Description:
A weakness has been discovered in phpBB, which can be exploited by malicious people to disclose certain system information.
The weakness is caused due 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 support for remote avatars is enabled (not default setting).
The weakness has been confirmed in version 2.0.17. Other versions may also be affected.
Solution:
Disable remote avatars in the "Avatar Settings" (default setting).
