description

hMailServer 6.0.0-B1 through 6.2.18 is affected when it uses MySQL, MariaDB, or PostgreSQL as its database backend. An attacker may alter database queries executed under the mail server database account; authenticated mail submission reaches an affected path by default, while some unauthenticated paths depend on generated responses or optional features.

mitigation

No fixed release is recorded. Where feasible, move affected deployments to SQL Server or SQL Server Compact, and keep greylisting and message indexing disabled; otherwise restrict mail submission to trusted users and limit externally reachable mail services.
