A critical SQL injection vulnerability in the phpgurukul Hospital Management System exposes the backend database to unauthorized access and potential data exfiltration.

This is a SQL injection vulnerability located in the index.php script. The vulnerability allows an unauthenticated attacker to manipulate the username parameter to execute arbitrary SQL commands against the underlying database.

The vulnerability carries a CVSS score of 9.8, indicating a critical risk to data confidentiality, integrity, and availability. Successful exploitation could lead to full database compromise, resulting in the theft of sensitive patient information, unauthorized administrative access, or complete system takeover.

Immediate Action: Upgrade to the latest version of the Hospital Management System provided by phpgurukul to incorporate the necessary input sanitization patches.

Proactive Monitoring: Review web server access logs for anomalous request patterns, particularly those containing SQL syntax characters (e.g., ', --, UNION) directed at index.php.

Compensating Controls: Deploy a Web Application Firewall (WAF) with strict SQL injection filtering rules to block malicious payloads targeting the username parameter.

Public Exploit Available: Not specified

Given the critical severity of this SQL injection vulnerability, immediate action is required to patch the affected system. Organizations should prioritize updating the software and auditing database access logs to ensure no unauthorized activity has already occurred.
