By exploiting the way Apache OpenOffice before 4.1.4 renders embedded objects, an attacker could craft a document that allows reading in a file from the users filesystem. Information could be retrieved by the attacker by, e.g., using hidden sections to store the information, tricking the user into saving the document and convincing the user to send the document back to the attacker. The vulnerability is mitigated by the need for the attacker to know the precise file path in the target system, and the need to trick the user into saving the document and sending it back.
The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.

There are many different kinds of mistakes that introduce information exposures. The severity of the error can range widely, depending on the context in which the product operates, the type of sensitive information that is revealed, and the benefits it may provide to an attacker. Some kinds of sensitive information include:
Information might be sensitive to different parties, each of which may have their own expectations for whether the information should be protected. These parties include:
Information exposures can occur in different ways:
It is common practice to describe any loss of confidentiality as an “information exposure,” but this can lead to overuse of CWE-200 in CWE mapping. From the CWE perspective, loss of confidentiality is a technical impact that can arise from dozens of different weaknesses, such as insecure file permissions or out-of-bounds read. CWE-200 and its lower-level descendants are intended to cover the mistakes that occur in behaviors that explicitly manage, store, transfer, or cleanse sensitive information.
