Summary

CVE-2025-13779 is a high-severity Missing Authentication for Critical Function (CWE-306) vulnerability in Abb (inferred from references). Its CVSS base score is 7.2 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique External Remote Services (T1133); ranked at the 21th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to AC-14 (Permitted Actions Without Identification or Authentication) and IA-2 (Identification and Authentication (Organizational Users)) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2025-13779 is a missing authentication for critical function vulnerability, classified under CWE-306, affecting ABB AWIN GW100 rev.2 firmware versions 2.0-0 and 2.0-1, as well as ABB AWIN GW120 firmware versions 1.2-0 and 1.2-1. Published on 2026-03-13, it carries a CVSS v3.1 base score of 8.3 (AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:H), indicating high severity due to significant impacts on confidentiality and availability.

An attacker on an adjacent network can exploit this vulnerability with low complexity and no required privileges or user interaction. Exploitation grants high confidentiality and availability impacts, alongside low integrity impact, potentially allowing unauthorized access to critical functions, data exposure, service disruption, and limited modification of system resources.

Mitigation guidance is available in the official ABB security advisory at https://search.abb.com/library/Download.aspx?DocumentID=4JNO000329&LanguageCode=en&DocumentPartId=&Action=Launch. Security practitioners should consult this reference for patching instructions and workarounds specific to the affected devices.

Mitigating Controls (NIST 800-53 r5) AI

Directly mandates unique identification and authentication of users before access to functions requiring identity.

Extends the same authentication requirement to non-organizational users accessing critical functionality.

Requires authentication of services before they can invoke or expose critical functions.

Explicitly identifies and limits actions permitted without authentication, preventing critical functions from being exposed.

Access enforcement requires prior authentication before any authorization decision for critical functions.

PR.AA-03 full match
blocks

Directly requires authentication of users/services/hardware, which eliminates missing authentication for critical functions.

PR.AA-01 partial match
blocks

Managing identities and credentials is a prerequisite for authentication but does not itself enforce it on critical functions.

PR.AA-05 partial match
blocks

Defining and enforcing authorizations assumes prior authentication and therefore only partially mitigates the absence of authentication.

PR.IR-01 partial match
blocks

Protecting networks from unauthorized access can be undermined by missing authentication but does not address the root authentication gap.

blocks

A.8.5 mandates choosing and enforcing appropriate strong/multi-factor authentication techniques (with anti-brute-force, session, and log-on protections) that directly stop exploitation of missing auth on critical functions; the bounded remainder is non-interactive critical functions (e.g. unauthenticated APIs or resources) outside its user/entity authentication focus.
