CVE-2026-10208: SQL Injection in Online Hospital Management System Login

Technical summary

The vulnerability stems from insufficient input validation on the Username parameter passed to the login_user function. The application fails to properly sanitize or parameterize SQL queries, allowing attackers to craft malicious payloads that alter query logic. CWE-89 (SQL Injection) and CWE-74 (Improper Neutralization of Special Elements) are both applicable. An unauthenticated remote attacker can execute arbitrary SQL commands with the privileges of the application's database user, potentially reading, modifying, or deleting sensitive data. The CVSS 3.1 score of 7.3 reflects the high severity due to network accessibility, low attack complexity, and impact to confidentiality, integrity, and availability.

Business impact

Hospital management systems store protected health information (PHI), patient records, appointment data, and billing information. Successful exploitation could expose sensitive patient data, disrupt service availability, modify treatment records, or compromise system integrity. Organizations face regulatory violations under HIPAA and other healthcare compliance frameworks, potential legal liability, reputational damage, and operational disruption. An attacker could also use the system as a pivot point for lateral movement within the healthcare network.

Affected systems

The vulnerability affects code-projects Online Hospital Management System version 1.php. Organizations running this application should immediately inventory affected deployments. Verify the specific version number against vendor advisories to confirm exposure, as patch availability and scope may vary.

Exploitability

The attack requires only network access and no prior authentication or user interaction. Exploitation is straightforward—an attacker submits a crafted SQL payload in the Username field at the login page. Public exploit code is already available, lowering the barrier to attack. Given the simplicity and the remote, unauthenticated nature of exploitation, expect active abuse and opportunistic scanning.

Remediation

Immediate remediation is essential. First, patch the application if a vendor update is available—verify current patch status with the code-projects vendor. If patching is delayed, implement compensating controls: apply Web Application Firewall (WAF) rules to block SQL injection patterns in login requests, enforce strict input validation and parameterized queries, limit database account privileges to least-privilege principles, and enable detailed query logging for forensic analysis. Monitor for suspicious login attempts and successful database access anomalies.

Patch guidance

Contact the code-projects vendor or check their advisory repository for available patches. Apply patches during a maintenance window with database backups and rollback procedures in place. Test thoroughly in a non-production environment before production deployment. If no patch is available, implement WAF-based protections and request an estimated release timeline from the vendor.

Detection guidance

Monitor login_1.php for requests containing SQL keywords in the Username parameter (e.g., UNION, SELECT, DROP, OR '1'='1). Enable SQL query logging at the database layer to detect unusual command patterns. Check authentication logs for failed logins followed by successful access without corresponding user sessions. Hunt for POST requests to the login endpoint with abnormally long or encoded payloads. Endpoint detection and response (EDR) tools should flag processes spawned from the application with unexpected privileges.

Why prioritize this

This is a high-priority vulnerability requiring immediate action. SQL injection in a login function directly undermines authentication controls and exposes the entire system. Healthcare data sensitivity, regulatory compliance requirements, active exploitation, and public availability of proof-of-concept code all demand urgent remediation. Organizations without a patch must implement emergency compensating controls.

Risk score, explained

The CVSS 3.1 score of 7.3 (HIGH) reflects: (1) Network-based attack vector requiring no special network position; (2) Low attack complexity—no specialized skills needed; (3) No authentication or user interaction required; (4) Impact to all three security pillars (confidentiality, integrity, availability). The score does not account for the published exploit or healthcare-specific regulatory context, which elevate practical organizational risk beyond the base score.
