CVE-2014-0468
📋 TL;DR
This vulnerability in FusionForge's Apache configuration allows remote code execution by enabling attackers to execute arbitrary scripts uploaded to SCM repositories (SVN, Git, Bzr). It affects all FusionForge installations with default configurations before version 5.3+20140506, potentially compromising the entire web server.
💻 Affected Systems
- FusionForge
📦 What is this software?
Fusionforge by Fusionforge
⚠️ Risk & Real-World Impact
Worst Case
Complete server compromise allowing attackers to execute arbitrary code, steal data, install backdoors, and pivot to other systems in the network.
Likely Case
Remote code execution leading to web server compromise, data theft, and potential lateral movement within the network.
If Mitigated
Limited impact with proper access controls and monitoring, potentially only affecting the web application's data.
🎯 Exploit Status
Exploitation requires uploading malicious scripts to SCM repositories, which may require some user privileges depending on configuration.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 5.3+20140506 or later
Vendor Advisory: http://lists.fusionforge.org/pipermail/fusionforge-general/2014-March/002645.html
Restart Required: Yes
Instructions:
1. Upgrade FusionForge to version 5.3+20140506 or later. 2. Restart Apache web server. 3. Verify the fix by checking version and testing SCM repository access.
🔧 Temporary Workarounds
Restrict SCM Repository Access
linuxModify Apache configuration to prevent execution of scripts in SCM repositories
Edit Apache configuration to add: <Location /scm/>\n SetHandler None\n Options -ExecCGI\n RemoveHandler .cgi .pl .py .php\n</Location>
sudo systemctl restart apache2
Disable SCM Functionality
linuxTemporarily disable SCM (SVN, Git, Bzr) functionality in FusionForge
Edit FusionForge configuration to disable SCM plugins
Restart Apache web server
🧯 If You Can't Patch
- Implement strict file upload restrictions and validation for SCM repositories
- Deploy web application firewall (WAF) rules to block script execution in repository paths
🔍 How to Verify
Check if Vulnerable:
Check FusionForge version and examine Apache configuration for SCM repository handlingCheck Version:
grep 'FusionForge' /usr/share/fusionforge/VERSION || find / -name 'VERSION' -exec grep FusionForge {} \;Verify Fix Applied:
Verify version is 5.3+20140506 or later and test that scripts in SCM repositories cannot be executed📡 Detection & Monitoring
Log Indicators:
- Unusual file uploads to SCM repositories
- Execution of scripts from SCM paths in Apache logs
- HTTP requests to /scm/*.cgi, /scm/*.pl, /scm/*.py
Network Indicators:
- HTTP POST requests uploading files to SCM endpoints
- HTTP GET requests executing scripts from repository paths
