🔧 Temporary Workarounds
Network Access Restriction
linuxRestrict network access to Bastillion management interface to trusted IP addresses only.
iptables -A INPUT -p tcp --dport [bastillion_port] -s [trusted_ip] -j ACCEPT
iptables -A INPUT -p tcp --dport [bastillion_port] -j DROP
Disable System Management Module
allTemporarily disable or restrict access to the vulnerable System Management Module if not required.
🧯 If You Can't Patch
- Implement strict network segmentation to isolate Bastillion from critical systems
- Deploy web application firewall (WAF) with command injection rules and monitor for exploitation attempts
