CVE-2025-29660Public exploitNetwork attack vector

Unauthenticated root execution via path traversal

Published Apr 21, 2025 · Updated Apr 21, 2025

Path traversal in the Yi IOT XY-3820 6.0.24.10 daemon allows remote attackers to execute device programs as root via TCP port 6789. The service accepts a relative path such as ../../../usr/bin/cmd and launches the resolved binary without confining resolution to an allowed directory. No authentication or user interaction is required; launching cmd opens port 999 for root-level Bash commands, enabling full device control.
