Last modified
CVE-2019-3567 is a vulnerability of currently unknown severity. 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. EPSS estimates a 1.66% chance of exploitation in the next 30 days.
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.
