CVE-2026-11513: SQL Injection in itsourcecode Hospital Management System 1.0

Technical summary

CVE-2026-11513 is a SQL injection flaw (CWE-89, CWE-74) in the Date parameter handler of /adminaccount.php in itsourcecode Hospital Management System 1.0. The application fails to properly sanitize or parameterize user input before incorporating it into SQL queries. This allows authenticated users to inject SQL metacharacters and execute arbitrary database operations. The CVSS v3.1 score of 6.3 (MEDIUM) reflects network accessibility and low-impact data exposure, mitigated by the requirement for prior authentication.

Business impact

Hospital Management Systems are critical infrastructure handling patient records, billing, scheduling, and care coordination. A successful SQL injection could result in unauthorized access to protected health information (PHI), regulatory violations (HIPAA), operational disruption, data tampering, or patient safety incidents if clinical records are altered. The requirement for authentication limits immediate mass exploitation but insider threats and compromised credentials remain viable attack vectors. Reputational and legal liability may be substantial for healthcare organizations.

Affected systems

itsourcecode Hospital Management System version 1.0 is confirmed vulnerable. No indication of later versions being affected; however, verify with the vendor whether 1.0 is still in active support and whether successor versions have addressed this issue. Deployments in healthcare facilities, clinics, or hospital networks running this specific version require immediate assessment.

Exploitability

The vulnerability has a low complexity attack surface (CVSS AC:L) and is remotely exploitable without user interaction (UI:N). However, it requires valid authentication credentials (PR:L), which prevents wormable propagation but aligns with typical hospital network access controls where staff obtain accounts. Public exploit code availability increases practical exploitation risk. Threat actors with stolen or social-engineered credentials can weaponize this quickly.

Remediation

Prioritize vendor contact to confirm available patches or end-of-life status for version 1.0. If patches exist, deploy them to all affected instances after testing in a non-production environment. If no patches are forthcoming, consider migrating to a supported Hospital Management System. Interim mitigations include: restricting network access to /adminaccount.php via firewall rules, implementing Web Application Firewall (WAF) rules to detect SQL injection patterns in the Date parameter, enforcing strong credential hygiene, and conducting network segmentation to isolate the application.

Patch guidance

Contact itsourcecode directly for patch availability and timelines. Verify patch version numbers against official vendor advisories before deployment. Test thoroughly in a staging hospital environment to ensure clinical workflows and integrations remain unaffected. Consider coordinating updates with your hospital IT governance and change management processes, particularly if the system is in active patient care use. Document all patching activities for compliance audits.

Detection guidance

Monitor /adminaccount.php access logs for unusual Date parameter values containing SQL keywords (SELECT, UNION, OR, AND, DROP, etc.) and special characters (single quotes, semicolons, hyphens). Enable database query logging to detect anomalous SQL execution patterns. Implement intrusion detection signatures targeting SQL injection payloads. Alert on failed database queries originating from the application. Review authentication logs for credential abuse or unusual login patterns preceding the injection attempts. Network traffic analysis can identify data exfiltration following successful injection.

Why prioritize this

Although not yet listed on CISA's Known Exploited Vulnerabilities catalog, the combination of public exploits, healthcare sector criticality, PHI exposure risk, and authentication requirement warrants immediate attention. This is not a critical zero-day but a readily exploitable flaw in infrastructure handling sensitive data. Organizations should treat this as a high-priority patch candidate given regulatory compliance obligations and reputational consequences.

Risk score, explained

The CVSS v3.1 MEDIUM score (6.3) appropriately reflects the dual nature of this flaw: network accessibility and broad potential impact (confidentiality, integrity, availability) are offset by the requirement for prior authentication. For healthcare organizations, the risk is contextually higher due to the sensitivity of hospital data and regulatory mandates; internal risk assessment should weigh business criticality, patient safety implications, and regulatory exposure beyond the base CVSS metric.
