ACME Laboratories' Java class Acme.Serve.Serve contains a flaw that allows a remote attacker to traverse outside of the web path. The issue is due to the server not properly sanitizing user input, specifically crafted URI requests using multiple slahses (////). With such a request, an attacker can force the server to access arbitrary files or force a directory index listing.
