CVE-2025-56215
📋 TL;DR
This SQL injection vulnerability in phpgurukul Hospital Management System 4.0 allows attackers to manipulate database queries through the pagetitle parameter in contact.php. Attackers could potentially extract, modify, or delete sensitive hospital data including patient records. All organizations using the vulnerable version are affected.
💻 Affected Systems
- phpgurukul Hospital Management System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to exposure of all patient medical records, financial data, and administrative credentials, potentially enabling ransomware deployment or data destruction.
Likely Case
Extraction of sensitive patient information (PII/PHI), administrative credentials, and potential database manipulation affecting hospital operations.
If Mitigated
Limited data exposure if proper input validation and WAF rules are in place, with minimal operational impact.
🎯 Exploit Status
SQL injection requires understanding of the application's database structure but is a well-known attack vector with many available tools.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Version 4.1 or later
Vendor Advisory: https://www.phpgurukul.com/security-advisory/
Restart Required: No
Instructions:
1. Download the latest version from phpgurukul official website. 2. Backup your current installation and database. 3. Replace the vulnerable contact.php file with the patched version. 4. Test the application functionality.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement strict input validation and parameterized queries for the pagetitle parameter
Modify contact.php to use prepared statements: $stmt = $conn->prepare('SELECT * FROM contacts WHERE pagetitle = ?'); $stmt->bind_param('s', $pagetitle);
Web Application Firewall Rules
allDeploy WAF rules to block SQL injection patterns in the pagetitle parameter
Add WAF rule: SecRule ARGS:pagetitle "@detectSQLi" "id:1001,phase:2,deny,status:403"
🧯 If You Can't Patch
- Implement network segmentation to isolate the hospital management system from other critical networks
- Deploy database activity monitoring to detect and alert on suspicious SQL queries
🔍 How to Verify
Check if Vulnerable:
Test the contact.php endpoint with SQL injection payloads like ' OR '1'='1 in the pagetitle parameter and observe if database errors or unexpected results occur.Check Version:
Check the application's admin panel or read the version.txt file in the installation directoryVerify Fix Applied:
Attempt the same SQL injection tests after patching; successful fixes should return proper error handling without database exposure.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in application logs
- Multiple failed login attempts following SQL injection patterns
- Unexpected database query patterns
Network Indicators:
- HTTP requests containing SQL keywords (SELECT, UNION, etc.) in pagetitle parameter
- Abnormal traffic patterns to contact.php endpoint
SIEM Query:
source="web_logs" AND (url="*contact.php*" AND (param="*pagetitle=*SELECT*" OR param="*pagetitle=*UNION*" OR param="*pagetitle=*OR*"))
