CVE-2024-42637Public exploitNetwork attack vector

Root access via hard-coded firmware password

Published Aug 16, 2024 · Updated Aug 16, 2024

Hard-coded credentials in H3C Magic R3010 Firmware 100R002L02 allow remote attackers to log in to the router as root. The affected image embeds a reusable root account credential in /etc/shadow instead of relying solely on a device-specific secret. Network reachability to a login service is required; successful use grants unrestricted administrative control of the router.
