CVE-2025-4021
📋 TL;DR
CVE-2025-4021 is a critical SQL injection vulnerability in code-projects Patient Record Management System 1.0 that allows remote attackers to execute arbitrary SQL commands via the ID parameter in /edit_spatient.php. This affects all organizations using this specific software version, potentially exposing sensitive patient records and system data.
💻 Affected Systems
- code-projects Patient Record Management System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to patient record theft, data destruction, and potential remote code execution on the database server.
Likely Case
Unauthorized access to patient records, extraction of sensitive data, and potential privilege escalation within the application.
If Mitigated
Limited impact due to proper input validation, parameterized queries, and network segmentation preventing database access.
🎯 Exploit Status
Exploit details are publicly disclosed on GitHub, making exploitation straightforward for attackers with basic SQL injection knowledge.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://code-projects.org/
Restart Required: No
Instructions:
No official patch available. Consider implementing workarounds or migrating to a different patient management system.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement strict input validation for the ID parameter to only accept expected formats (e.g., numeric values)
Modify /edit_spatient.php to validate ID parameter using regex: if (!preg_match('/^\d+$/', $_GET['ID'])) { die('Invalid input'); }
Parameterized Queries Implementation
allReplace dynamic SQL queries with prepared statements using PDO or MySQLi
Replace: $query = "SELECT * FROM patients WHERE id = " . $_GET['ID']; with: $stmt = $pdo->prepare("SELECT * FROM patients WHERE id = ?"); $stmt->execute([$_GET['ID']]);
🧯 If You Can't Patch
- Implement a Web Application Firewall (WAF) with SQL injection rules to block malicious requests
- Restrict network access to the application using firewall rules and segment the database server
🔍 How to Verify
Check if Vulnerable:
Test the /edit_spatient.php endpoint with SQL injection payloads like: /edit_spatient.php?ID=1' OR '1'='1Check Version:
Check application version in configuration files or about pageVerify Fix Applied:
Test with the same payloads after implementing fixes - should return error or no data instead of executing SQL📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in application logs
- Multiple failed parameter validation attempts
- Requests with SQL keywords in ID parameter
Network Indicators:
- HTTP requests containing SQL injection patterns to /edit_spatient.php
- Unusual database query patterns from application server
SIEM Query:
source="web_logs" AND uri="/edit_spatient.php" AND (query="*OR*" OR query="*UNION*" OR query="*SELECT*" OR query="*'*" OR query="*--*" OR query="*;*")
