CVE-2025-8078 is a post-authentication command injection vulnerability affecting multiple Zyxel firewall product lines running vulnerable ZLD firmware, including ATP series, USG FLEX series, USG FLEX 50(W), and USG20(W)-VPN across the specified version ranges. The flaw allows an authenticated administrator to execute operating system commands on the device by supplying a crafted string as an argument to a CLI command. The vulnerability arises from improper neutralization of special elements in command arguments passed from the command-line interface to the underlying operating system, enabling injection of unintended commands.
