CVE-2019-10128

Local disclosure and code execution via inherited ACLs

Published Mar 19, 2021 · Updated Aug 4, 2024

Improper access control in EDB-supplied PostgreSQL 11.0 through 11.2 on Windows allows local users to read database files. The installer leaves inherited ACLs on the binary installation and data directories instead of restricting them to trusted accounts. A Windows account is enough for file reads; with both an unprivileged Windows account and PostgreSQL account in plausible non-default configurations, attackers can make the service account execute arbitrary code.
