CVE-2024-51545
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 · uneditedUsername Enumeration vulnerabilities allow access to application level username add, delete, modify and list functions. 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 · high confidenceUsername enumeration vulnerability in ABB industrial control products (ASPECT Enterprise, NEXUS Series, MATRIX Series v3.08.02) allows unauthenticated attackers to enumerate valid usernames and then access application-level user management functions including adding, deleting, modifying, and listing user accounts.

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 installed ABB product modelLocate the physical device label or check the system documentation to confirm the exact ABB model (Aspect Enterprise variant or Nexus Series variant)Affected if The model is an ABB Aspect Enterprise (12, 2, 256, or 96) or ABB Nexus (2128, 2128 A, 2128 F, or 2128 G)
-
Check the firmware versionAccess the device admin interface or use the vendor's management software to view the current firmware version. Compare against 3.08.03Affected if The firmware version is lower than 3.08.03 (for example, 3.08.02 or earlier)
-
Verify network exposure of the user management interfaceDetermine if the web-based user management or application interfaces are reachable from network segments accessible to untrusted users. Check firewall rules and access control lists around the ICS environmentAffected if The user management interface is accessible from outside the protected ICS network without authentication restrictions
You are affected if you have an ABB Aspect Enterprise or Nexus Series device running firmware below version 3.08.03 with the management interface exposed to network segments where untrusted users could attempt username enumeration.
Generated from the published advisory. Verify against your own configuration.
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-supplied patch from ABB for version 3.08.02; implement network segmentation to limit exposure of the affected industrial control system interfaces.
Firmware version 3.08.03 (or later if available)
- 1. Identify the specific ABB product model (Aspect Ent 12, Aspect Ent 2, Aspect Ent 256, Aspect Ent 96, Nexus 2128, Nexus 2128 A, Nexus 2128 F, or Nexus 2128 G) from the affected devices
- 2. Access the device management interface through the web console or dedicated management tool
- 3. Check the current firmware version to confirm it is below 3.08.03
- 4. Download firmware version 3.08.03 or later from ABB's official support portal at search.abb.com
- 5. Follow ABB's standard firmware upgrade procedure for the specific device model (typically via web interface upload or dedicated update utility)
- 6. After upgrade, verify the new firmware version is 3.08.03 or higher
- 7. Test that username enumeration vulnerabilities are no longer present
