CVE-2016-2286
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedMoxa MiiNePort_E1_4641 devices with firmware 1.1.10 Build 09120714, MiiNePort_E1_7080 devices with firmware 1.1.10 Build 09120714, MiiNePort_E2_1242 devices with firmware 1.1 Build 10080614, MiiNePort_E2_4561 devices with firmware 1.1 Build 10080614, and MiiNePort E3 devices with firmware 1.0 Build 11071409 have a blank default password, which allows remote attackers to obtain access via unspecified vectors.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceMoxa MiiNePort serial-to-Ethernet device converters ship with blank/empty default administrative passwords across multiple firmware versions (1.0-1.1.10), allowing remote attackers to gain full administrative access via unspecified network vectors.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify device modelAccess the device web interface or console and locate the model information. MiiNePort models include E1 4641, E1 7080, E2 1242, E2 4561, and E3.Affected if The device is any Moxa MiiNePort model (E1 4641, E1 7080, E2 1242, E2 4561, or E3)
-
Check firmware versionIn the device web interface, navigate to the System Settings or Firmware Information section to view the installed firmware version.Affected if The firmware version falls between 1.0 and 1.1.10 inclusive (including 1.0, 1.1, and 1.1.10)
-
Verify admin password statusAttempt to log into the device administrative interface using the username 'admin' with a blank/empty password field. Alternatively, check the user account configuration page to see if the admin account has a password defined.Affected if The admin account has no password set or uses the factory default blank password
-
Confirm remote administrative access is enabledIn the device network settings, check if remote web-based management or telnet/SSH access is enabled on WAN or external interfaces. Look for settings like 'Enable Web', 'Remote Access', or 'Allow remote administration'.Affected if Remote administrative access is enabled and the device is reachable from network segments outside the local administration zone
You are affected if you have a Moxa MiiNePort device (any of the E1/E2/E3 models) running firmware version 1.0 through 1.1.10, with the default admin password still blank or unchanged, and with remote administrative access enabled.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImmediately change all default blank passwords on affected MiiNePort devices, disable remote administrative access if not required, and place devices behind firewalls or in isolated network segments to reduce exposure.
