Description
On a Kiteworks Email Protection Gateway cluster with database replication enabled, a party trusted by the cluster could submit a crafted serialized object that was deserialized without sufficient validation, potentially allowing code execution as the gateway service account. Replication is disabled by default, and exploitation requires control of a trusted cluster peer or administrative access to the appliance.
