🔧 Temporary Workarounds
Web Application Firewall Rule
linuxBlock or sanitize requests containing shell metacharacters in the filename parameter
# Example mod_security rule: SecRule ARGS:filename "[;|&`$()]" "deny,status:403"
Access Restriction
linuxRestrict access to /fog/management/export.php endpoint to trusted IP addresses only
# Apache: <Location "/fog/management/export.php">
Require ip 192.168.1.0/24
</Location>
# Nginx: location /fog/management/export.php {
allow 192.168.1.0/24;
deny all;
}
🧯 If You Can't Patch
- Disable or block access to the /fog/management/export.php endpoint completely
- Implement strict network segmentation to isolate FOG servers from critical infrastructure
🔍 How to Verify
Check if Vulnerable:
Check if FOG version is below 1.5.10.34 by examining the web interface footer or running: cat /var/www/html/fog/version.php | grep FOG_VERSIONCheck Version:
grep "define.*FOG_VERSION" /var/www/html/fog/version.phpVerify Fix Applied:
Verify version is 1.5.10.34 or higher and test that command injection attempts are properly sanitized or blocked📡 Detection & Monitoring
Log Indicators:
- Unusual POST requests to /fog/management/export.php with shell metacharacters in parameters
- System logs showing unexpected command execution from web server user
Network Indicators:
- HTTP requests to export.php with suspicious filename parameters containing ;, |, &, `, $, or ()
- Outbound connections from FOG server to unexpected destinations
SIEM Query:
source="web_access.log" AND uri_path="/fog/management/export.php" AND (filename="*;*" OR filename="*|*" OR filename="*`*" OR filename="*$(*)")🔗 References
