CVE-2016-0878
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 Secure Router EDR-G903 devices before 3.4.12 allow remote attackers to cause a denial of service (cold start) by sending two crafted ping requests.
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 Secure Router EDR-G903 devices before version 3.4.12 contain a vulnerability where sending two crafted ping requests triggers a cold start (complete system reboot), resulting in denial of service. The vulnerability is exploitable remotely without authentication.

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.
-
Confirm device model is EDR-G903Access the device web interface or check the device label/console to verify the exact model number is EDR-G903Affected if Device is not an EDR-G903 model
-
Identify installed firmware versionLog into the device web interface or use the CLI command to display firmware version (typically found in System > Device Information or via 'show version' command)Affected if Firmware version is lower than 3.4.12
-
Verify ping service is enabledCheck device configuration for ICMP/ping response settings under Network or Firewall settingsAffected if Ping responses are allowed from untrusted networks
-
Assess network exposureReview firewall rules or network ACLs to determine if the device management interface is accessible from untrusted networksAffected if Device is directly accessible from the internet or untrusted networks without firewall protection
The environment is affected if the device is an EDR-G903 with firmware version below 3.4.12 and the ping service is accessible from untrusted networks.

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 data3.4.12
Upgrade Moxa EDR-G903 firmware to version 3.4.12 or later. If immediate patching is not feasible, restrict network access to the device's management interfaces using firewalls or ACLs to limit exposure to untrusted networks.
