A specially constructed URL which may allow undesirable access has been seen. An attempt has been made to access a URL with a trailing %81 thru %fe. Some servers will return the original file, rather than executing it, thus revealing to the potential attacker critical information about the server.

Server source code often contains hidden passwords, hidden filenames, or easy-to-find bugs. The hacker can then use this hidden information to break into the server.
