CVE-2022-26117Public exploit

Database access via passwordless MySQL root account

Published Jul 18, 2022 · Updated Oct 25, 2024

Improper password protection in Fortinet FortiNAC affected releases allows local users to access its MySQL databases through the CLI. The appliance configuration leaves the localhost MySQL root account without a password, so mysql -u root opens the database. A low-privileged local shell is required; successful access permits table modification or corruption and retrieval of stored tokens.
