CVE-2025-56214 is a SQL Injection vulnerability identified in the phpgurukul Hospital Management System version 4.0, specifically within the index.php file via the 'username' parameter. SQL Injection (SQLi) vulnerabilities occur when untrusted user input is improperly sanitized and directly incorporated into SQL queries, allowing an attacker to manipulate the database query logic. In this case, the 'username' parameter is vulnerable, meaning an attacker can craft malicious input to execute arbitrary SQL commands against the backend database. This could lead to unauthorized data access, data modification, or even complete compromise of the database server. Since this vulnerability exists in a hospital management system, the sensitive nature of the data involved—such as patient records, medical histories, and administrative information—raises significant confidentiality and integrity concerns. The vulnerability is reported without a CVSS score and no known exploits in the wild have been documented yet. However, SQL Injection remains one of the most critical and commonly exploited vulnerabilities due to its potential impact and relative ease of exploitation. The absence of a patch link suggests that either a fix has not yet been released or is not publicly available at this time. The vulnerability was published on August 25, 2025, with the reservation date on August 16, 2025, indicating recent discovery and disclosure. The lack of affected version details beyond version 4.0 limits precise scope assessment, but it is reasonable to assume that all installations running this version are at risk. No additional technical details or CWEs are provided, but the core issue is clear: improper input validation leading to SQL Injection via the username parameter in a critical healthcare application.

For European organizations, particularly healthcare providers using the phpgurukul Hospital Management System 4.0, this vulnerability poses a severe risk to patient data confidentiality, integrity, and availability. Exploitation could allow attackers to extract sensitive personal health information (PHI), violating GDPR regulations and potentially resulting in heavy fines and reputational damage. Unauthorized modification of medical records could lead to incorrect treatment decisions, endangering patient safety. Additionally, attackers might leverage the vulnerability to escalate privileges within the hospital's IT infrastructure or deploy ransomware, disrupting critical healthcare services. The impact extends beyond individual hospitals to interconnected healthcare networks and insurance providers, amplifying the risk. Given the critical nature of healthcare services and strict regulatory environment in Europe, this vulnerability demands urgent attention to prevent data breaches and service interruptions.

Immediate mitigation should focus on input validation and sanitization of the 'username' parameter in index.php to prevent malicious SQL code execution. Implement parameterized queries or prepared statements to ensure user input is treated as data, not executable code. Conduct a comprehensive code review of the Hospital Management System to identify and remediate other potential injection points. If a patch becomes available from the vendor, prioritize its deployment after testing in a controlled environment. In the interim, consider deploying Web Application Firewalls (WAFs) with rules specifically designed to detect and block SQL Injection attempts targeting the affected parameter. Regularly monitor logs for suspicious query patterns or repeated failed login attempts that may indicate exploitation attempts. Educate IT and security teams on the risks and signs of SQL Injection attacks. Finally, ensure that database accounts used by the application have the minimum necessary privileges to limit the impact of any successful exploitation.
