incoming request, VTAdmin validates the actor against the RBAC. As such, the flow of handling the permissions of incoming requests looks as such: Authentication Authentication in VTAdmin has the purpose of claiming to be a user with higher privileges, they are potentially able to elevate their RBAC permissions. Or the user could disguise themselves under the pretence of another user when performing reconnaissance both the reliability of VTAdmin as well as its security posture; If a cluster admin has granted permissions to a user to perform an action against a resource, the user should not be prevented from doing

being only an administrative functionality, a typical example for such functions interacting with the file system would be ExecuteHook. This item was analyzed in depth to see if it is by any means possible traversal and OS-level command injection were attempted for every function that interacted with the file system. Cure53, Berlin · 03/08/19 4/9 Dr.-Ing. Mario Heiderich attempt to execute commands as root. The unachieved goal was to have file system-level capabilities and turn them into direct file manipulation. • After checking all user-exposed endpoints, the application-level
