🔧 Temporary Workarounds
Network Access Restriction
allRestrict access to affected systems to trusted IP addresses only
# Use firewall rules to limit access
# Example: iptables -A INPUT -p tcp --dport 443 -s trusted_network -j ACCEPT
# Example: iptables -A INPUT -p tcp --dport 443 -j DROP
🧯 If You Can't Patch
- Implement strict network segmentation and firewall rules to limit access to affected systems
- Deploy web application firewall (WAF) with rules to block suspicious HTTP request patterns
