Descriptions

In some configurations an attacker can inject a new executable path into the extensions.load file for osquery and hard link a parent folder of a malicious binary to a folder with known 'safe' permissions. Under those circumstances osquery will load said malicious executable with SYSTEM permissions. The solution is to migrate installations to the 'Program Files' directory on Windows which restricts unprivileged write access. This issue affects osquery prior to v3.4.0.

En algunas configuraciones, un atacante puede inyectar una nueva ruta ejecutable en el archivo extensions.load para osquery y vincular una carpeta principal de un binario malicioso a una carpeta con permisos "seguros" conocidos. En esas circunstancias, osquery cargará dicho ejecutable malicioso con permisos de SISTEMA. La solución es migrar las instalaciones al directorio 'Archivos de programa' en Windows, que restringe el acceso de escritura sin privilegios. Este problema afecta a osquery antes de v3.4.0.
