CVE-2026-2057 is a SQL Injection vulnerability identified in the SourceCodester Medical Center Portal Management System version 1.0. The vulnerability resides in the /login.php file, where the User parameter is improperly sanitized, allowing an attacker to inject arbitrary SQL commands. This injection flaw can be exploited remotely without requiring authentication or user interaction, making it accessible to a wide range of attackers. The vulnerability can lead to unauthorized access to the backend database, enabling attackers to read, modify, or delete sensitive patient data or administrative information. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and partial impacts on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). Although no official patches or fixes have been released yet, public exploit code is available, increasing the likelihood of exploitation. The vulnerability affects only version 1.0 of the product, which is a specialized medical portal management system used primarily in healthcare environments. The lack of segmentation or additional security controls in the affected function exacerbates the risk of data compromise. This vulnerability highlights the critical need for secure coding practices and timely patching in healthcare software to protect sensitive medical information.

The exploitation of this SQL Injection vulnerability can have severe consequences for healthcare organizations using the affected software. Attackers can gain unauthorized access to sensitive patient records, including personal health information (PHI), which can lead to privacy violations and regulatory non-compliance (e.g., HIPAA in the US, GDPR in Europe). Data integrity may be compromised if attackers modify or delete records, potentially impacting patient care and trust. Availability of the portal could also be disrupted, affecting healthcare operations and access to critical services. The remote and unauthenticated nature of the exploit increases the attack surface, enabling widespread exploitation attempts. Organizations may face reputational damage, legal liabilities, and financial losses due to data breaches. Given the specialized nature of the software, organizations relying on this system without alternative solutions may experience operational disruptions until mitigations or patches are applied.

1. Implement immediate input validation and sanitization on the User parameter in /login.php to prevent SQL injection attempts. 2. Deploy a web application firewall (WAF) with rules specifically designed to detect and block SQL injection payloads targeting the affected endpoint. 3. Conduct a thorough code review of the application to identify and remediate other potential injection points. 4. Restrict database user permissions to the minimum necessary to limit the impact of a successful injection attack. 5. Monitor application logs and network traffic for unusual queries or access patterns indicative of exploitation attempts. 6. Isolate the affected system within the network to reduce exposure and prevent lateral movement. 7. Engage with the vendor or community to obtain or develop patches or updates addressing this vulnerability. 8. Educate IT and security teams on the risks and detection methods related to SQL injection attacks in healthcare environments. 9. Consider temporary alternative authentication mechanisms or multi-factor authentication to reduce risk while remediation is underway.
