CVE-2022-24232
📋 TL;DR
This vulnerability allows attackers to include local PHP files in Hospital Patient Record Management System v1.0, potentially leading to arbitrary code execution. Attackers can upload or reference crafted PHP files to run malicious code on the server. This affects all deployments of version 1.0 of this specific healthcare management software.

⚠️ Risk & Real-World Impact
Worst Case
Full system compromise with attacker gaining complete control over the server, accessing sensitive patient records, and potentially pivoting to other systems in the network.
Likely Case
Data theft of patient records, installation of backdoors, defacement of the system, or ransomware deployment.
If Mitigated
Limited impact with proper file upload restrictions and web application firewall rules blocking malicious requests.
🎯 Exploit Status
The GitHub references suggest proof-of-concept code exists, making exploitation straightforward for attackers with basic skills.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Unknown
Restart Required: No
Instructions:
No official patch available. Consider migrating to alternative patient record management systems with active security support.
🔧 Temporary Workarounds
Restrict File Uploads
allConfigure web server to block PHP file uploads and execution from untrusted directories
# In Apache .htaccess:
<FilesMatch "\.php$">
Deny from all
</FilesMatch>
# In nginx config:
location ~ \.php$ {
deny all;
}
Implement Input Validation
allAdd server-side validation to reject file paths containing directory traversal sequences
# PHP example:
if (strpos($input, '../') !== false || strpos($input, '..\\') !== false) {
die('Invalid file path');
}
🧯 If You Can't Patch
- Isolate the system on a segmented network with strict firewall rules limiting inbound/outbound connections
- Implement web application firewall (WAF) rules to block requests with suspicious file inclusion patterns
🔍 How to Verify
Check if Vulnerable:
Test if the application accepts file paths with directory traversal sequences (e.g., ../../etc/passwd) in file inclusion parametersCheck Version:
Check application version in admin panel or configuration filesVerify Fix Applied:
Attempt the same exploitation techniques after implementing workarounds to confirm they are blocked📡 Detection & Monitoring
Log Indicators:
- HTTP requests containing '../' sequences in parameters
- Unusual file access patterns to PHP files outside web root
- Multiple failed attempts to access system files
Network Indicators:
- Unusual outbound connections from the web server
- Traffic patterns matching known exploit payloads
