SQL Injection in Hospital Management System 1.0

Executive Summary

CVE-2026-13532 is a SQL injection vulnerability found in the Hospital Management System 1.0, specifically in the /departmentDoctor.php file. The vulnerability arises because the 'deptid' parameter is not properly sanitized or validated, allowing an attacker to inject malicious SQL queries.

Exploitation requires the attacker to have valid credentials (authentication) to access the system. Once inside, the attacker can manipulate SQL queries using techniques such as boolean-based blind, error-based, time-based blind, and UNION query attacks.

This vulnerability enables unauthorized operations like accessing sensitive data, tampering with data, gaining extensive control over the system, or causing service interruptions.

Detection Guidance

The vulnerability in the Hospital Management System 1.0 is an SQL injection in the /departmentDoctor.php file via the 'deptid' parameter, which requires authentication to exploit.

Detection can involve testing the 'deptid' parameter for SQL injection vulnerabilities using techniques such as boolean-based blind, error-based, time-based blind, and UNION query attacks.

Common commands or tools to detect this vulnerability include using SQL injection testing tools like sqlmap with authentication credentials to test the 'deptid' parameter, for example:

• sqlmap -u "http://target/departmentDoctor.php?deptid=1" --cookie="SESSION=your_session_cookie" --batch
• Manually testing by injecting SQL payloads into the 'deptid' parameter after logging in, such as appending ' OR '1'='1' -- to the parameter value and observing the response.

Network detection could also involve monitoring for unusual database query patterns or error messages related to SQL injection attempts targeting the 'deptid' parameter.

Mitigation Strategies

Immediate mitigation steps for this SQL injection vulnerability include:

• Implement prepared statements and parameterized queries to prevent direct injection of malicious SQL code.
• Apply strict input validation and filtering on the 'deptid' parameter to ensure only expected values are accepted.
• Minimize database user permissions to limit the impact of a potential SQL injection attack.
• Conduct regular security audits and code reviews focusing on input handling and database interactions.

Additionally, monitor logs for suspicious activity and consider temporarily restricting access to the vulnerable functionality until a patch is applied.

Compliance Impact

The SQL injection vulnerability in the Hospital Management System 1.0 allows attackers to access and manipulate sensitive data, which could lead to unauthorized disclosure or alteration of personal health information.

Such unauthorized access and data manipulation can result in non-compliance with regulations like GDPR and HIPAA, which mandate the protection of personal and health-related data against breaches and unauthorized access.

Therefore, this vulnerability poses a risk to maintaining compliance with these common standards and regulations by potentially exposing sensitive patient information and compromising data integrity.
