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
Improper Input Validation vulnerability allows 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 an improper input validation vulnerability in ABB ASPECT Enterprise, NEXUS Series, and MATRIX Series SCADA/HMI products version 3.08.02 that allows remote attackers to execute arbitrary code on affected systems due to insufficient validation of user-supplied input.

MitigationApply vendor-provided patches or updates when available; if no patch exists, isolate affected systems on restricted network segments and implement additional input sanitization/filtering as a compensating control.

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 SCADA/HMI product model
    Locate the device label, check the system information screen on the HMI interface, or access the device web interface or management console to identify the exact product model (ASPECT Enterprise variant or NEXUS series)
    Affected if The device is an ABB ASPECT Enterprise (Ent 2, Ent 256, Ent 96) or ABB NEXUS (2128, 2128 A, 2128 F, 2128 G, 264) series device
  2. Determine the installed firmware version
    Access the device through its web interface, management console, or HMI system information screen and record the firmware version number
    Affected if The firmware version is lower than 3.08.03 (for example, 3.08.02, 3.08.01, or earlier)
  3. Verify the device network accessibility
    Check if the SCADA/HMI device has an IP address and is reachable on the network, or review network configuration to determine if it has network services enabled
    Affected if The device is network-accessible and exposes input-handling services to the network (the vulnerability is exploitable remotely via user-supplied input)

A user is affected if they have an ABB ASPECT Enterprise or NEXUS Series SCADA/HMI device running firmware version 3.08.02 or lower that is network-accessible.

Upgrade available Upgrade to 3.08.03 or later
Fixed in 3.08.03
Interim mitigation

Apply vendor-provided patches or updates when available; if no patch exists, isolate affected systems on restricted network segments and implement additional input sanitization/filtering as a compensating control.

Recommended fix High confidence

Firmware version 3.08.03

  1. Identify the specific ABB device model (Aspect Enterprise 2/256/96 or Nexus 2128/2128 A/2128 F/2128 G/264) currently in use
  2. Access ABB's official support portal at search.abb.com and locate the firmware download section
  3. Download firmware version 3.08.03 for the specific device model
  4. Review ABB firmware upgrade documentation for any model-specific instructions
  5. Ensure the device has stable power connectivity before initiating the upgrade
  6. Upload and apply firmware version 3.08.03 through the device's administrative interface
  7. Verify successful installation by checking the firmware version post-upgrade
  8. Confirm all services and functionalities are operational after the upgrade
