Vulnerability Name:

CCN-11536

Published:2003-03-13
Updated:2003-03-13
Summary:Microsoft Windows 2000 and Windows XP could allow a local attacker to obtain user passwords, caused by a vulnerability in the PostMessage() API function, which posts a message to the Windows API message queue. The PostMessage() API function fails to properly validate a message's handle and type before sending the message to any message queue. If the PostMessage() API function is invoked with the EM_SETPASSWORDCHAR message, a local attacker could obtain a victim's password from the Password dialog box.
