Vulnerability details
The vulnerability allows a remote attacker to gain full DBA access to MariaDB and read or write arbitrary files as the mysql operating-system user.
The vulnerability exists due to use of hard-coded credentials in distrib/docker/env_setup_netatalk.sh when the MySQL CNID backend is selected and AFP_CNID_SQL_PASS is unset. A remote attacker can authenticate with the publicly known fallback credential to gain full DBA access to MariaDB and read or write arbitrary files as the mysql operating-system user.
The issue is exposed in deployments using the shipped host-networked compose configuration, and user interaction is required.
