CVE-2023-0635
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.

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 confidenceImproper privilege management in ABB ASPECT-Enterprise, NEXUS Series, and MATRIX Series industrial control software allows authenticated attackers to escalate privileges to administrative levels. This vulnerability affects versions 3.0 through 3.07.00 across all three product lines, enabling potential full system compromise.

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 ABB product modelLocate the system documentation, HMI interface, or check the device label to determine if the product is one of: ASPECT-Enterprise (models 2, 12, 96, 256), NEXUS Series (2128, 2128 A, 2128 G, 2128 F), or MATRIX SeriesAffected if The device is any of these ABB product lines
-
Retrieve the installed firmware versionAccess the device admin panel, system information screen, or use the device's web interface to view the firmware version. The exact method varies by product but is typically found under Settings, System Info, or About sectionsAffected if Unable to determine the version (unverified product status)
-
Compare version against affected rangeCheck if the installed version is >= 3.0.0 and < 3.07.01. Versions 3.0.0 through 3.07.00 are all affectedAffected if The installed version falls within >= 3.0.0 and < 3.07.01
A user is affected if they are running ABB ASPECT-Enterprise, NEXUS Series, or MATRIX Series firmware versions 3.0.0 through 3.07.00 (versions below 3.07.01).

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 · scoped3.07.01
Upgrade to version 3.07.01 or later to remediate this privilege escalation vulnerability. For production environments, develop a change management plan and test the upgrade in a staging environment before deployment.
Firmware version 3.07.01 or later for Aspect Enterprise, Nexus Series, and MATRIX Series
- 1. Identify the specific ABB device model (Aspect Enterprise or Nexus Series) and current firmware version using the device interface or administrative console.
- 2. Navigate to the ABB software download portal at search.abb.com or contact ABB Technical Support to obtain firmware version 3.07.01 or later.
- 3. Review ABB's official firmware upgrade documentation for your specific device model before proceeding.
- 4. Create a full backup of the current device configuration according to ABB's backup procedures.
- 5. Ensure the upgrade process has a stable power supply and network connection to prevent interruption.
- 6. Upload and apply firmware version 3.07.01 or later using the device's firmware update functionality.
- 7. After the firmware upgrade completes, verify the new firmware version is correctly installed.
- 8. Restore the device configuration from the backup taken in step 4.
