The host is installed with Apache CouchDB before 1.0.4, 1.1.x before 1.1.2 or 1.2.x before 1.2.1 and is prone to a directory traversal vulnerability. A flaw is present in the application, which fails to handle the partition2 function in mochiweb_util.erl. Successful exploitation could allow remote attackers to read arbitrary files via a ..\ (dot dot backslash) in the default URI.
