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

Denial of Service vulnerability in ABB ASPECT Enterprise, NEXUS Series, and MATRIX Series v3.08.02 allows attackers to potentially disrupt device services, likely through malformed requests causing service unavailability. The high CVSS score indicates network-exploitable DoS that could impact industrial operations.

MitigationApply vendor-supplied firmware updates when available; implement network segmentation to isolate ICS devices from untrusted networks; monitor for anomalous traffic patterns and implement rate limiting; contact ABB for specific patch timeline and any available workarounds.

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 device model
    Check the device label, web interface, or system information page to determine if the device is an ASPECT Enterprise or NEXUS Series model (such as Aspect Ent 2, 96, 256 or Nexus 2128, 264, etc.)
    Affected if The device is an ABB ASPECT Enterprise or NEXUS Series model listed in the affected products
  2. Check the installed firmware version
    Access the device web interface, administrative console, or use the vendor-provided diagnostic tool to retrieve the current firmware version
    Affected if The firmware version is lower than 3.08.03 (for example, 3.08.02 or earlier)
  3. Verify network exposure of the device
    Review network configuration to determine if the device management interface is directly accessible from untrusted networks or the internet
    Affected if The device is reachable from network segments that contain untrusted or external systems
  4. Monitor for service availability issues
    Check device logs, ping responsiveness, and web interface availability to identify intermittent connectivity or service disruptions
    Affected if The device exhibits unexplained service unavailability or repeated restarts

The environment is affected if an ABB ASPECT Enterprise or NEXUS Series device is running firmware version 3.08.02 or earlier and is network-accessible to potential attackers.

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

Apply vendor-supplied firmware updates when available; implement network segmentation to isolate ICS devices from untrusted networks; monitor for anomalous traffic patterns and implement rate limiting; contact ABB for specific patch timeline and any available workarounds.

Recommended fix Moderate confidence

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

  1. Verify the current firmware version on the affected device before upgrading
  2. Download the firmware version 3.08.03 or later from the official ABB support portal at search.abb.com
  3. Review all pre-upgrade requirements in the ABB firmware release documentation
  4. Create a backup of the current device configuration if supported
  5. Establish a console or out-of-band management connection for the upgrade process
  6. Upload the firmware file to the device following ABB's standard firmware update procedures
  7. Verify the upgrade was successful by checking the new firmware version
  8. Restart the device if required by the upgrade process
Caveat Review ABB release notes for version 3.08.03 to confirm no configuration or compatibility changes affect your specific deployment
