Mitigation checklist
- To mitigate this vulnerability, avoid manually configuring and enabling the syslog-ng SQL driver if it is not essential for your environment. If the SQL driver is required, restrict network access to the syslog-ng instance to trusted networks only, for example, by configuring firewall rules to limit connections to the syslog-ng port. Note that changes to network configurations or syslog-ng service settings may require a service reload or restart to take effect, which could temporarily interrupt logging services.
