CVE-2025-25504Public exploitNetwork attack vector

Root command execution via unauthenticated TCP shell

Published May 5, 2025 · Updated Jul 5, 2026

Command injection in Gefen WebFWC 1.70v, 1.85h, and 1.86v allows remote attackers to execute commands as root over TCP port 4444. The root-run link_mgrc.sh and link_mgrh.sh services invoke jncs.sh, which exposes a command shell without authenticating connecting clients. Network reachability to the device is the only reported gate, and successful access grants full control of the appliance.
