Descriptions

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.

osquery versiones anteriores a 4.4.0, habilita una vulnerabilidad de escalada de privilegios. Si un sistema Windows está configurado con una PATH que contiene un directorio escribible por parte del usuario, entonces un usuario local puede escribir una biblioteca DLL zlib1.dll, que osquery intentará cargar. Ya que osquery se ejecuta con privilegios elevados, esto permite una escalada local. Esto es corregido en la versión 4.4.0
