CVE-2023-25583Public exploitNetwork attack vector

Command execution via unchecked VLAN interface name

Published Jul 6, 2023 · Updated Nov 4, 2025

OS command injection in Milesight UR32L 32.3.0.5 allows remote authenticated users to execute commands through a crafted VLAN name. The zebra vlan_name function inserts an unchecked interface name into an ip link del shell command and passes the resulting string to system(). Administrative router-console access and creation of a new VLAN are required; injected commands can fully compromise or reboot the appliance.
