The remote FTP service is vulnerable to an authentication bypass
According to its self-reported version number, the remote FTP server
is running a version of GridFTP Server earlier than 3.42 / 6.11. Such
versions reportedly are affected by an authentication bypass
vulnerability caused by incorrect use of 'getpwnam_r()'. When a
'gridmap' file is improperly configured with a valid user DN mapped to
a nonexistent user account, the GridFTP server may grant access to the
client under another account.
