CVE-2023-22806
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 · uneditedLS ELECTRIC XBC-DN32U with operating system version 01.80 transmits sensitive information in cleartext when communicating over its XGT protocol. This could allow an attacker to gain sensitive information such as user credentials.
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 confidenceThe LS ELECTRIC XBC-DN32U PLC with OS version 01.80 transmits sensitive information including user credentials in cleartext over the XGT protocol. An attacker on the network can intercept these communications to obtain authentication credentials.

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 PLC modelCheck the device model through the XGT programming software (XG5000) or device documentation to confirm the unit is XBC-DN32UAffected if The model is XBC-DN32U
-
Check firmware versionUsing XG5000 software or PLC system information, retrieve the OS firmware version installed on the PLCAffected if The firmware version is exactly 01.80
-
Verify XGT protocol is in useCheck PLC communication configuration in XG5000 under network settings to confirm the XGT protocol is enabled and configured for communicationAffected if XGT protocol is enabled and configured for network communication
-
Check XGT encryption statusInspect the XGT protocol security or encryption settings in the PLC configuration. Look for whether encryption is enforced, disabled, or optional for XGT communicationsAffected if Encryption is disabled or not enforced for XGT protocol communications
You are affected if you have an XBC-DN32U PLC with firmware version 01.80 using the XGT protocol with encryption disabled or not enforced.

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 encryption for XGT protocol communications or upgrade to a firmware version that enforces encrypted communication. Network segmentation should be implemented to restrict unauthorized access to the PLC.
