Microsoft Word provides an option to protect “forms” by password. This is used to ensure that unauthorized users cannot manipulate the contents of documents except within specially designed “form” areas. This feature is also often used to protect documents which do not even have form areas (quotations/offers etc.).
This form protection can easily be removed without any additional tools (apart from a hex-editor).
Please find the full advisory attached.
