Vulnerability from cvelistv5
Published

Modified

Severity ?
5.3 (Medium) - CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:C/C:N/I:H/A:N
Summary
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.
