CVE-2020-11081 Information

Description

osquery before version 4.4.0 enables a privilege escalation vulnerability. If a Window system is configured with a PATH that contains a user-writable directory then a local user may write a zlib1.dll DLL which osquery will attempt to load. Since osquery runs with elevated privileges this enables local escalation. This is fixed in version 4.4.0.
