Deeper analysis
CVE-2024-51546 is a credentials disclosure vulnerability that permits unauthorized access to onboard project backup bundles. It affects ABB ASPECT Enterprise, NEXUS Series, and MATRIX Series products, all at version 3.08.02. The issue is tracked under CWEs 1287 and 522 and carries a CVSS 4.0 score of 8.7, reflecting network-accessible exposure with no required authentication or user interaction and a primary impact on confidentiality.
An unauthenticated remote attacker can exploit the flaw to retrieve sensitive credentials stored within the backup bundles, potentially enabling further compromise of the affected industrial control or building automation systems. The attack requires no special privileges or user interaction, consistent with the CVSS vector showing high confidentiality impact and limited secondary effects on integrity and availability.
ABB has published an advisory describing the issue and associated remediation steps at https://search.abb.com/library/Download.aspx?DocumentID=9AKK108469A7497&LanguageCode=en&DocumentPartId=&Action=Launch.

Mitigating Controls
Likely Mitigating Controls AI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Training instructs users on protecting credentials from disclosure or unauthorized access.
Training records for security awareness and role-based training verify education on credential protection practices, tangibly reducing risks from mishandling or exposing credentials.
Protecting authenticator content from unauthorized disclosure and modification while requiring protective controls addresses insufficiently protected credentials.
Rules of behavior include credential protection and non-sharing requirements, reducing exposure of insufficiently protected credentials.
Terminating or revoking credentials stops use of insufficiently protected or lingering credentials post-termination.
Requiring confidentiality/integrity protection for stored credentials directly mitigates insufficiently protected credentials on disk or in configuration stores.
Credentials or keys delivered out-of-band are not exposed to interception or inadequate protection on the main transport.
