ABB AWIN Gateways: High-Risk Authentication Flaws Updates
🔒 CISA published an advisory on 2026-04-30 describing multiple authentication-related vulnerabilities in ABB AWIN Gateways that permit unauthenticated queries to disclose system configuration and, in one case, remotely reboot devices. The issues include an authentication bypass via capture-replay and missing authentication for critical functions. Affected firmware includes AWIN GW100 rev.2 (2.0-0, 2.0-1) and AWIN GW120 (1.2-0, 1.2-1); ABB released fixes (FW 2.1-0 and FW 2.0-0, Product IDs 3BNP102988R1 and 3BNP103003R1) and PSIRT advisory 4JNO000329. CISA recommends isolating devices, removing internet exposure, using secure remote access (for example, up‑to‑date VPNs), and conducting impact analysis before deploying mitigations.
