amigos tenham cuidado com a versão final do SMF, como tudo o que é novo, pode trazer sempre os seus errozitos, pelos vistos a nova versão não é excepção à regra.
QuoteSoftware: Simple Machines Forum 1.x
Description:
Jessica Hope has discovered a vulnerability in Simple Machines Forum, which can be exploited by malicious people to conduct cross-site scripting attacks.
If the "image" parameter is passed when accessing attachments, Simple Machines Forum automatically sets the "image/gif" MIME type. Since the Microsoft Internet Explorer browser overrides HTTP headers and tries to guess MIME types via the content instead, this can be exploited to execute arbitrary HTML and JavaScript code in a user's Internet Explorer session in context of an affected site.
The vulnerability is confirmed in version 1.1. Other versions may also be affected.
Solution:
Edit the source code to ensure that the attachment is an image file.
