CVE-2025-14833 is a SQL injection vulnerability identified in the code-projects Online Appointment Booking System version 1.0, specifically within the /admin/deletemanagerclinic.php file. The vulnerability arises from improper sanitization of the 'clinic' parameter, which is passed to an unknown function that interacts with the database. An attacker can remotely exploit this flaw without any authentication or user interaction by manipulating the 'clinic' argument to inject malicious SQL statements. This can lead to unauthorized data access, modification, or deletion within the backend database, potentially compromising sensitive appointment and user information. The vulnerability has a CVSS 4.0 base score of 6.9, indicating medium severity, with attack vector network (remote), low attack complexity, and no privileges or user interaction required. The impact on confidentiality, integrity, and availability is limited but present. Although no known exploits are currently active in the wild, the public release of exploit code increases the likelihood of exploitation attempts. The affected product is used primarily in healthcare and service industries for managing appointments, making the vulnerability relevant for organizations relying on this software for operational continuity and data security. No official patches have been released yet, necessitating immediate mitigation efforts by users of the affected version.

For European organizations, the impact of this vulnerability can be significant, especially for healthcare providers, clinics, and service businesses that rely on the code-projects Online Appointment Booking System for managing appointments. Exploitation could lead to unauthorized access to sensitive patient or client data, manipulation or deletion of appointment records, and potential disruption of service availability. This could result in privacy violations under GDPR, reputational damage, operational downtime, and financial penalties. The remote and unauthenticated nature of the attack vector increases the risk, as attackers can exploit the flaw without needing internal access or user credentials. While the vulnerability's impact is medium, the exposure of sensitive healthcare data and disruption to critical appointment scheduling services could have cascading effects on patient care and organizational trust. European organizations with limited security monitoring or outdated software management practices are particularly vulnerable.

1. Immediate code review and remediation: Sanitize and validate all inputs to the 'clinic' parameter in /admin/deletemanagerclinic.php to prevent SQL injection. Use parameterized queries or prepared statements. 2. Restrict access: Limit access to the /admin/deletemanagerclinic.php endpoint to trusted IP addresses or via VPN to reduce exposure. 3. Monitor logs: Implement enhanced logging and monitoring for unusual database queries or failed injection attempts targeting the vulnerable parameter. 4. Network segmentation: Isolate the appointment booking system from other critical infrastructure to contain potential breaches. 5. Incident response readiness: Prepare to respond to potential exploitation attempts by having backups and recovery plans in place. 6. Vendor engagement: Contact the software vendor for official patches or updates and apply them promptly once available. 7. Web Application Firewall (WAF): Deploy or update WAF rules to detect and block SQL injection attempts targeting this endpoint. 8. Security awareness: Educate administrators about the vulnerability and the importance of not exposing administrative interfaces publicly.
