization. This allows an attacker with low privileges to remotely inject malicious SQL code, potentially manipulating the database to extract sensitive information, modify records, or disrupt service availability. The attack vector is network accessible (AV:N), requires low complexity (AC:L), no authentication (AT:N), and no user interaction (UI:N), but low privileges (PR:L) are needed, indicating that an attacker must have some level of access, such as a low-privileged admin or authenticated user. The impact on confidentiality, integrity, and availability is limited but present (VC:L, VI:L, VA:L). The vulnerability has a CVSS 4.0 base score of 5.3, categorized as medium severity. Although no known active exploits have been reported, a public exploit is available, increasing the likelihood of exploitation. No official patches or fixes have been released by the vendor, leaving systems exposed. This vulnerability is critical for organizations relying on this gym management software to protect customer payment and membership data. Attackers could leverage this flaw to compromise financial records or user information, leading to reputational damage and regulatory consequences.

The SQL injection vulnerability can lead to unauthorized disclosure of sensitive data such as payment details and user information, undermining confidentiality. Attackers might alter or delete database records, affecting data integrity and potentially disrupting gym operations or billing processes. Availability could be impacted if attackers execute destructive queries or cause database errors. Organizations worldwide using CodeAstro Gym Management System 1.0 face risks of data breaches, financial fraud, and operational downtime. The presence of a public exploit increases the risk of automated or targeted attacks. Compromise could result in regulatory penalties, loss of customer trust, and financial losses. The requirement for low privileges limits the attack surface but does not eliminate risk, especially if low-privileged accounts are compromised or if insider threats exist. The medium severity rating reflects the moderate but tangible risk posed by this vulnerability.

Organizations should immediately audit their use of CodeAstro Gym Management System 1.0 and restrict access to the /admin/user-payment.php functionality to trusted personnel only. Implement web application firewall (WAF) rules to detect and block SQL injection patterns targeting the 'plan' parameter. Employ strict input validation and parameterized queries or prepared statements in the application code to prevent injection. Monitor logs for suspicious database queries or unusual admin activity. If possible, isolate the affected system from external networks or restrict network access to trusted IPs. Engage with the vendor for patches or updates and apply them promptly once available. Conduct regular security assessments and penetration testing focused on SQL injection vectors. Educate administrators about the risks of low-privileged account compromise and enforce strong authentication and access controls. Consider database-level protections such as least privilege for database users and query anomaly detection. Maintain backups to enable recovery in case of data tampering or loss.
