CVE-2025-6157
📋 TL;DR
A critical SQL injection vulnerability exists in PHPGurukul Nipah Virus Testing Management System 1.0. Attackers can remotely exploit the /registered-user-testing.php file by manipulating the 'testtype' parameter to execute arbitrary SQL commands. This affects all deployments of version 1.0 of this healthcare management system.

📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, data manipulation, or complete system takeover via SQL injection to RCE chaining.
Likely Case
Unauthorized access to sensitive patient testing data, administrative credentials theft, and database manipulation.
If Mitigated
Limited impact with proper input validation and WAF rules blocking SQL injection patterns.
🎯 Exploit Status
Exploit details are publicly available on GitHub. Attack requires access to registered user functionality but doesn't require admin privileges.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://phpgurukul.com/
Restart Required: No
Instructions:
No official patch available. Consider migrating to alternative software or implementing workarounds.
🔧 Temporary Workarounds
Input Validation and Sanitization
allAdd parameterized queries and input validation to /registered-user-testing.php
Modify PHP code to use prepared statements: $stmt = $conn->prepare('SELECT * FROM tests WHERE testtype = ?'); $stmt->bind_param('s', $testtype);
WAF Rule Implementation
linuxDeploy web application firewall rules to block SQL injection patterns
For ModSecurity: SecRule ARGS:testtype "@detectSQLi" "id:1001,phase:2,deny,status:403"
🧯 If You Can't Patch
- Isolate the system behind a reverse proxy with strict WAF rules blocking SQL injection patterns
- Implement network segmentation to limit database access only to necessary application servers
🔍 How to Verify
Check if Vulnerable:
Test the /registered-user-testing.php endpoint with SQL injection payloads in the testtype parameter (e.g., testtype=' OR '1'='1)Check Version:
Check system documentation or about page; version may be displayed in footer or admin panelVerify Fix Applied:
Verify that SQL injection payloads no longer execute and return proper error handling📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in database logs
- Multiple failed login attempts following SQL injection patterns
- HTTP requests with SQL keywords in testtype parameter
Network Indicators:
- HTTP POST requests to /registered-user-testing.php containing SQL injection payloads
- Unusual database connection patterns from web server
SIEM Query:
source="web_logs" AND uri="/registered-user-testing.php" AND (testtype="*OR*" OR testtype="*UNION*" OR testtype="*SELECT*" OR testtype="*--*")
