A directory traversal within the ‘ftpservlet’ of the FileCatalyst Workflow Web Portal allows files to be uploaded outside of the intended ‘uploadtemp’ directory with a specially crafted POST request. In situations where a file is successfully uploaded to web portal’s DocumentRoot, specially crafted JSP files could be used to execute code, including web shells.
Solution:
The web application does not sufficiently verify inputs that are assumed to be immutable but are actually externally controllable, such as hidden form fields.
The product exposes a resource to the wrong control sphere, providing unintended actors with inappropriate access to the resource.
