On Moxa EDS-G508E, EDS-G512E, and EDS-G516E devices (with firmware through 6.0), denial of service can occur via PROFINET DCE-RPC endpoint discovery packets.
An issue was discovered on MOXA EDS-G512E 5.1 build 16072215 devices. An attacker could extract public and private keys from the firmware image available on the MOXA website and could use them against a production switch that has the default keys embedded.
An issue was discovered on MOXA EDS-G512E 5.1 build 16072215 devices. The password encryption method can be retrieved from the firmware. This encryption method is based on a chall value that is sent in cleartext as a POST parameter. An attacker could reverse the password encryption algorithm to retrieve it.
An issue was discovered on MOXA EDS-G512E 5.1 build 16072215 devices. The backup file contains sensitive information in a insecure way. There is no salt for password hashing. Indeed passwords are stored without being ciphered with a timestamped ciphering method.
