CVE-2025-64081 identifies a critical SQL injection vulnerability in the SourceCodester Patients Waiting Area Queue Management System version 1. The vulnerability resides in the /php/api_patient_schedule.php script, where the appointmentID parameter is not properly sanitized or validated, allowing attackers to inject arbitrary SQL commands. This can lead to unauthorized data access, modification, or deletion within the backend database. SQL injection attacks exploit improper input handling, enabling attackers to manipulate queries executed by the database server. In this case, the appointmentID parameter likely interacts with patient scheduling data, making the impact particularly sensitive due to the nature of healthcare information. Although no CVSS score or known exploits are currently documented, the vulnerability's presence in a healthcare queue management system raises significant concerns about patient data confidentiality and operational integrity. The lack of patches or fixes at this time means organizations must rely on immediate mitigations such as input validation and query parameterization. The vulnerability does not require authentication or user interaction, increasing its risk profile. Given the criticality of healthcare systems and the potential for widespread impact, this vulnerability demands urgent attention from security teams managing affected deployments.

The impact of CVE-2025-64081 on European organizations, particularly those in the healthcare sector, can be severe. Exploitation could lead to unauthorized disclosure of sensitive patient information, violating GDPR and other data protection regulations, resulting in legal and financial penalties. Attackers could also alter or delete appointment data, disrupting patient care and operational workflows, potentially endangering patient safety. The availability of the queue management system could be compromised, causing delays and inefficiencies in healthcare service delivery. Additionally, successful exploitation might serve as a foothold for further network intrusion or lateral movement within healthcare IT environments. European healthcare providers, hospitals, and clinics using SourceCodester or similar vulnerable queue management systems are at risk of reputational damage and loss of patient trust. The absence of known exploits in the wild currently limits immediate widespread impact, but the vulnerability's nature and context suggest a high potential for targeted attacks, especially in countries with advanced healthcare infrastructure and digital patient management systems.

To mitigate CVE-2025-64081, organizations should immediately implement strict input validation and sanitization on the appointmentID parameter to prevent malicious SQL code injection. Employ parameterized queries or prepared statements in the backend code to ensure that user input is treated as data rather than executable code. Conduct thorough code reviews and security testing of the /php/api_patient_schedule.php endpoint and related components. Restrict database user permissions to the minimum necessary to limit the impact of potential exploitation. Monitor database logs and application behavior for unusual query patterns or failed injection attempts. If possible, isolate the queue management system within a segmented network zone to reduce lateral movement risks. Stay alert for official patches or updates from SourceCodester and apply them promptly once available. Additionally, implement web application firewalls (WAFs) with SQL injection detection rules tailored to the affected endpoint. Educate development and IT teams on secure coding practices to prevent similar vulnerabilities in future releases.
