EPSS: 1.7% probability of exploitation in the next 30 days
Public exploit or detection template: none known
Published: 2019-06-03 · updated 2026-06-17
Weakness: CWE-284

Description

In some configurations an attacker can inject a new executable path into the extensions.load file for osquery and hard link a parent folder of a malicious binary to a folder with known 'safe' permissions. Under those circumstances osquery will load said malicious executable with SYSTEM permissions. The solution is to migrate installations to the 'Program Files' directory on Windows which restricts unprivileged write access. This issue affects osquery prior to v3.4.0.

Affected products

osquery: before 3.4.0 — fixed in 3.4.0

How to fix

Upgrade to a fixed version: osquery 3.4.0. Check the vendor advisory for mitigations.
