CVE-2025-12261 is an SQL injection vulnerability identified in CodeAstro Gym Management System version 1.0. The vulnerability exists in the /admin/actions/remove-announcement.php file, where the ID parameter is improperly sanitized, allowing an attacker to inject malicious SQL code. This injection flaw can be exploited remotely without user interaction but requires low-level privileges (PR:L), indicating that some form of authentication or limited privilege is necessary. The vulnerability impacts the confidentiality, integrity, and availability of the system’s backend database by enabling unauthorized data retrieval, modification, or deletion. The CVSS 4.0 base score is 5.3 (medium), reflecting the moderate risk due to the requirement of privileges and limited scope of impact. The attack complexity is low, and no user interaction is needed, increasing the likelihood of exploitation once credentials or access are obtained. Although no known exploits in the wild have been reported, the public disclosure of the exploit code increases the risk of future attacks. The vulnerability is critical for organizations relying on this gym management software, as it could lead to data breaches, unauthorized administrative actions, or disruption of service. The absence of vendor patches at the time of disclosure necessitates immediate defensive measures to mitigate risk.

The SQL injection vulnerability could allow attackers with limited privileges to execute arbitrary SQL commands on the backend database, potentially leading to unauthorized disclosure of sensitive information such as user data, membership details, and financial records. Attackers might also alter or delete data, impacting data integrity and disrupting gym management operations. The availability of the system could be affected if attackers execute commands that cause database errors or crashes. For organizations, this could result in reputational damage, regulatory penalties due to data breaches, and operational downtime. Since the vulnerability requires some level of privilege, the impact is somewhat contained but still significant, especially if privilege escalation or credential compromise occurs. The public availability of exploit code increases the risk of automated attacks targeting vulnerable installations worldwide.

1. Immediately restrict access to the /admin/actions/remove-announcement.php endpoint to trusted administrators only, ideally via network segmentation or VPN. 2. Implement strict input validation and sanitization on all parameters, especially the ID parameter, using allowlists and rejecting unexpected input formats. 3. Employ parameterized queries or prepared statements in the application code to prevent SQL injection. 4. Monitor logs for suspicious database queries or repeated access attempts to the vulnerable endpoint. 5. Enforce strong authentication and access control policies to minimize the risk of privilege abuse. 6. Regularly audit and update the CodeAstro Gym Management System software, applying vendor patches promptly once available. 7. Consider deploying Web Application Firewalls (WAFs) with rules to detect and block SQL injection attempts targeting this endpoint. 8. Conduct security training for administrators to recognize and report suspicious activities. 9. Backup databases regularly to enable recovery in case of data tampering or loss.
