CVE-2025-53842

Command execution via hard-coded login credentials

Published Jul 16, 2025 · Updated Jul 18, 2025

Hard-coded credentials in ZEXELON ZWX-2000CSW2-HN before 0.3.19 and ZWX-2000CS2-HN all versions allow attackers to execute commands. The device login accepts credentials embedded in firmware, exposing command execution and configuration controls after authentication. An attacker must reach the appliance on an adjacent network and use a high-privilege account; exploitation permits command execution and settings changes.
