Executive Summary

[{'type': 'paragraph', 'content': "CVE-2026-2179 is a SQL Injection vulnerability in PHPGurukul Hospital Management System version 4.0, specifically in the admin module file /admin/manage-users.php. The vulnerability occurs because the application directly uses the 'id' parameter from the URL query string without any input validation or sanitization and concatenates it into a SQL DELETE statement. This allows an attacker to inject arbitrary SQL commands remotely."}, {'type': 'paragraph', 'content': "The vulnerable code executes a SQL DELETE query like: delete from users where id ='$uid', where $uid is directly taken from user input. An attacker can manipulate this to execute destructive commands such as deleting the entire users table or extracting sensitive data using blind SQL injection techniques."}, {'type': 'paragraph', 'content': 'Proof-of-concept exploits demonstrate time-based blind SQL injection payloads that delay server responses, confirming successful injection. Automated tools like SQLMap and Burp Suite have validated the vulnerability, showing that attackers can extract sensitive database information and cause denial of service.'}] [1, 2, 3]

Impact Analysis

[{'type': 'paragraph', 'content': 'This vulnerability can have several serious impacts including unauthorized deletion of data, disclosure of sensitive information, and denial of service.'}, {'type': 'list_item', 'content': 'Attackers can delete entire user tables or other critical data by injecting destructive SQL commands.'}, {'type': 'list_item', 'content': 'Sensitive database information such as user credentials and database details can be extracted by attackers.'}, {'type': 'list_item', 'content': "The system's confidentiality, integrity, and availability are compromised, potentially disrupting hospital management operations."}, {'type': 'list_item', 'content': 'Because the attack can be initiated remotely, it increases the risk of exploitation without physical access.'}] [1, 2, 3]

Detection Guidance

[{'type': 'paragraph', 'content': 'This SQL Injection vulnerability in PHPGurukul Hospital Management System 4.0 can be detected by testing the vulnerable URL parameter `id` in the file `/admin/manage-users.php` for injection flaws.'}, {'type': 'paragraph', 'content': 'A common detection method is to use time-based blind SQL injection payloads in the URL to observe response delays indicating successful injection.'}, {'type': 'paragraph', 'content': 'Example command using curl to test the vulnerability by injecting a time delay payload:'}, {'type': 'list_item', 'content': 'curl "http://localhost/hospital/hms/admin/manage-users.php?id=1\' AND (SELECT 1 FROM (SELECT(SLEEP(5)))a)--+&del=delete"'}, {'type': 'paragraph', 'content': 'If the server response is delayed by approximately 5 seconds, it confirms the presence of the SQL injection vulnerability.'}, {'type': 'paragraph', 'content': 'Automated tools like SQLMap can also be used to detect and exploit this vulnerability, for example:'}, {'type': 'list_item', 'content': 'sqlmap -u "http://localhost/hospital/hms/admin/manage-users.php?id=1&del=delete" --delay=5 --technique=BEUSTQ'}, {'type': 'paragraph', 'content': 'Burp Suite can be used to manually test and confirm the injection by sending crafted requests with time-based payloads.'}] [1]

Mitigation Strategies

Immediate mitigation steps for this SQL Injection vulnerability include:

• Implement prepared statements with parameter binding (e.g., using `prepare` and `bind_param` in PHP) to separate SQL code from user input.
• Apply integer casting to the `id` parameter before using it in SQL queries, for example, using `intval()` in PHP to ensure only numeric input is processed.
• Restrict access to the vulnerable admin module to trusted users only and enforce strong authentication.
• Monitor and block suspicious requests that attempt to inject SQL commands, especially those containing typical SQL injection payloads.

Long-term remediation involves updating the application code to securely handle user inputs and avoid direct concatenation of parameters into SQL queries.
