CVE-2024-33118
📋 TL;DR
LuckyFrameWeb v3.5.2 contains an arbitrary file read vulnerability in the fileDownload method of CommonController. This allows attackers to read sensitive files from the server filesystem without authentication. All deployments of LuckyFrameWeb v3.5.2 are affected.
💻 Affected Systems
- LuckyFrameWeb
📦 What is this software?
Luckyframeweb by Luckyframe
⚠️ Risk & Real-World Impact
Worst Case
Complete server compromise through reading sensitive configuration files, credentials, or private keys leading to lateral movement and data exfiltration.
Likely Case
Unauthorized access to sensitive application files, configuration data, and potentially user information stored on the filesystem.
If Mitigated
Limited to reading non-critical files if proper file permissions and access controls are implemented.
🎯 Exploit Status
Simple HTTP request manipulation required. No authentication needed. Public exploit details available in GitHub references.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch available. Upgrade to a newer version if available, or apply workarounds.
🔧 Temporary Workarounds
Input Validation and Path Sanitization
allAdd proper input validation to the fileDownload method to prevent directory traversal attacks.
Modify CommonController.java to validate file paths and restrict to allowed directories
Web Application Firewall Rules
allImplement WAF rules to block directory traversal patterns in requests.
Add WAF rule: deny requests containing '../' or similar path traversal patterns
🧯 If You Can't Patch
- Restrict network access to LuckyFrameWeb interface to trusted IPs only
- Implement strict file system permissions to limit what the application user can read
🔍 How to Verify
Check if Vulnerable:
Test by attempting to access /common/fileDownload?fileName=../../../../etc/passwd (or similar traversal) and checking if sensitive files are returned.Check Version:
Check application version in web interface or configuration filesVerify Fix Applied:
Attempt the same traversal attack after applying fixes - should return error or empty response.📡 Detection & Monitoring
Log Indicators:
- HTTP requests to /common/fileDownload with '../' patterns
- Unusual file access patterns from web application user
Network Indicators:
- HTTP GET requests with directory traversal sequences in parameters
SIEM Query:
source="web_server" AND uri="/common/fileDownload" AND (uri="*../*" OR params="*../*")
