The uploader program in the WebSite web server allows a remote attacker to execute arbitrary programs.
O'Reilly Website Professional 2.5.4 and earlier allows remote attackers to determine the physical path to the root directory via a URL request containing a ":" character.
O'Reilly WebSite Pro 2.3.7 installs the uploader.exe program with execute permissions for all users, which allows remote attackers to create and execute arbitrary files by directly calling uploader.exe.
