Default FTP Credentials (ntpupdate / ntpupdate)

critical Nessus Plugin ID 73188


The remote FTP server can be accessed with default credentials.


It is possible to log into the remote FTP server by providing default credentials. A remote attacker could exploit this to gain access to the remote server.

These credentials are known to apply to Schneider Electric Modicon M340 for Ethernet devices; however, they may apply to other FTP services as well.


Change the default password or block access to the port.
