Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-2 Flaw Remediation good match

prevent

Directly addresses the CVE by requiring identification, reporting, and timely remediation of the specific software flaw in the authentication algorithm implementation via vendor patches.

IA-5 Authenticator Management partial match

prevent

Ensures proper management of authenticators including selection and lifecycle of secure mechanisms to mitigate risks from incorrect authentication algorithms.

SC-13 Cryptographic Protection partial match

prevent

Mandates use of NIST-approved cryptographic modules and algorithms for authentication protections, preventing exploitation of flawed implementations.

NVD Description

Incorrect Implementation of Authentication Algorithm vulnerability in ABB ABB Ability OPTIMAX.This issue affects ABB Ability OPTIMAX: 6.1, 6.2, from 6.3.0 before 6.3.1-251120, from 6.4.0 before 6.4.1-251120.

Deeper analysisAI

CVE-2025-14510, published on 2026-01-16, is an Incorrect Implementation of Authentication Algorithm vulnerability (CWE-303) in ABB Ability OPTIMAX. The issue affects versions 6.1 and 6.2, as well as versions from 6.3.0 before 6.3.1-251120 and from 6.4.0 before 6.4.1-251120. It carries a CVSS v3.1 base score of 8.1 (AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H), indicating high severity due to substantial impacts on confidentiality, integrity, and availability.

Attackers with network access can exploit this vulnerability without authentication privileges or user interaction, though it requires high attack complexity. Successful exploitation enables high-impact disruption, including unauthorized access to sensitive data, modification of system integrity, and denial of service affecting availability, all within the unchanged scope of the affected component.

ABB provides further details and mitigation guidance in its security advisory at https://search.abb.com/library/Download.aspx?DocumentID=9AKK108472A1331&LanguageCode=en&DocumentPartId=&Action=Launch, which aligns with upgrading to patched releases such as 6.3.1-251120 and 6.4.1-251120.
