CVE-2020-11081 (GCVE-0-2020-11081)

Vulnerability from cvelistv5 – Published: 2020-07-10 18:45 – Updated: 2024-08-04 11:21

Title

osquery susceptible to DLL search order hijacking of zlib1.dll

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.

Severity

5.3 (Medium)
