We haven't been able to figure out why another CVE-2009- ID would be
needed. The year portion of a CVE ID typically refers to when the
vulnerability became publicly known, not (for example) when the
vulnerability was introduced. Before this year, apparently nobody had
disclosed that there was a vulnerability in version 2.2 or later in
which a .php file, but not an arbitrary file, could be downloaded.
Also, the phpMyBackupPro doc/HISTORY.txt doesn't have any entries that
we would consider sufficiently close to a disclosure of that .php
download vulnerability.

So:

  CVE-2009-4050 = original fully-arbitrary file download
                  (the known affected version is 2.1)


  CVE-2015-4180 = download of specific configuration files
                  with a ../../files/filename.php request (the
                  presumed affected versions are at least 2.1 through
                  2.4)

                  (other files with approved extensions can also be
                  downloaded, but this is intentional behavior, not
                  part of the vulnerability)


  CVE-2015-4181 = download of specific configuration files
                  with a ../../files/../files/filename.php request
                  (the presumed affected version are at least 2.1
                  through 2.5)

                  (again, other files with approved extensions can
                  also be downloaded, but this is intentional
                  behavior, not part of the vulnerability)
              

CVE-2015-4181 exists because of an incomplete fix for CVE-2015-4180.
CVE-2015-4180 exists because of an incomplete fix for CVE-2009-4050.
