CVE-2023-31240Network attack vector

Authentication bypass via hard-coded superuser credentials

Published May 22, 2023 · Updated Jan 16, 2025

Authentication bypass in Snap One OvrC Pro before 7.2 allows remote attackers to access hub web servers with hard-coded credentials. A built-in hidden Superuser account on the hub web server accepts credentials embedded in the product through both local-network and cloud access paths. No prior account is required; the flaw grants privileged web access, while arbitrary command execution depends on separate vulnerable functionality.
