CVE-2025-14939 identifies a SQL injection vulnerability in the code-projects Online Appointment Booking System version 1.0, specifically within the /admin/deletemanager.php script. The vulnerability arises from insufficient input validation or sanitization of the 'managername' parameter, which is used in SQL queries to manage appointment managers. An attacker with authenticated access to the admin interface can manipulate this parameter to inject arbitrary SQL commands, potentially allowing unauthorized reading, modification, or deletion of database records. The attack vector is remote network access, and no user interaction is required beyond authentication, which implies the attacker must have valid admin credentials or exploit other means to gain such access. The CVSS 4.0 vector indicates no user interaction (UI:N), no privileges required (PR:H means high privileges required, so authentication is needed), low complexity (AC:L), and partial impact on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). Although no known exploits are reported in the wild, the public disclosure of exploit code increases the risk of exploitation by malicious actors. The vulnerability could compromise sensitive appointment data, user information, and operational integrity of organizations relying on this system. The absence of patches at the time of publication necessitates immediate mitigation efforts to reduce exposure.

For European organizations, the impact of this vulnerability can be significant, especially for entities relying on the code-projects Online Appointment Booking System for managing appointments in healthcare, government services, or private sectors. Exploitation could lead to unauthorized access to sensitive personal data, including client or patient information, violating GDPR and other data protection regulations. Data integrity could be compromised, resulting in altered or deleted appointment records, potentially disrupting service delivery and causing reputational damage. Availability impacts could arise if attackers manipulate or delete critical database entries, leading to denial of service or operational downtime. The requirement for high privileges limits the attack surface but also means insider threats or compromised admin accounts pose a serious risk. The public availability of exploit code increases the urgency for European organizations to assess their exposure and implement mitigations promptly to avoid regulatory penalties and operational disruptions.

1. Immediately restrict access to the /admin/deletemanager.php functionality to trusted administrators only, using network segmentation and strong authentication mechanisms such as multi-factor authentication (MFA). 2. Implement strict input validation and sanitization on the 'managername' parameter, employing parameterized queries or prepared statements to prevent SQL injection. 3. Monitor database logs and application logs for unusual query patterns or failed login attempts that may indicate exploitation attempts. 4. Conduct a thorough audit of admin accounts to ensure no unauthorized access or credential compromise. 5. If possible, isolate the appointment booking system from public networks or place it behind a web application firewall (WAF) configured to detect and block SQL injection attempts. 6. Engage with the vendor or community to obtain patches or updates addressing this vulnerability and apply them as soon as they become available. 7. Educate administrators on secure credential handling and the risks of privilege escalation to reduce insider threat risks. 8. Regularly back up the database and test restoration procedures to minimize impact in case of data corruption or deletion.
