CVE-2024-53604
📋 TL;DR
A SQL injection vulnerability in PHPGurukul COVID 19 Testing Management System v1.0 allows remote attackers to execute arbitrary SQL commands via the mobnumber parameter in the check_availability.php endpoint. This can lead to database compromise, data theft, or complete system takeover. Organizations using this specific version of the COVID testing management system are affected.
💻 Affected Systems
- PHPGurukul COVID 19 Testing Management System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data exfiltration, privilege escalation to administrative access, and potential remote code execution on the underlying server.
Likely Case
Unauthorized access to sensitive COVID testing data including patient records, test results, and personal information, potentially leading to data breach and regulatory violations.
If Mitigated
Limited impact with proper input validation and parameterized queries preventing SQL injection, though system may still be vulnerable to other attacks.
🎯 Exploit Status
The vulnerability requires no authentication and can be exploited with basic SQL injection techniques. Public proof-of-concept documentation exists.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch available. Consider migrating to alternative COVID testing management systems or implementing custom security fixes.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement strict input validation for the mobnumber parameter to only accept valid phone number formats
Modify check_availability.php to validate mobnumber parameter using regex: /^[0-9]{10}$/
Parameterized Queries Implementation
allReplace direct SQL string concatenation with prepared statements using PDO or mysqli
Replace vulnerable SQL code with prepared statements: $stmt = $conn->prepare('SELECT * FROM users WHERE mobnumber = ?'); $stmt->bind_param('s', $mobnumber);
🧯 If You Can't Patch
- Implement a web application firewall (WAF) with SQL injection protection rules
- Restrict network access to the vulnerable endpoint using firewall rules or authentication
🔍 How to Verify
Check if Vulnerable:
Send a POST request to /covid-tms/check_availability.php with mobnumber parameter containing SQL injection payload like ' OR '1'='1
Check Version:
Check system documentation or about page for version information, or examine PHP file headers
Verify Fix Applied:
Test with SQL injection payloads and verify they are rejected or sanitized without affecting database queries
📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in web server logs
- Multiple failed login attempts or unusual parameter values in access logs
Network Indicators:
- HTTP POST requests to /covid-tms/check_availability.php with SQL keywords in parameters
- Unusual database query patterns from web server IP
SIEM Query:
source="web_server" AND (url_path="/covid-tms/check_availability.php" AND (param="mobnumber" AND value CONTAINS "' OR" OR value CONTAINS "UNION" OR value CONTAINS "SELECT"))
