CVE-2021-37160
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 · uneditedA firmware validation issue was discovered in HMI3 Control Panel in Swisslog Healthcare Nexus Panel operated by released versions of software before Nexus Software 7.2.5.7. There is no firmware validation (e.g., cryptographic signature validation) during a File Upload for a firmware update.
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 Swisslog Healthcare Nexus Panel's HMI3 Control Panel lacks cryptographic signature validation during firmware updates. An attacker can upload and execute malicious firmware by exploiting the unauthenticated file upload mechanism, as the system does not verify the authenticity or integrity of firmware images before execution.

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 firmware version installed on the HMI3 Control PanelAccess the panel's web interface or administrative console and locate the firmware version information, typically found in the system status, about, or maintenance sectionsAffected if The installed firmware version is lower than 7.2.5.7
-
Verify if firmware signature validation is enabled or presentCheck the panel's security or firmware update configuration settings for any option related to signature verification, code signing, or integrity checksAffected if No signature validation option exists or it is disabled, and the firmware version is below 7.2.5.7
-
Confirm the unauthenticated firmware upload endpoint is accessibleAttempt to access the firmware upload functionality on the panel without authentication, or review access logs for unauthenticated upload requests to the update mechanismAffected if The upload endpoint accepts firmware without requiring authentication and the firmware version is below 7.2.5.7
-
Assess network exposure of the HMI3 Control PanelDetermine if the panel is directly accessible from untrusted networks or the internet by reviewing firewall rules, ACLs, and network segmentationAffected if The panel is exposed to untrusted networks and runs firmware below version 7.2.5.7
You are affected if the HMI3 Control Panel is running firmware version lower than 7.2.5.7 and the unauthenticated firmware upload mechanism is accessible on 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.
dbcve · scoped7.2.5.7
Upgrade to Nexus Software 7.2.5.7 or later which implements firmware signature validation. Until then, restrict network access to the panel and monitor for unauthorized firmware upload attempts.
Nexus Software 7.2.5.7
- Obtain Nexus Software version 7.2.5.7 or later from Swisslog Healthcare's official distribution channel
- Review Swisslog Healthcare's official firmware upgrade documentation for the HMI3 Control Panel
- Apply the firmware update to the Nexus Panel following the vendor's prescribed upgrade procedure
- Confirm the firmware version has been successfully updated to 7.2.5.7 or later
