Description

The Windows installer for PostgreSQL 9.5 - 12 invokes system-provided executables that do not have fully-qualified paths. Executables in the directory where the installer loads or the current working directory take precedence over the intended executables. An attacker having permission to add files into one of those directories can use this to execute arbitrary code with the installer's administrative rights.

Affected products

• PostgreSQL: from 9.5 before 9.5.22; from 9.6 before 9.6.18; from 10.0 before 10.13; from 11.0 before 11.8; from 12.0 before 12.3 — fixed in 10.13, 11.8, 12.3, 9.5.22, 9.6.18

How to fix

Upgrade to a fixed version: PostgreSQL 10.13, 11.8, 12.3, 9.5.22. Check the vendor advisory for mitigations.
