CVE-2025-67146 identifies multiple SQL Injection vulnerabilities in the AbhishekMali21 GYM-MANAGEMENT-SYSTEM version 1.0. The vulnerabilities are located in four PHP scripts: member_search.php, trainer_search.php, gym_search.php (all via the 'name' parameter), and payment_search.php (via the 'id' parameter). SQL Injection occurs when user-supplied input is improperly sanitized and directly included in SQL queries, allowing attackers to manipulate the database queries executed by the application. In this case, an unauthenticated remote attacker can craft malicious input to these parameters to execute arbitrary SQL commands. Potential consequences include unauthorized extraction of sensitive data such as member details and payment information, bypassing authentication mechanisms to gain unauthorized access, and modifying or deleting database records, which can disrupt business operations. The absence of authentication requirements and user interaction makes exploitation straightforward if the vulnerable endpoints are exposed. Although no CVSS score is assigned, the vulnerabilities are critical due to their impact and ease of exploitation. No patches or mitigations are currently linked, and no known exploits have been reported in the wild as of the publication date. Organizations using this gym management system or similar vulnerable software should consider these risks seriously.

For European organizations, the impact of CVE-2025-67146 can be severe. Fitness centers and gyms often store personal data of members, including names, contact information, health details, and payment records. Exploitation could lead to unauthorized disclosure of personally identifiable information (PII), violating GDPR and other data protection regulations, resulting in legal penalties and reputational damage. Authentication bypass could allow attackers to assume administrative roles, leading to further compromise of internal systems. Modification or deletion of data could disrupt business continuity and trust. Since the vulnerability requires no authentication and no user interaction, attackers can remotely exploit it if the application is internet-facing or insufficiently protected by network controls. The lack of patches increases the risk window. Organizations may also face indirect impacts such as loss of customer trust and financial losses due to fraud or remediation costs.

European organizations should immediately audit their use of the GYM-MANAGEMENT-SYSTEM 1.0 or any similar software for these vulnerabilities. Specific mitigations include: 1) Implement input validation and parameterized queries (prepared statements) to prevent SQL Injection, ensuring all user inputs are sanitized and never directly concatenated into SQL commands. 2) Restrict access to vulnerable endpoints by network segmentation or firewall rules to limit exposure to untrusted networks. 3) Employ Web Application Firewalls (WAFs) with SQL Injection detection and blocking capabilities to provide an additional layer of defense. 4) Conduct code reviews and security testing (e.g., dynamic application security testing) to identify and remediate injection flaws. 5) Monitor logs for suspicious query patterns indicative of injection attempts. 6) If possible, replace or upgrade the vulnerable software to a patched or more secure alternative. 7) Educate developers and administrators on secure coding practices and the risks of SQL Injection. 8) Prepare incident response plans to quickly address any exploitation attempts. These steps go beyond generic advice by focusing on immediate containment, code-level fixes, and proactive monitoring tailored to this specific vulnerability.
