CVE-2025-2373
📋 TL;DR
This critical SQL injection vulnerability in PHPGurukul Human Metapneumovirus Testing Management System 1.0 allows attackers to manipulate database queries through the mobnumber/employeeid parameters in check_availability.php. Remote attackers can potentially read, modify, or delete sensitive medical testing data. All users running version 1.0 without proper input validation are affected.
💻 Affected Systems
- PHPGurukul Human Metapneumovirus Testing Management System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to exposure of all patient medical records, testing results, and personal information; potential for data destruction or ransomware deployment.
Likely Case
Unauthorized access to sensitive patient data, including medical testing results and personal information; potential for data exfiltration.
If Mitigated
Limited impact with proper input validation and database permissions; failed exploitation attempts logged for monitoring.
🎯 Exploit Status
Exploit details are publicly disclosed; SQL injection via mobnumber/employeeid parameters is straightforward for attackers with basic skills.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://phpgurukul.com/
Restart Required: No
Instructions:
1. Check vendor website for security updates. 2. If no patch available, implement input validation and parameterized queries. 3. Consider migrating to alternative software if vendor support is unavailable.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement server-side validation and sanitization of mobnumber and employeeid parameters before processing.
// PHP example: Use prepared statements with PDO or mysqli
$stmt = $pdo->prepare('SELECT * FROM users WHERE mobnumber = :mobnumber');
$stmt->execute(['mobnumber' => $sanitized_input]);
Web Application Firewall (WAF) Rules
allDeploy WAF rules to block SQL injection patterns targeting check_availability.php.
# Example ModSecurity rule
SecRule ARGS "@detectSQLi" "id:1001,phase:2,deny,status:403,msg:'SQL Injection Attempt'"
🧯 If You Can't Patch
- Isolate the system from internet access and restrict to internal network only
- Implement strict network segmentation and monitor all database access attempts
🔍 How to Verify
Check if Vulnerable:
Test check_availability.php with SQL injection payloads in mobnumber/employeeid parameters (e.g., ' OR '1'='1). Use tools like sqlmap with caution: sqlmap -u 'http://target/check_availability.php?mobnumber=test' --dbsCheck Version:
Check system documentation or admin panel for version information; examine source code headers or configuration files.Verify Fix Applied:
Attempt SQL injection tests after implementing fixes; verify no database errors or unexpected data returns. Check that prepared statements are properly implemented.📡 Detection & Monitoring
Log Indicators:
- Unusual database query patterns in PHP/application logs
- Multiple failed login attempts or parameter manipulation in access logs
- SQL syntax errors in application error logs
Network Indicators:
- Unusual outbound database connections from web server
- Large data transfers from database to external IPs
- Repeated requests to check_availability.php with suspicious parameters
SIEM Query:
source="web_logs" AND (url="*check_availability.php*" AND (param="*mobnumber*" OR param="*employeeid*") AND (value="*' OR*" OR value="*;--*" OR value="*UNION*"))
