CVE-2026-2059 identifies a SQL injection vulnerability in the SourceCodester Medical Center Portal Management System version 1.0, specifically within the /emp_edit1.php file. The vulnerability arises from improper sanitization of the 'ID' parameter, which allows an attacker to inject malicious SQL code remotely without authentication or user interaction. This can lead to unauthorized data access, modification, or deletion in the backend database. The CVSS 4.0 score of 6.9 reflects a medium severity, considering the ease of exploitation (network accessible, no privileges required), but limited scope of impact due to the specific affected function. The vulnerability compromises confidentiality, integrity, and availability to a limited extent, as the attacker can manipulate employee records or other sensitive data stored in the system. Although no known exploits are active in the wild, the public disclosure increases the risk of exploitation. The lack of patches or vendor advisories necessitates immediate mitigation efforts by users. The vulnerability highlights the critical need for secure coding practices such as parameterized queries and rigorous input validation in healthcare software, where data sensitivity is paramount.

For European organizations, this vulnerability presents a significant risk due to the sensitive nature of medical data handled by the affected portal system. Exploitation could lead to unauthorized disclosure of patient records, alteration of employee or patient information, and potential disruption of healthcare services. Such breaches would violate GDPR requirements, leading to substantial fines and reputational damage. The healthcare sector is a high-value target for cybercriminals, and this vulnerability could be leveraged for further attacks such as ransomware deployment or espionage. The medium severity indicates that while the vulnerability is exploitable remotely without authentication, the impact is somewhat contained to the specific application and database. However, given the criticality of healthcare data, even limited data compromise can have severe consequences for patient privacy and safety. European healthcare providers using this or similar SourceCodester products must consider this vulnerability a priority for remediation to maintain compliance and trust.

1. Immediate code review and remediation of the /emp_edit1.php file to ensure the 'ID' parameter is properly sanitized. 2. Replace dynamic SQL queries with prepared statements or parameterized queries to prevent injection. 3. Implement strict input validation and whitelisting on all user-supplied parameters. 4. Conduct thorough security testing including automated scanning and manual code audits focused on injection flaws. 5. Monitor web application logs for suspicious activity targeting the vulnerable endpoint. 6. Deploy Web Application Firewalls (WAF) with rules to detect and block SQL injection attempts targeting this parameter. 7. If possible, isolate or restrict access to the vulnerable portal until patches or mitigations are applied. 8. Educate development teams on secure coding practices and the importance of input validation. 9. Engage with the vendor or community to obtain or develop official patches or updates. 10. Ensure regular backups and incident response plans are in place to quickly recover from potential exploitation.
