Progressive Robot hMailServer versiones 6.0.0 a 6.3.5 contiene una configuración insegura de permisos en el instalador de Windows que permite a usuarios locales autenticados acceder a datos del servidor de correo. Los directorios de datos, registros, base de datos y archivo de configuración hMailServer.INI heredan permisos débiles durante la instalación, exponiendo información sensible de mensajes y configuración en servidores corporativos de LATAM.
Incorrect default permissions in the Windows installer of Progressive Robot hMailServer 6.0.0 through 6.3.5 allow a local authenticated user to read the mail server's data. The installer created the data, log, temp, database and event folders and the hMailServer.INI configuration file with the permissions inherited from the installation folder, by default under Program Files, which give the local Users group read access. Any user who can sign in to the computer could read every stored message, the logs, the built-in database with the accounts' password hashes whenever the service is stopped, and the configuration file, including the database password, which is sealed only with the machine's DPAPI key and can be unsealed by any local account; with an external database that password gives full control of it. The Linux AppImage of 6.3.0 through 6.3.5 likewise created its per-user data folders readable by other local users.
