Another SQL injection vulnerability in the upload feature:

If you upload a file as an attachment, save the page, and manipulate the value of the "file_array" element(make a new array, serialize, base 64 encode), you can insert an unescaped statement at the end of another SQL statement.

Example file_array element setting:

YToxOntpOjI1O3M6MTI6IjE7KTAwJ2wnbCcoIiI7fQ==

Will should cause an error to be entered in the fudforum error log, which you can see to verify the problem exists.

I've added additional checks, but the problem is actually less serious, only the key value is used, the value is not used in SQL.
