CVE-2025-5857
📋 TL;DR
This critical SQL injection vulnerability in Patient Record Management System 1.0 allows remote attackers to execute arbitrary SQL commands via the itr_no parameter in urinalysis_record.php. This can lead to unauthorized data access, modification, or deletion of patient records. All systems running the affected software version are vulnerable.
💻 Affected Systems
- Patient Record Management System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of the database including theft of all patient records, deletion of critical medical data, and potential ransomware deployment through database manipulation.
Likely Case
Unauthorized access to patient records, modification of medical data, and potential extraction of sensitive personal health information.
If Mitigated
Limited impact with proper input validation and database permissions, potentially only error messages or minimal data exposure.
🎯 Exploit Status
Exploit details are publicly available in GitHub repositories, making this easily weaponizable by attackers.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://code-projects.org/
Restart Required: No
Instructions:
No official patch available. Consider implementing input validation and parameterized queries as workarounds.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement strict input validation for the itr_no parameter to only accept expected formats and sanitize all user inputs.
Modify urinalysis_record.php to add input validation: if(!preg_match('/^[0-9]+$/', $_GET['itr_no'])) { die('Invalid input'); }
Web Application Firewall (WAF)
allDeploy a WAF with SQL injection protection rules to block malicious requests targeting the vulnerable endpoint.
🧯 If You Can't Patch
- Isolate the system from the internet and restrict access to authorized internal users only.
- Implement network segmentation and monitor all traffic to /urinalysis_record.php for suspicious patterns.
🔍 How to Verify
Check if Vulnerable:
Test the urinalysis_record.php endpoint with SQL injection payloads in the itr_no parameter (e.g., ' OR '1'='1).Check Version:
Check the software version in the application interface or configuration files.Verify Fix Applied:
Verify that SQL injection payloads no longer execute and return appropriate error messages or are blocked.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in application logs
- Multiple failed login attempts or parameter manipulation in access logs
- Errors containing SQL syntax in error logs
Network Indicators:
- HTTP requests to /urinalysis_record.php with SQL keywords in parameters
- Unusual database connection patterns from the application server
SIEM Query:
source="web_logs" AND uri="/urinalysis_record.php" AND (param="itr_no" AND value MATCHES "(?i)(union|select|insert|update|delete|drop|or|and|--|#|;)")
