Vulnerability Note VU#305206
Microsoft Outlook fails to properly filter parameters passed via "mailto:" URL
A vulnerability in the way that Microsoft Outlook 2002 handles a certain type of hyperlink could allow a remote attacker to execute arbitrary code on the vulnerable system.
Microsoft Outlook provides a centralized application for managing and organizing e-mail messages, schedules, tasks, notes, contacts, and other information. Outlook is included as a component of newer versions of Microsoft Office and available as a stand-alone product.
Outlook 2002 exposes a vulnerability due to inadequate checking of parameters passed to the Outlook email client. The vulnerability is caused by the way a mailto: URL is interpreted. By creating a specially formatted mailto: URL an attacker may be able to alter the way that Outlook is invoked in a manner that allows code execution. The malicious code could be delivered to the victim via a specially-crafted HTML email message or from an intruder-controlled webpage.
An attacker could execute arbitrary code of their choosing on the system running the vulnerable version of Outlook. Upon successful exploitation, the malicious code would be executed in the context of the "Local Machine" Internet Explorer zone under the user running Outlook.
