CVE-2026-14717: SQL Injection in itsourcecode Hospital Management System 1.0

Technical summary

CVE-2026-14717 is a SQL injection flaw (CWE-89, CWE-74) in the /patientlogin.php endpoint of itsourcecode Hospital Management System 1.0. The loginid parameter lacks proper input validation and is directly interpolated into a database query without parameterized statements or escaping. The attack vector is network-accessible, requires low complexity exploitation, and demands prior authentication (PR:L). Successful injection permits an attacker to extract or tamper with database records, including patient identifiable information (PII), medical records, and system credentials.

Business impact

For healthcare organizations, this vulnerability directly threatens HIPAA and HITECH compliance by enabling unauthorized access to Protected Health Information (PHI). A compromised patient database can result in regulatory fines, mandatory breach notifications, reputational damage, and loss of patient trust. Attackers can also escalate privileges or access staff credentials, potentially enabling lateral movement within hospital networks and disrupting clinical workflows.

Affected systems

itsourcecode Hospital Management System version 1.0 is affected. No patch version information is available in public disclosures at this time; verify against the vendor advisory for patched versions and comprehensive affected-version inventory. Organizations running this application in production should immediately identify and audit all instances.

Exploitability

Exploitation is feasible and practical for an attacker with valid login credentials. The attack requires no special tools beyond standard SQL injection techniques. Public disclosure of the vulnerability increases real-world exploit risk. The low authentication barrier (PR:L) means compromised staff credentials or shared test accounts can serve as an initial foothold. No advanced exploitation techniques or user interaction is required.

Remediation

Immediately discontinue use of itsourcecode Hospital Management System 1.0 until a patched version is released and verified. If interim operation is unavoidable, apply strict network segmentation, disable remote access to /patientlogin.php, enforce principle-of-least-privilege access controls, and implement Web Application Firewall (WAF) rules to block common SQL injection patterns. Conduct a forensic audit of database logs to detect prior exploitation. Verify patch availability directly with the vendor before upgrading.

Patch guidance

Check the vendor's advisory portal for a security release addressing CVE-2026-14717. Apply patches to all production and non-production instances immediately upon availability. Before deploying, test patched versions in an isolated environment to ensure clinical functionality remains intact. Document the patch version applied and the date of deployment for compliance auditing.

Detection guidance

Monitor /patientlogin.php for suspicious loginid parameter values, such as SQL keywords (SELECT, UNION, OR, --), quotation marks, and comment syntax in access logs and WAF logs. Enable query logging on the underlying database and search for anomalous statements originating from the application user account. Correlate login attempt timestamps with unusual database access patterns. Host-based intrusion detection (HIDS) can flag process execution from the web server user spawning shell commands.

Why prioritize this

Although the CVSS score is MEDIUM (6.3), the healthcare context elevates risk significantly. SQL injection in a hospital system directly exposes PHI, regulatory non-compliance is immediate and costly, and authenticated access is often available to numerous staff members whose credentials may be weak or shared. Public exploit availability and the sensitivity of the data warrant urgent patching ahead of non-critical vulnerabilities.

Risk score, explained

The CVSS:3.1 score of 6.3 reflects a network-accessible, low-complexity attack requiring authentication, with limited impact (L) across confidentiality, integrity, and availability. However, this scoring does not account for the healthcare sector's regulatory obligations, the sensitive nature of patient data, or the likelihood that staff credentials are prevalent in the environment. From a healthcare-specific risk perspective, this vulnerability should be treated as HIGH priority despite the medium CVSS rating.
