CVE-2019-6693Fortinet FortiOS — backup encrypted with a built-in key

FortiOS ciphers sensitive values in its configuration backup with a key built into the product, so anyone holding a backup file and that key reads out user passwords and private keys.

YOUR NEXT MOVE

Upgrade FortiOS per Fortinet FG-IR-19-007 now and rotate every credential appearing in an existing backup; treat old backup files as readable.
