CVE-2023-49897 FXC AE1021, AE1021PE: command or code injection

In plain words: The program treats text it receives as instructions instead of plain data. The attacker can run commands on the machine — often the whole device is taken over.

What to do

  1. Install FXC's security update for AE1021, AE1021PE. If no update exists, follow the vendor's workaround or stop using the product until one ships.
  2. Keep a list of every internet-facing server you run so nothing is forgotten.

  4. Put admin and file-transfer apps behind a VPN or single sign-on instead of the open internet.
