CVE-2019-10128: PostgreSQL

High severity, CVSS 7.8. EPSS: 0.4% chance of exploitation in the next 30 days.

A vulnerability was found in postgresql versions 11.x prior to 11.3. 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.

Affected products

• PostgreSQL PostgreSQL: before 9.4.22 (fixed in 9.4.22); from 9.5.0, before 9.5.17 (fixed in 9.5.17); from 9.6.0, before 9.6.13 (fixed in 9.6.13); from 10.0, before 10.8 (fixed in 10.8); from 11.0, before 11.3 (fixed in 11.3)
