Synology DiskStation Manager uistrings.cgi lang Parameter Directory Traversal

This script is Copyright (C) 2014-2016 Tenable Network Security, Inc.

Synopsis :

The remote Synology DiskStation Manager is affected by a directory
traversal vulnerability.

Description :

The Synology DiskStation Manager installed on the remote host is
affected by a directory traversal vulnerability. By sending a large,
padded file path to the 'lang' parameter of the 'uistrings.cgi'
script, an overflow will occur within the snprintf function used to
prevent such attacks. A remote, unauthenticated attacker could
leverage this vulnerability to view lines with an equal sign, notably
key/value pairs, in files.

Note that the affected uistrings.cgi script is located in both the
'/scripts/' and '/webfm/webUI/' web directories.
