CVE-2020-11081

HighCVSS 8.2/10Last modified Jun 17, 2026

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.
