Moxa MiiNePort Vulnerabilities

CVSS 9.6 CRITICAL

Remediations

  • Moxa recommends disabling Ports TCP/80 (HTTP) and TCP/23 (TELNET). Moxa indicates that users should ensure that Ports UDP/161 (SNMP), UDP/4800 (utility), and TCP/4900 (utility) are only accessible by trusted systems and that restricting access to Ports UDP/4800 and TCP/4900 will impact remote systems administration.
  • Ensure the passwords have been enabled.
