CVE-2020-7003
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 · uneditedIn Moxa ioLogik 2500 series firmware, Version 3.0 or lower, and IOxpress configuration utility, Version 2.3.0 or lower, sensitive information is transmitted over some web applications in clear text.
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 ioLogik 2500 series firmware (v3.0 and below) and IOxpress configuration utility (v2.3.0 and below) transmit sensitive information in cleartext over certain web applications, allowing network interceptors to capture potentially confidential data.

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 model and firmware versionAccess the device web interface and navigate to System Settings > Firmware Information, or use the IOxpress utility to query the device for its current firmware versionAffected if Firmware version is 3.0 or below on any ioLogik 2512 variant (2512, 2512 T, 2512 HSPA, 2512 HSPA T, 2512 WL1 EU, 2512 WL1 EU T, 2512 WL1 US, 2512 WL1 US T)
-
Confirm HTTP web service is enabledAccess the device web interface and check Network Settings > Web Server. Look for HTTP (port 80) being enabled alongside or instead of HTTPS (port 443)Affected if HTTP service is enabled on the device and accessible over the network
-
Verify if sensitive operations traverse HTTPUse a network packet capture tool (such as Wireshark or tcpdump) on the network segment between the device and a client. Perform actions such as login, configuration changes, or data retrieval and observe whether credentials or configuration data are transmitted in cleartext over HTTPAffected if Network capture shows username, password, configuration data, or other sensitive information sent in cleartext over HTTP rather than encrypted HTTPS
-
Check IOxpress utility version if usedOn the workstation running IOxpress, open the application and check Help > About for the software versionAffected if IOxpress configuration utility version is 2.3.0 or below and communicates with the device over an unencrypted channel
The environment is affected if any ioLogik 2512 model runs firmware version 3.0 or below with HTTP enabled and sensitive data is transmitted in cleartext over the network.

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 dataEnable HTTPS/TLS encryption for all web communications on affected devices and upgrade to patched firmware/software versions when available.
