Discussion

Apache Double-Reverse Lookup Log Entry Spoofing Vulnerability

Apache is a freely available webserver for Unix and Linux variants, as well as Microsoft operating systems.

Under some circumstances, Apache may log invalid hostname information. If a double-reverse DNS lookup is performed but fails, then an invalid hostname may appear in the logs. For example, this may occur if the hostname does not properly resolve to the IP address in the double-reverse DNS lookup.

A remote attacker may deliberately exploit this issue to cause spoofed information to be logged by the webserver.
