🔧 Temporary Workarounds
Network Access Restriction
linuxBlock external access to the vulnerable endpoint using firewall rules.
iptables -A INPUT -p tcp --dport 80 -m string --string "/cgi-bin/luci/admin/openvpn_apply" --algo bm -j DROP
iptables -A INPUT -p tcp --dport 443 -m string --string "/cgi-bin/luci/admin/openvpn_apply" --algo bm -j DROP
Endpoint Disablement
linuxDisable or restrict access to the vulnerable CGI script if possible.
chmod 000 /www/cgi-bin/luci/admin/openvpn_apply
rm /www/cgi-bin/luci/admin/openvpn_apply
🧯 If You Can't Patch
- Isolate affected devices in a dedicated network segment with strict firewall rules
- Implement network monitoring and intrusion detection for exploit attempts
🔍 How to Verify
Check if Vulnerable:
Check if device runs Advantech WISE-6610 version 1.2.1_20251110 and has the /cgi-bin/luci/admin/openvpn_apply endpoint accessible.Check Version:
Check device web interface or console for firmware version informationVerify Fix Applied:
Test if command injection via delete_file parameter is no longer possible after applying workarounds.📡 Detection & Monitoring
