DescriptionA privilege escalation vulnerability in Kiteworks could allow an attacker who has already obtained code execution as an unprivileged backend service account on the appliance to escalate to root. A privileged routine did not safely handle a filesystem path that the lower-privileged account could influence, allowing the attacker to cause a root-owned operation to run arbitrary commands with the highest privileges. Exploitation requires existing local access to that service account.
