Summary
Two Kiteworks Core cluster-management operations did not validate file paths supplied to them, so an attacker holding root on one node of a cluster could write files as root onto another node and cause them to be executed there. Exploitation requires backend root access on a cluster node and a pending software patch present on the target node.
