CVE-2024-11667Zyxel gateways — path traversal moves files through the console

The web management interface of the affected Zyxel gateway firmware (ATP, USG FLEX, USG20-VPN) lets a crafted address download or upload files outside the intended directory.

YOUR NEXT MOVE

Update to firmware past V5.38 now; ransomware crews use this, so review administrator accounts and any file the console could have written.
