CVE-2024-51543
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 · uneditedInformation Disclosure vulnerabilities allow access to application configuration information. 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 confidenceInformation disclosure vulnerability in ABB ASPECT Enterprise, NEXIX Series, and MATRIX Series v3.08.02 allows unauthorized access to application configuration information. The specific attack vector and authentication requirements are not detailed in available sources, but the high CVSS score indicates significant exposure of sensitive configuration data that could aid further attacks.
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 checksWork through these to decide whether this CVE applies to you.
-
Identify the ABB device modelLocate the physical device or check network inventory for ABB ASPECT Enterprise or NEXIX Series controllers. Look for model labels such as Aspect Ent 12, Aspect Ent 2, Aspect Ent 256, Aspect Ent 96, Nexus 2128, Nexus 2128 A, Nexus 2128 F, or Nexus 2128 G.Affected if The device model matches any of the affected product lines (Aspect Enterprise or Nexus 2128 series).
-
Determine the firmware versionAccess the device web interface or console and navigate to the system information or firmware version page. For web interface, typically browse to the device IP and look under 'System', 'About', or 'Firmware Information' sections.Affected if The installed firmware version is lower than 3.08.03 (e.g., 3.08.02, 3.08.01, 3.07.x, etc.).
-
Check if configuration interface is network accessibleVerify whether the device web interface or configuration ports (typically HTTP/HTTPS on port 80/443 or vendor-specific ports) are exposed to the network. Use network scanning or review firewall rules.Affected if The configuration interface is accessible from network segments outside the trusted operational zone, increasing exposure to the information disclosure flaw.
The environment is affected if any ABB ASPECT Enterprise or NEXIX Series device with firmware version below 3.08.03 has its configuration interface network-accessible.

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 · scoped3.08.03
Apply vendor-provided patches or updates to address the information disclosure vulnerability. If no patch is available, restrict network access to these industrial control system devices and monitor for unauthorized access attempts to configuration interfaces.
Firmware version 3.08.03
- 1. Identify the specific ABB device model from the affected products list (Aspect Ent 12, Ent 2, Ent 256, Ent 96, Nexus 2128, Nexus 2128 A, Nexus 2128 F, or Nexus 2128 G)
- 2. Access the device management interface and verify the current firmware version is below 3.08.03
- 3. Obtain the fixed firmware version 3.08.03 from ABB's official support portal at search.abb.com or through your ABB representative
- 4. Follow ABB's standard firmware upgrade procedure for the specific device model, which typically includes backing up configuration, uploading the firmware file, and rebooting the device
- 5. After reboot, verify the firmware has been updated to version 3.08.03 or later
- 6. Confirm the information disclosure vulnerability is remediated by verifying configuration data is no longer accessible without proper authentication
