CVE-2026-13542: SQL Injection in itsourcecode Hospital Management System 1.0

Technical summary

CVE-2026-13542 is a SQL injection vulnerability (CWE-89, CWE-74) in itsourcecode Hospital Management System 1.0 affecting the /doctorprofile.php endpoint. The doctorname parameter is inadequately sanitized, allowing an authenticated user to inject malicious SQL. The CVSS 3.1 score of 6.3 reflects network accessibility, low attack complexity, and requirement for prior authentication, balanced against confidentiality, integrity, and availability impact limited to the application context. No input validation or parameterized query mechanism appears to be in place for this parameter.

Business impact

Hospital Management Systems hold protected health information (PHI) and operational continuity is critical. A successful SQL injection could expose patient records, modify treatment histories, corrupt appointment schedules, or disrupt clinician access to vital information. For organizations running version 1.0, the combination of authenticated access and data manipulation capability creates material risk to HIPAA compliance, patient safety assurance, and organizational reputation. Downtime or data recovery costs could be substantial.

Affected systems

itsourcecode Hospital Management System version 1.0 is affected. The vendor did not provide product family or version range data, so assume only version 1.0 is confirmed vulnerable. Organizations should verify if they operate this specific product and version, and check with itsourcecode for whether newer versions address this flaw or remain vulnerable.

Exploitability

Exploitation requires valid authentication credentials—this is not an unauthenticated remote code execution. However, the CVSS vector indicates low attack complexity, suggesting the injection is straightforward once a user is logged in. Public disclosure has occurred, increasing the likelihood that exploit code or payloads are circulating. Internal threats (disgruntled staff, compromised credentials) or lateral movement from adjacent breaches become the primary attack path. Healthcare environments with weak credential management face elevated risk.

Remediation

Immediate action: contact itsourcecode to obtain a patched version or security update for Hospital Management System. If an update is not available, implement input validation and parameterized SQL queries (prepared statements) for the doctorname parameter as a temporary control. Monitor database logs for suspicious SQL syntax in doctor profile queries. Restrict access to /doctorprofile.php to authorized clinical and administrative roles. Long-term: migrate to a supported, actively maintained Hospital Management System with secure coding practices.

Patch guidance

Check the itsourcecode website and security advisories for version 1.0.1 or later. Vendors often do not publicly disclose patch versions until advisory release; verify against the official itsourcecode security page or contact their support team directly. Apply updates in a test environment first to ensure compatibility with existing patient data and workflows. For healthcare systems, coordinate patching with your change control board and schedule updates during low-traffic windows to minimize disruption.

Detection guidance

Enable SQL error logging and query monitoring on your database backend. Look for doctorname parameter values containing SQL syntax (UNION, SELECT, OR 1=1, comment characters, etc.). Monitor authentication logs for repeated failed or unusual doctor profile access patterns. Implement Web Application Firewall (WAF) rules to block common SQL injection signatures in the doctorname field. Query your Hospital Management System audit logs for any data export or manipulation events coinciding with suspicious profile requests. Consider deploying application-level input validation logging to catch injection attempts before database execution.

Why prioritize this

Although CVE-2026-13542 scores MEDIUM (6.3) and requires authentication, prioritization should be elevated in healthcare settings due to PHI exposure risk, public exploit availability, and the critical nature of Hospital Management Systems. Authenticated users (including temporary staff, contractors, or compromised accounts) can manipulate patient-related data. Regulatory scrutiny under HIPAA and state breach notification laws makes this a business-critical fix, not just a technical patch.

Risk score, explained

CVSS 3.1 score 6.3 (MEDIUM) reflects: network-accessible attack vector (AV:N), low attack complexity (AC:L), requirement for low-level authentication (PR:L), no user interaction (UI:N), and impact scoped to the vulnerable component (S:U). Confidentiality, integrity, and availability are all low (L). The score does not account for healthcare regulatory context, data sensitivity, or the fact that public disclosure and exploit availability lower the barrier for attackers. In a healthcare risk model, functional impact should be weighted higher.
