CVE-2025-12592Public exploitNetwork attack vector

Remote device takeover via shared default credentials

Published Nov 19, 2025 · Updated Nov 19, 2025

Default credentials in Vivotek legacy device firmware allow remote attackers to access root and user accounts over the network. The firmware hard-codes the shared password mpeg4soc for both login identities instead of requiring a device-specific secret. Remote attackers need only network reachability; the shared root login grants full administrative control of the device.
