CVE-2026-2057 is a SQL Injection vulnerability identified in version 1.0 of the SourceCodester Medical Center Portal Management System, specifically within the /login.php script. The vulnerability arises from improper sanitization of the User parameter, which allows an attacker to inject arbitrary SQL code remotely without requiring authentication or user interaction. This injection flaw can be exploited to manipulate backend database queries, potentially enabling attackers to bypass authentication, extract sensitive patient and administrative data, modify records, or disrupt system availability. The vulnerability has a CVSS 4.0 base score of 6.9, indicating a medium severity level, with attack vector being network-based and no privileges or user interaction needed. The exploit code is publicly available, increasing the likelihood of exploitation despite no confirmed active attacks reported. The affected product is used in medical center portals, which typically handle sensitive health information, making the impact of a successful attack significant. The lack of vendor patches or official remediation guidance necessitates immediate defensive measures by users of this software. This vulnerability exemplifies the critical need for secure coding practices such as input validation and parameterized queries in healthcare applications.

For European organizations, particularly those in the healthcare sector using the SourceCodester Medical Center Portal Management System 1.0, this vulnerability poses a significant risk to patient data confidentiality and system integrity. Successful exploitation could lead to unauthorized access to sensitive medical records, potentially violating GDPR and other data protection regulations, resulting in legal and financial penalties. Data manipulation or deletion could disrupt healthcare services, impacting patient care and operational continuity. The remote, unauthenticated nature of the exploit increases the attack surface, making it easier for threat actors to target healthcare providers. Additionally, public availability of exploit code raises the risk of opportunistic attacks. The reputational damage from a breach could be severe, undermining patient trust. Given the critical nature of healthcare services, any downtime or data compromise could have life-threatening consequences. Therefore, the impact extends beyond IT concerns to patient safety and regulatory compliance.

Organizations should immediately implement input validation and sanitization on the User parameter in /login.php to prevent SQL injection. Employing parameterized queries or prepared statements is essential to eliminate direct injection risks. If source code modification is not feasible, deploying Web Application Firewalls (WAFs) with specific SQL injection detection and blocking rules can provide interim protection. Monitoring login attempts and database query logs for anomalous patterns may help detect exploitation attempts early. Organizations should also conduct thorough security assessments of their medical portal systems to identify similar vulnerabilities. Given the lack of official patches, consider isolating or segmenting the affected system within the network to limit exposure. Regular backups of critical data should be maintained to enable recovery in case of data tampering. Finally, healthcare providers should stay informed about updates from the vendor or security community for any forthcoming patches or advisories.
