CVE-2026-38703Network attack vector

Unauthenticated root access via ZeroTier command injection

Published May 28, 2026 · Updated May 28, 2026

Command injection in InHand Networks IR302 3.5.108 and earlier and IR305, IR315, and IR615 1.0.118 and earlier allows remote attackers root access. Public materials identify only the ZeroTier VPN feature; they do not disclose which input enters a command or how neutralization fails. Unauthenticated network access to that feature is sufficient, and injected commands run with root privileges, permitting device takeover or interruption.
