Block external access at the network boundary, unless external parties require service. If the service is not required to be globally accessible it is recommended that access be restricted to trusted hosts and networks.
Deploy network intrusion detection systems to monitor network traffic for malicious activity. It is possible that some attacks that result from this vulnerability may be detected by network intrusion detection systems (NIDS). Web servers, application servers and proxy servers also provide various logging facilities that may include indications of attacks. Audit all applicable logs on a regular basis.
Run all software as a nonprivileged user with minimal access rights.
Running the affected server with the least required privileges by forcing it to drop privileges after acquiring system resources is highly recommended. This may greatly reduce the consequences of successful exploitation.
The vendor has released AWStats 6.4 to address this issue.
