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 · unedited
Unauthorized Access vulnerabilities allow Remote Code Execution.  Affected products: ABB ASPECT - Enterprise v3.08.02; NEXUS Series v3.08.02; MATRIX Series v3.08.02

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 · moderate confidence

This is a critical unauthenticated remote code execution vulnerability in ABB's industrial control system software (ASPECT Enterprise) and hardware series (NEXUS, MATRIX). The vulnerability allows unauthorized attackers to bypass access controls and execute arbitrary code on affected systems, likely through the web interface or API components.

MitigationApply vendor-supplied patches or updates for version 3.08.02 when available; until then, isolate affected systems on dedicated network segments, disable unnecessary external access, and monitor for indicators of compromise.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify the ABB product model
    Locate the physical device label or access the device's system information page to determine if the unit is an ASPECT Enterprise (Ent 2, Ent 256, Ent 96) or NEXUS series (2128, 2128 A/F/G, 264)
    Affected if The device is any of the listed ABB models (ASPECT Enterprise or NEXUS series)
  2. Check the installed firmware version
    Access the device's administrative interface or check the system diagnostics page to retrieve the current firmware version number
    Affected if The firmware version is lower than 3.08.03 (for example, 3.07.x, 3.06.x, or earlier)
  3. Determine if the web interface is enabled
    Check the device configuration settings for web server or HTTP API status; verify if ports 80/443 or custom web service ports are listed as active
    Affected if The web interface or HTTP/HTTPS API is enabled and accessible on the network
  4. Verify external exposure of the web service
    Review network firewall rules and port mappings to determine if the device's web interface is reachable from external networks or the internet
    Affected if The web interface is exposed directly to untrusted networks or the internet without network isolation

A user is affected if they have an ABB ASPECT Enterprise or NEXUS device running firmware version below 3.08.03 with the web interface or API enabled and 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 · scoped
Upgrade available Upgrade to 3.08.03 or later
Fixed in 3.08.03
Interim mitigation

Apply vendor-supplied patches or updates for version 3.08.02 when available; until then, isolate affected systems on dedicated network segments, disable unnecessary external access, and monitor for indicators of compromise.

Recommended fix Moderate confidence

Firmware version 3.08.03 or later for all affected ABB Aspect Enterprise and Nexus Series devices

  1. Identify the specific ABB device model (Aspect Ent 2/96/256 or Nexus 2128/2128A/2128F/2128G/264) in your environment
  2. Access the device firmware management interface or use ABB's official firmware update process
  3. Download the firmware version 3.08.03 or later from ABB's official support portal (search.abb.com)
  4. Verify the firmware integrity using checksums provided by ABB
  5. Apply the firmware upgrade following ABB's documented upgrade procedure for the specific device model
  6. After upgrade, verify the device is operational and consider network segmentation to limit exposure until patching is complete
Caveat Review ABB release notes for version 3.08.03 to check for any configuration or compatibility changes before upgrading production systems
