Description:
rgod has discovered a weakness in Simple Machine Forum, which can be exploited by malicious people to disclose certain system information.
The weakness is caused to the application allowing users to use external files as avatars. This can be exploited to gather information (e.g. IP addresses, browser types) of other users, who view a forum post containing an external avatar image.
Successful exploitation requires that the user is allowed to specify external files as avatar.
The weakness has been confirmed in version 1.0.5. Other versions may also be affected.
Solution:
Configure the user group permissions to disallow the use of external avatars.
