CVE-2025-56216 identifies a SQL Injection vulnerability in the phpgurukul Hospital Management System version 4.0, specifically within the about-us.php page via the 'pagetitle' parameter. SQL Injection (SQLi) is a critical web application vulnerability that allows an attacker to manipulate backend SQL queries by injecting malicious input. In this case, the 'pagetitle' parameter is not properly sanitized or validated, enabling an attacker to craft input that alters the intended SQL query logic. This can lead to unauthorized data access, data modification, or even full compromise of the underlying database. Hospital Management Systems (HMS) typically store sensitive patient data, appointment schedules, billing information, and other critical healthcare records. Exploiting this vulnerability could allow attackers to extract confidential patient information, modify records, or disrupt hospital operations. Although no known exploits are reported in the wild yet, the vulnerability is publicly disclosed and unpatched, increasing the risk of future exploitation. The absence of a CVSS score suggests that the vulnerability has not yet been fully assessed, but the nature of SQL Injection in a healthcare context is inherently high risk. The lack of available patches or mitigations in the provided data indicates that organizations using this HMS version remain exposed until a fix is released and applied.

For European organizations, particularly hospitals and healthcare providers using phpgurukul Hospital Management System 4.0, this vulnerability poses a significant threat to patient confidentiality, data integrity, and system availability. Unauthorized access to patient records could lead to privacy violations under GDPR, resulting in legal penalties and reputational damage. Data tampering could affect clinical decisions, potentially endangering patient safety. Additionally, attackers could disrupt hospital operations by corrupting data or causing system outages, impacting critical healthcare delivery. The healthcare sector in Europe is a frequent target for cyberattacks due to the value of medical data and the critical nature of services, making this vulnerability especially concerning. Even though no active exploitation is reported, the public disclosure increases the likelihood of attackers developing exploits, thus elevating the risk for European healthcare entities.

Organizations should immediately audit their use of phpgurukul Hospital Management System 4.0 and identify any deployments of the affected version. Since no official patches are currently available, temporary mitigations include implementing Web Application Firewalls (WAFs) with specific rules to detect and block SQL Injection attempts targeting the 'pagetitle' parameter. Input validation and sanitization should be enforced at the application level, ensuring that user-supplied data is properly escaped or parameterized before database queries. If possible, restrict database user permissions to the minimum necessary to limit the impact of a successful injection. Monitoring and logging of web application traffic should be enhanced to detect suspicious activities. Organizations should also engage with the vendor or community to obtain patches or updates and plan for prompt deployment once available. Conducting security assessments and penetration testing focused on SQL Injection vulnerabilities in the HMS environment is recommended to identify and remediate similar issues proactively.
