CVE-2025-4028
📋 TL;DR
This critical SQL injection vulnerability in PHPGurukul COVID19 Testing Management System 1.0 allows attackers to execute arbitrary SQL commands via the mobilenumber parameter in profile.php. Remote attackers can potentially access, modify, or delete database content. All users of version 1.0 are affected.
💻 Affected Systems
- PHPGurukul COVID19 Testing Management System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including data theft, data destruction, authentication bypass, and potential remote code execution via database functions.
Likely Case
Unauthorized data access and extraction of sensitive COVID-19 testing records, patient information, and system credentials.
If Mitigated
Limited impact with proper input validation and database permissions, potentially only read access to non-sensitive data.
🎯 Exploit Status
Exploit details are publicly available on GitHub, making this easily exploitable by attackers with basic SQL injection knowledge.
🛠️ 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
allImplement strict input validation and parameterized queries for the mobilenumber parameter in profile.php
Modify profile.php to use prepared statements: $stmt = $conn->prepare('SELECT * FROM users WHERE mobilenumber = ?'); $stmt->bind_param('s', $mobilenumber);
Web Application Firewall (WAF)
allDeploy WAF rules to block SQL injection patterns targeting the profile.php endpoint
Add WAF rule: Block requests to /profile.php containing SQL keywords like UNION, SELECT, INSERT, DELETE, DROP, OR 1=1
🧯 If You Can't Patch
- Isolate the system from internet access and restrict to internal network only
- Implement strict network segmentation and monitor all traffic to/from the affected system
🔍 How to Verify
Check if Vulnerable:
Test the /profile.php endpoint with SQL injection payloads in the mobilenumber parameter (e.g., ' OR '1'='1)Check Version:
Check system documentation or about page for version informationVerify Fix Applied:
Verify that SQL injection payloads no longer work and that parameterized queries are implemented in profile.php📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in application logs
- Multiple failed login attempts from profile.php
- Requests to profile.php with SQL keywords in parameters
Network Indicators:
- Unusual database connection patterns
- Large data transfers from the application server
SIEM Query:
source="web_logs" AND uri="/profile.php" AND (param="mobilenumber" AND value MATCHES "(?i)(union|select|insert|delete|drop|or.*=.*)")
