A macro is a series of commands and instructions that you group as a single command to complete a task automatically. Microsoft Word supports the use of macros to allow the automation of frequently performed tasks. Because macros are executable code, you can misuse them, so Word has a security model that is designed to validate if a macro should be allowed to run depending on the level of macro security that the user has chosen.
A vulnerability exists because an attacker can craft a malicious document that will bypass the macro security model. If the document was opened, this flaw could permit a malicious macro embedded in the document to be executed automatically, regardless of the level that the macro security is set to. The malicious macro could take the same actions that the user had permissions to carry out such as adding, changing, deleting data or files, communicating with a Web site, or formatting the hard disk.
The vulnerability could only be exploited by an attacker who persuaded a user to open a malicious document. There is no way for an attacker to force a malicious document to be opened.
