CVE-2016-2283
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 ioLogik E2200 devices before 3.12 and ioAdmin Configuration Utility before 3.18 do not properly encrypt data, which makes it easier for remote attackers to obtain the associated cleartext 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 · moderate confidenceMoxa ioLogik E2200 devices before version 3.12 and ioAdmin Configuration Utility before version 3.18 use improper encryption mechanisms, allowing remote attackers to recover cleartext data through unspecified vectors. This represents a cryptographic implementation weakness in both the embedded device firmware and the configuration utility software.

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 the ioLogik device modelAccess the device web interface or check SNMP/sysinfo to confirm the exact model number is ioLogik E2200 seriesAffected if The device is a Moxa ioLogik E2200 series
-
Check ioLogik firmware versionLog into the device web interface and navigate to System > Firmware Version, or use the ioAdmin utility to query the device firmware versionAffected if Firmware version is 3.11 or earlier
-
Check ioAdmin utility versionOn the management workstation, open ioAdmin Configuration Utility and go to Help > About to view the installed software versionAffected if ioAdmin version is 3.17 or earlier
-
Verify data-in-transit protectionCapture network traffic between the ioAdmin utility and the device using a packet sniffer, then inspect whether sensitive configuration data is transmitted in cleartext or uses weak/obfuscated encryptionAffected if Configuration data is transmitted without proper encryption or uses easily reversible obfuscation
You are affected if you have a Moxa ioLogik E2200 device running firmware 3.11 or earlier, or use ioAdmin Configuration Utility version 3.17 or earlier, especially if sensitive data is transmitted over the network without strong encryption.
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 dataUpgrade ioLogik E2200 devices to firmware version 3.12 or later and ioAdmin Configuration Utility to version 3.18 or later to implement proper encryption. If immediate patching is not feasible, restrict network access to these devices and monitor for unauthorized access attempts.
