DescriptionKiteworks Core before version 9.5.0 is vulnerable to Arbitrary File Write. An improper restriction of a user-supplied file path in a Kiteworks administrative export feature could allow an authenticated administrator to write a file to an arbitrary location on the underlying host, potentially leading to command execution on the appliance. Exploitation requires an existing, authenticated administrative account with access to the affected export function.
