Descriptions

A vulnerability was found in postgresql versions 11.x prior to 11.3. The Windows installer for BigSQL-supplied PostgreSQL does not lock down the ACL of the binary installation directory or the ACL of the data directory; it keeps the inherited ACL. In the default configuration, an attacker having both an unprivileged Windows account and an unprivileged PostgreSQL account can cause the PostgreSQL service account to execute arbitrary code. An attacker having only the unprivileged Windows account can read arbitrary data directory files, essentially bypassing database-imposed read access limitations. An attacker having only the unprivileged Windows account can also delete certain data directory files.

Se encontró una vulnerabilidad en postgresql versiones 11.x anteriores a la 11.3. El instalador de Windows para PostgreSQL proporcionado por BigSQL no bloquea la ACL del directorio de instalación binaria ni la ACL del directorio de datos; mantiene la ACL heredada. En la configuración predeterminada, un atacante que tenga tanto una cuenta de Windows sin privilegios como una cuenta de PostgreSQL sin privilegios puede causar que la cuenta de servicio de PostgreSQL ejecute código arbitrario. Un atacante que solo tenga la cuenta de Windows sin privilegios puede leer archivos del directorio de datos arbitrarios, esencialmente omitiendo las limitaciones de acceso de lectura impuestas por la base de datos. Un atacante que solo tenga la cuenta de Windows sin privilegios también puede eliminar determinados archivos del directorio de datos
