CVE-2024-51547Network attack vector

Unauthenticated device access via plaintext firmware credentials

Published Feb 6, 2025 · Updated May 23, 2025

Hard-coded credentials in ABB ASPECT firmware through 3.* allow remote attackers to access ASPECT-Enterprise, NEXUS, and MATRIX devices. The firmware stores several credentials used internally by the products as plaintext, permitting their recovery and reuse against device services. Reachability requires access to the ASPECT network segment; ABB states that conforming deployments are not exposed directly to the internet.
