Doc Text:
The Windows installer for EnterpriseDB-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, this allows a local attacker to read arbitrary data directory files, essentially bypassing database-imposed read access limitations. In plausible non-default configurations, an attacker having both an unprivileged Windows account and an unprivileged PostgreSQL account can cause the PostgreSQL service account to execute arbitrary code.

Description Pedro Sampaio 2019-05-06 19:53:19 UTC 
The Windows installer for EnterpriseDB-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, this allows a local
attacker to read arbitrary data directory files, essentially bypassing
database-imposed read access limitations. In plausible non-default
configurations, an attacker having both an unprivileged Windows account and an
unprivileged PostgreSQL account can cause the PostgreSQL service account to
execute arbitrary code.
