CVE-2024-51546 is a high-severity Improper Validation of Specified Type of Input (CWE-1287) vulnerability in Abb Aspect-Ent-12 Firmware. Its CVSS base score is 8.7 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Unsecured Credentials (T1552); ranked in the top 28% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to SC-28 (Protection of Information at Rest) and SC-8 (Transmission Confidentiality and Integrity) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
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. The EPSS score has remained flat at 0.1707 since disclosure with no material upward trajectory observed.

Mitigating Controls (NIST 800-53 r5) AI
Protection of information at rest requires encryption or equivalent safeguards for stored credentials.
Transmission confidentiality and integrity enforcement stops credentials from being sent in plaintext or without protection.
SI-10 directly requires validation of information inputs, which structurally prevents type-validation failures from being introduced or exploitable.
Authenticator management requires secure generation, storage, and distribution of credentials, directly stopping insecure methods.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Encrypting data-at-rest fully prevents insecure credential storage while only partially satisfying the broader data-protection outcome.
Encrypting data-in-transit fully prevents interception of credentials in motion while only partially satisfying the broader data-protection outcome.
Credential management practices directly reduce insecure storage/transmission but do not guarantee encryption or transport protection.
Protecting identity assertions covers conveyance of credentials but is narrower than full credential lifecycle protection.
Secure SDLC practices directly require proper input type validation during development.
Authentication policies can enforce stronger credential handling yet address only verification, not storage or transit protection.

Requiring protected storage, transmission, and non-display of passwords prevents credentials from being stored or sent in clear text where they can be harvested by unauthorized actors.
Protecting secret and private keys against disclosure and unauthorized use decreases the exposure of credentials that are stored or transmitted in recoverable form.
Security testing can detect type-validation flaws but does not prevent them during development.
Forbidding clear-text transmission and display of passwords, plus the use of stronger alternatives to passwords, prevents credentials from being obtained or reused by attackers.
Acceptable-use expectations that cover protection of credentials and information assets throughout their lifecycle discourage practices that expose or mishandle authentication material.
Contractual clauses that survive termination help ensure that credentials and other secrets are not retained or misused after employment ends.
