VisitorBook LE contains a flaw that may allow a malicious user to force it to incorrectly log the source of a request. The issue is triggered because VisitorBook will log a user's reverse DNS entry if it exists, or its IP otherwise. If a user can change or spoof their reverse DNS entry, it will be logged instead of their IP, allowing the user to hide their true identity.
