DescriptionAn optional, separately licensed repository-connector feature in Kiteworks Core did not neutralize special characters in a user-supplied path before passing it to an external command. An authenticated system administrator could inject additional commands and write arbitrary content to files owned by the service account running the connector, enabling code execution in that account's context; exploitation additionally requires network egress from the appliance to a system under the attacker's control.
