Summary
CVE-2025-13777 is a high-severity Authentication Bypass by Capture-replay (CWE-294) vulnerability in Abb (inferred from references). Its CVSS base score is 7.2 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Network Sniffing (T1040); ranked at the 13th 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 SC-23 (Session Authenticity) 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-2025-13777 is an authentication bypass vulnerability stemming from a capture-replay issue, mapped to CWE-294. It affects 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. The vulnerability was published on 2026-03-13.
The CVSS v3.1 base score is 8.3 (High), with attack vector AV:A (adjacent network), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and unchanged scope (S:U), resulting in high confidentiality (C:H) and availability (A:H) impacts, plus low integrity (I:L) impact. An adjacent attacker can capture and replay authentication traffic to bypass controls without prior authentication.

Mitigating Controls (NIST 800-53 r5) AI
Session authenticity mechanisms directly stop replay of captured authentication traffic by enforcing freshness or cryptographic binding.
Transmission integrity (with anti-replay) stops captured messages from being accepted as valid later.
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.
Protecting and verifying identity assertions prevents replay of captured authentication material.
Encryption and integrity protections for data-in-transit directly block capture-replay of credentials or tokens.
Network monitoring may detect anomalous replays after the fact but does not prevent the design flaw.
Strong authentication methods can reduce replay risk but do not inherently address captured messages.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Cryptographic protections (e.g., nonces, timestamps, message authentication codes) make captured authentication messages unusable for replay.
Secure authentication mechanisms directly prevent replay attacks by requiring fresh, non-replayable credentials or tokens.
Network security controls such as encryption and integrity protection reduce the feasibility of capturing and replaying authentication traffic.
Application security requirements can mandate replay-resistant authentication designs, but the control itself does not prescribe the technical measures.
