CVE-2026-13532: SQL Injection in itsourcecode Hospital Management System 1.0

Technical summary

CVE-2026-13532 is a SQL injection vulnerability (CWE-89, CWE-74) affecting itsourcecode Hospital Management System 1.0. The vulnerability exists in /departmentDoctor.php where user-supplied input in the deptid parameter is not properly sanitized before being incorporated into SQL queries. The attack vector is network-based and requires low-privilege authentication. No special interaction or unusual configuration is needed to trigger the vulnerability. CVSS 3.1 score of 6.3 (MEDIUM) reflects confidentiality, integrity, and availability impact with low privileges required.

Business impact

A successful exploit could allow attackers with staff credentials to access patient records, modify treatment histories, delete critical medical information, or insert false data into the hospital database. This poses direct risks to patient safety, regulatory compliance (HIPAA, similar healthcare regulations), operational continuity, and institutional liability. In a hospital environment, data integrity breaches can have life-threatening consequences if treatment records are altered without detection.

Affected systems

itsourcecode Hospital Management System version 1.0 is affected. Organizations running this specific version should immediately identify all deployments within their environment, including dev, test, and production instances. If vendor information indicates later versions exist, those should be verified as patched or evaluated separately.

Exploitability

Exploitation requires valid authentication credentials, which moderates immediate risk in isolated networks but increases risk significantly in shared or internet-facing deployments where credential compromise may already exist. Public availability of exploit code removes complexity barriers and enables rapid weaponization. The low attack complexity and network accessibility make this practical for motivated threat actors with even basic SQL injection knowledge.

Remediation

Immediate remediation requires either upgrading to a patched version released by itsourcecode (verify against official vendor advisory) or implementing input validation and parameterized queries for the deptid parameter in /departmentDoctor.php. As an interim control pending patching, restrict network access to the Hospital Management System and enforce strong authentication policies. Monitor database logs for suspicious SQL activity.

Patch guidance

Contact itsourcecode directly or consult their official security advisories to obtain available patches for Hospital Management System 1.0. Verify patch version numbers and compatibility before applying updates. Test patches in a non-production environment to confirm functionality, particularly around department and doctor record queries. If no patch is available, evaluate options to upgrade to a newer version of the software or consider security compensating controls such as Web Application Firewall (WAF) rules that detect and block SQL injection patterns.

Detection guidance

Monitor database activity logs for unusual SQL queries originating from the /departmentDoctor.php endpoint, particularly those containing SQL keywords (UNION, SELECT, DROP, INSERT) within the deptid parameter values. Enable query logging on the backend database. Review authentication logs for access from unexpected locations or times. Network-based detection should flag HTTP requests with SQL metacharacters in the deptid parameter. Apply these detection rules across all instances of Hospital Management System 1.0 in your environment.

Why prioritize this

Although CVSS 6.3 indicates medium severity, this vulnerability warrants priority attention in healthcare environments due to the intersection of public exploit availability, authentication-bypass potential through compromised credentials, and critical data sensitivity. Hospital systems handling patient records face heightened regulatory scrutiny and operational risk. The combination of available exploit code and moderate technical barrier makes this a practical target for attackers, particularly those targeting healthcare organizations.

Risk score, explained

The CVSS 3.1 score of 6.3 (MEDIUM) reflects: network attack vector (AV:N), low attack complexity (AC:L), requirement for low-level user privileges (PR:L), no user interaction (UI:N), unchanged scope (S:U), and partial impact to confidentiality, integrity, and availability (C:L/I:L/A:L). The score appropriately captures the authentication requirement but may underweight operational risk in healthcare contexts; organizations should layer additional context around data sensitivity and regulatory obligations.
