A vulnerability has been discovered in Kiteworks EPG (Email Security Gateway) that could allow for arbitrary code execution. Kiteworks Email Protection Gateway (EPG) is a cloud-based security solution that automates end-to-end encryption, decryption, and policy enforcement for inbound and outbound enterprise emails. A combination of input-handling flaws in publicly reachable endpoints of the Kiteworks Email Protection Gateway may potentially allow an unauthenticated remote attacker to achieve arbitrary code execution. Successful exploitation of this vulnerability could allow for arbitrary code execution as root, which may lead to the complete compromise of the affected device.
