Microsoft IE userData storeuserData Cookie Privacy Setting Bypass
Local Access Required
Loss of Integrity
Microsoft IE userData storeuserData function contains a flaw that may allow a malicious user to store persistent data (much like a cookie) on a victim's computer regardless of privacy settings. Therefore, the privacy setting gives the user a false sense of privacy protection against tracking cookie and other such privacy attacks.
Currently, there are no known upgrades or patches to correct this issue. It is possible to correct the flaw by implementing the following workaround(s): In the "Security" tab in "Internet Options" open "Custom Level". In the new window disable "UserData Persistance".
