Description
CVE-2026-75578 is a command injection vulnerability in Shenzhen Cudy Technology Co., Ltd.'s TR3000 device before version 2.5.42. The flaw exists in the handling of OpenVPN configuration files, where an authenticated administrator can upload a crafted .ovpn file containing malicious shell commands in the remote host token. This allows arbitrary command execution as root due to improper neutralization of special characters in a shell command executed via os.execute().
