Mitigation checklist
- Disable the Pgpool-II service if it is not required in your environment: 1. Stop and disable the service: # systemctl stop pgpool # systemctl disable pgpool Alternatively, if the service must remain operational, restrict network access to trusted database clients using firewalld: 2. Allow access only from trusted IP addresses or subnets: # firewall-cmd --permanent --add-rich-rule='rule family="ipv4" source address="<trusted_ip_or_subnet>" port port="9999" protocol="tcp" accept' 3. Ensure general access to the service port is removed: # firewall-cmd --permanent --remove-port=9999/tcp 4. Apply the changes: # firewall-cmd --reload Caveats: Stopping the service disables PostgreSQL connection pooling and load balancing capabilities. Restricting network access with firewall rules will block any legitimate clients connecting from unlisted IP addresses. Warning: Stopping the pgpool service or reloading firewall configurations will disconnect existing client database connections and disrupt service availability until clients reconnect.
