CVE-2024-41373
📋 TL;DR
CVE-2024-41373 is a path traversal vulnerability in ICEcoder 8.1 that allows attackers to read arbitrary files on the server via lib/backup-versions-preview-loader.php. This affects all ICEcoder 8.1 installations with the vulnerable component accessible. Attackers can potentially access sensitive configuration files, source code, or system files.
💻 Affected Systems
- ICEcoder
📦 What is this software?
Icecoder by Icecoder
⚠️ Risk & Real-World Impact
Worst Case
Full server compromise through reading sensitive files like configuration files containing database credentials, SSH keys, or other authentication secrets, leading to lateral movement or data exfiltration.
Likely Case
Unauthorized access to application source code, configuration files, or other sensitive files stored within the web root or accessible paths, potentially exposing credentials or intellectual property.
If Mitigated
Limited impact with proper file permissions, web server restrictions, and network segmentation preventing access to critical system files.
🎯 Exploit Status
The exploit requires sending crafted HTTP requests to the vulnerable endpoint. Public proof-of-concept demonstrates simple path traversal payloads.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: Not available
Restart Required: No
Instructions:
1. Upgrade to a version beyond 8.1 if available. 2. If no patch exists, apply workarounds or remove vulnerable component. 3. Monitor official ICEcoder channels for security updates.
🔧 Temporary Workarounds
Remove vulnerable file
linuxDelete or rename the lib/backup-versions-preview-loader.php file to prevent exploitation.
rm /path/to/icecoder/lib/backup-versions-preview-loader.php
Restrict access via web server
allConfigure web server (Apache/Nginx) to block access to the vulnerable endpoint.
# Apache: <Location "/lib/backup-versions-preview-loader.php">
Require all denied
</Location>
# Nginx: location ~ /lib/backup-versions-preview-loader\.php$ { return 403; }
🧯 If You Can't Patch
- Implement strict file permissions to limit readable files to only necessary directories.
- Deploy web application firewall (WAF) rules to block path traversal patterns in requests.
🔍 How to Verify
Check if Vulnerable:
Attempt to access http://[icecoder-url]/lib/backup-versions-preview-loader.php?file=../../../../etc/passwd (or similar traversal). If it returns file contents, the system is vulnerable.Check Version:
Check ICEcoder version in the admin interface or review source files for version markers.Verify Fix Applied:
After applying fixes, repeat the check; requests should return 403/404 errors or no file content.📡 Detection & Monitoring
Log Indicators:
- HTTP requests containing '..' or '../' patterns targeting lib/backup-versions-preview-loader.php
- Unusual file access patterns from web server logs
Network Indicators:
- HTTP GET requests with path traversal payloads to the vulnerable endpoint
