CVE-2025-11319 identifies an SQL injection vulnerability in the nahiduddinahammed Hospital-Management-System-Website, specifically in the /delete.php script where the 'ai' parameter is improperly sanitized. This flaw allows an unauthenticated remote attacker to inject malicious SQL commands, potentially leading to unauthorized data access, modification, or deletion within the backend database. The vulnerability is exploitable over the network without user interaction, increasing its risk profile. The product follows a rolling release model, complicating patch management as no fixed version numbers or official patches are available. The vendor has not responded to early disclosure attempts, leaving users without official remediation guidance. Although no active exploitation has been reported, public availability of exploit code raises the likelihood of attacks. The vulnerability impacts confidentiality by exposing sensitive patient and hospital data, integrity by allowing unauthorized data manipulation, and availability by potentially disrupting hospital management operations. The CVSS 4.0 score of 5.3 reflects medium severity, considering the lack of authentication but limited scope and complexity of exploitation. The absence of CWE identifiers suggests incomplete vulnerability classification, but the nature of SQL injection is well understood and critical in healthcare contexts. This threat requires urgent attention due to the sensitive nature of healthcare data and the operational importance of hospital management systems.

For European organizations, this vulnerability poses significant risks to patient privacy, regulatory compliance (e.g., GDPR), and operational continuity. Exploitation could lead to unauthorized disclosure of personal health information, violating data protection laws and resulting in legal penalties and reputational damage. Integrity attacks could corrupt patient records or hospital scheduling data, potentially endangering patient safety. Availability impacts could disrupt hospital workflows, delaying critical care services. Given the healthcare sector's critical infrastructure status in Europe, such disruptions could have cascading effects on public health. Additionally, the public availability of exploit code increases the risk of opportunistic attacks by cybercriminals or hacktivists targeting European healthcare providers. The lack of vendor response and patch availability complicates mitigation efforts, increasing exposure duration. Organizations relying on this system or similar open-source hospital management platforms must consider this vulnerability a priority for risk management and incident preparedness.

1. Conduct immediate code audits focusing on the /delete.php endpoint to identify and sanitize all user inputs, especially the 'ai' parameter, using parameterized queries or prepared statements to prevent SQL injection. 2. Deploy Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting this endpoint. 3. Implement network segmentation to isolate the hospital management system and its database from broader enterprise networks, limiting lateral movement if compromised. 4. Monitor logs for suspicious database queries or unusual activity related to the /delete.php script. 5. Engage with cybersecurity vendors or open-source communities to seek or develop patches or mitigation scripts given the vendor's lack of response. 6. Educate IT and security teams about the vulnerability and ensure incident response plans include scenarios involving SQL injection attacks on critical healthcare systems. 7. Consider deploying database activity monitoring tools to detect and alert on anomalous SQL commands. 8. If feasible, replace or upgrade the affected system with a more secure alternative that follows secure coding practices and provides timely vendor support.
