CVE-2020-12681
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 · uneditedMissing TLS certificate validation on 3xLogic Infinias eIDC32 devices through 3.4.125 allows an attacker to intercept/control the channel by which door lock policies are applied.
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 3xLogic Infinias eIDC32 door controller devices through version 3.4.125 fail to validate TLS certificates during communication, creating a classic man-in-the-middle (MITM) vulnerability. An attacker on the network can intercept or manipulate the plaintext channel controlling door lock policies, potentially unlocking doors or altering access control rules.

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 Infinias eIDC32Identify whether the physical access control controller on your network is a 3xLogic Infinias eIDC32 door controller. Check device labeling, network inventory, or access the device's web interface or administrative console to verify the model number.Affected if The device is a 3xLogic Infinias eIDC32 door controller
-
Retrieve the installed firmware versionAccess the eIDC32 administrative interface, web console, or use vendor-supplied management software to query the current firmware version installed on the device.Affected if The firmware version cannot be determined or is accessible
-
Compare firmware version against affected rangeTake the installed firmware version and compare it to the affected range: any version less than or equal to 3.4.125 is vulnerable.Affected if The installed firmware version is 3.4.125 or any earlier version
You are affected if your environment contains a 3xLogic Infinias eIDC32 device running firmware version 3.4.125 or lower.

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 dataImplement network segmentation to isolate physical security devices from untrusted networks; contact vendor for patched firmware that implements proper TLS certificate validation; if available, enable certificate pinning in the eIDC32 configuration.
