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
Fileszie Check vulnerabilities allow a malicious user to bypass size limits or overload to the product.  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 vulnerability in ABB ASPECT, NEXUS, and MATRIX Series products allows malicious users to bypass filesize checks, potentially enabling denial of service through resource exhaustion or bypassing configured size limits. The CVSS 7.5 indicates network-exploitable, low-complexity attacks that could overload the system.

MitigationImplement proper filesize validation on all file upload and processing operations, and apply vendor-provided patches for version 3.08.02. Network segmentation and access controls may help limit exposure until patches are applied.

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 device model and firmware version
    Access the ABB device web interface or use SNMP/sysinfo commands to retrieve the exact model number and current firmware version
    Affected if Model is ABB ASPECT Ent 2/256/96, Nexus 2128/2128 A/F/G, or Nexus 264 with firmware version below 3.08.03
  2. Confirm file upload or processing feature is enabled
    Check the device configuration or web interface for file upload, file transfer, data import, or firmware update features that accept file input
    Affected if Any file upload or file processing functionality is enabled and accessible to users or processes
  3. Verify file size limit configuration
    Inspect the device configuration settings for any configured file size restrictions, upload limits, or quota settings
    Affected if File size limits are configured (the vulnerability allows bypassing these limits)

The environment is affected if it contains an ABB ASPECT or Nexus device with firmware version below 3.08.03 that has file upload or processing features enabled and potentially file size restrictions configured.

Generated from the published advisory. Verify against your own configuration.

Check your environment

Paste your version and any relevant configuration and it will be compared against the affected criteria above. Do not include secrets or credentials.

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

Implement proper filesize validation on all file upload and processing operations, and apply vendor-provided patches for version 3.08.02. Network segmentation and access controls may help limit exposure until patches are applied.

Recommended fix High confidence

Firmware version 3.08.03 for all affected products (Aspect Enterprise 2/256/96, Nexus 2128/2128A/2128F/2128G, Nexus 264)

  1. 1. Identify the current firmware version of the affected device by accessing the device management interface or checking system information.
  2. 2. Download the fixed firmware version 3.08.03 from the official ABB support portal at search.abb.com or authorized ABB distribution channels.
  3. 3. Review the ABB firmware upgrade documentation for your specific model (Aspect Enterprise or Nexus Series) before proceeding.
  4. 4. Back up the current device configuration according to ABB best practices to preserve settings.
  5. 5. Upload the firmware version 3.08.03 to the device using the manufacturer's recommended upgrade procedure (typically via web interface, CLI, or dedicated upgrade tool).
  6. 6. After the upgrade completes, verify the device is running firmware version 3.08.03.
  7. 7. Confirm that the previously vulnerable file size check functionality now properly enforces limits.
Caveat Firmware upgrades may temporarily interrupt device operation; review release notes for any configuration or compatibility changes before upgrading
