CVE-2024-25183
📋 TL;DR
CVE-2024-25183 is a directory traversal vulnerability in givanz VvvebJs 1.7.2 that allows attackers to read arbitrary files on the server via the scan.php endpoint. This affects all systems running the vulnerable version of VvvebJs, a visual web page builder. Attackers can exploit this without authentication to access sensitive files.

⚠️ Risk & Real-World Impact
Worst Case
Complete server compromise through reading sensitive configuration files (like .env, config files) containing database credentials, API keys, or other secrets, potentially leading to data breach or further system exploitation.
Likely Case
Unauthorized access to sensitive files containing configuration data, source code, or user information, enabling reconnaissance for further attacks or data theft.
If Mitigated
Limited impact if proper file permissions restrict access to sensitive files and web server runs with minimal privileges.
🎯 Exploit Status
The exploit requires simple HTTP requests with directory traversal sequences. Public proof-of-concept demonstrates reading arbitrary files.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch available. Remove or restrict access to scan.php file. Consider upgrading to a newer version if available.
🔧 Temporary Workarounds
Remove scan.php file
linuxDelete or rename the vulnerable scan.php file to prevent exploitation
rm /path/to/vvvebjs/scan.php
Restrict access via web server configuration
allBlock access to scan.php using web server rules
# Apache: <Location "/scan.php"> Require all denied </Location>
# Nginx: location = /scan.php { deny all; }
🧯 If You Can't Patch
- Implement strict file permissions on sensitive directories and configuration files
- Deploy web application firewall (WAF) rules to block directory traversal patterns
🔍 How to Verify
Check if Vulnerable:
Test if accessing /scan.php?path=../../../etc/passwd returns system files. Use curl: curl -v 'http://target/scan.php?path=../../../etc/passwd'Check Version:
Check VvvebJs version in package.json or composer.json filesVerify Fix Applied:
Verify scan.php file no longer exists or returns access denied. Test same exploit attempt returns error.📡 Detection & Monitoring
Log Indicators:
- HTTP requests to scan.php with ../ sequences in parameters
- Unusual file access patterns from web server process
Network Indicators:
- HTTP GET requests containing directory traversal sequences (../) to scan.php endpoint
SIEM Query:
source="web_access_logs" AND uri="/scan.php" AND (query="*../*" OR query="*..%2f*")
