| Business Impact: |
Compromise of networks and machines using affected versions of Microsoft Office may lead to exposure of confidential information, loss of productivity, and further network compromise. Attacks of this sort are usually launched by sending the victim and email with an attachment or by redirecting the user to a malicious web page. Successful exploitation would grant an attacker the privileges of the currently logged on user. |

| Technical Description: |
Microsoft Office will, by default, prompt the user with a warning if they attempt to open a document with a known flawed COM object embedded in the file. By leveraging a transitive trust issue in the way Office handles the instantiation of objects, the security settings can be bypassed allowing an attacker to circumvent the normal warning. With this bypass, an attacker can embed and exploit a known flawed control in a document resulting in remote code execution. |
