CVE-2026-38708Network attack vector

Root command execution via unsanitized NTP parameters

Published Jul 31, 2026 · Updated Jul 31, 2026

OS command injection in Cudy router firmware allows remote attackers to execute commands as root through the NTP service. The system.setclock interface passes insufficiently validated and sanitized NTP parameters into system-level command execution. NTP must be enabled; the CVE record names nine firmware builds, while Cudy identifies TR3000 1.0, so public applicability records conflict.
