CVE-2025-4306: Phpgurukul Nipah Virus System SQLi Flaw

CVE-2025-4306 Overview

A critical SQL injection vulnerability has been identified in PHPGurukul Nipah Virus Testing Management System version 1.0. The vulnerability exists in the /edit-phlebotomist.php file, where improper handling of the mobilenumber parameter allows attackers to inject malicious SQL queries. This flaw can be exploited remotely without authentication, potentially compromising the integrity and confidentiality of the healthcare management database. The exploit has been publicly disclosed, increasing the risk of active exploitation.

Critical Impact
Remote attackers can exploit this SQL injection vulnerability to extract sensitive healthcare data, modify patient records, or potentially gain unauthorized access to the underlying database server hosting the Nipah virus testing management system.

Affected Products

PHPGurukul Nipah Virus Testing Management System 1.0

Technical Details for CVE-2025-4306

Vulnerability Analysis

This SQL injection vulnerability (CWE-89) stems from insufficient input validation in the phlebotomist editing functionality. When processing the mobilenumber parameter in /edit-phlebotomist.php, the application fails to properly sanitize user-supplied input before incorporating it into SQL queries. This allows attackers to inject arbitrary SQL commands that execute with the privileges of the database user.

The vulnerability is classified under both CWE-89 (Improper Neutralization of Special Elements used in an SQL Command) and CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), indicating multiple injection pathways. The public disclosure notes that other parameters in this file may also be vulnerable to similar injection attacks.

Root Cause

The root cause is improper input validation and lack of parameterized queries in the PHP application. The mobilenumber parameter is directly concatenated into SQL statements without proper escaping or the use of prepared statements. This fundamental flaw in secure coding practices allows user input to break out of the intended data context and execute as SQL commands.

Attack Vector

The attack can be executed remotely over the network without requiring authentication. An attacker crafts a malicious HTTP request to /edit-phlebotomist.php containing SQL injection payloads in the mobilenumber parameter. The injection can be performed through standard web requests, making it accessible to any attacker with network access to the vulnerable application.

The vulnerability allows for blind SQL injection techniques where attackers can extract database contents character by character, or time-based injection to infer database structure. Given the healthcare context of this application, successful exploitation could expose protected health information (PHI) and patient test results related to Nipah virus testing.

Detection Methods for CVE-2025-4306

Indicators of Compromise

Unusual SQL error messages in web server logs from /edit-phlebotomist.php
HTTP requests containing SQL keywords (UNION, SELECT, DROP, etc.) in the mobilenumber parameter
Database query logs showing unexpected queries or access patterns from the web application
Abnormal database access times indicating time-based SQL injection attempts

Detection Strategies

Deploy Web Application Firewall (WAF) rules to detect SQL injection patterns in requests to /edit-phlebotomist.php
Monitor web server access logs for requests containing encoded SQL injection payloads
Implement database activity monitoring to detect anomalous query patterns
Configure intrusion detection systems (IDS) with signatures for common SQL injection attack patterns

Monitoring Recommendations

Enable detailed logging for all requests to the PHPGurukul application
Set up alerts for failed database queries indicating potential injection attempts
Monitor for data exfiltration patterns from the healthcare database
Review access logs for repeated requests to the vulnerable endpoint with varying parameter values

How to Mitigate CVE-2025-4306

Immediate Actions Required

Restrict network access to the vulnerable /edit-phlebotomist.php endpoint until patched
Implement input validation at the web server or WAF level to block SQL injection patterns
Consider taking the application offline if it contains sensitive healthcare data and cannot be immediately secured
Review database logs for signs of prior exploitation

Patch Information

No official patch has been released by PHPGurukul at the time of this publication. Organizations using this software should monitor the PHPGurukul website for security updates. Additional technical details are available through the VulDB entry and the GitHub security disclosure.

Workarounds

Implement prepared statements and parameterized queries if source code modifications are possible
Deploy a Web Application Firewall with SQL injection prevention rules
Restrict access to the application to trusted IP addresses only
Add server-side input validation to reject non-numeric characters in the mobilenumber field
