CVE-2004-0121 is an argument injection vulnerability in Microsoft Outlook 2002 caused by insufficient filtering of parameters supplied through specially crafted mailto: URLs before those parameters are passed as arguments to OUTLOOK.EXE. By manipulating how the mailto: URL is interpreted, an attacker can alter the way Outlook is invoked and inject unintended arguments. Successful exploitation can cause script code to run in the Local Machine zone and can lead to arbitrary program execution.
