Following my original post it has been brought to our attention that the highlighting exploit can be taken advantage of, and it a serious way. We are hastily preparing a new release. However that release contains a number of other fixes and additions and thus we carrying out some internal testing to limit the chances of other issues arising.

In the mean time we strongly, and I mean strongly! urge all our users to make the following change to viewtopic.php as a matter of urgency.

Open viewtopic.php in any text editor. Find the following section of code:

//
// Was a highlight request part of the URI?
//
$highlight_match = $highlight = ”;
if (isset($HTTP_GET_VARS[’highlight’]))
{
// Split words and phrases
$words = explode(’ ‘, trim(htmlspecialchars(urldecode($HTTP_GET_VARS[’highlight’]))));

for($i = 0; $i

If you are running ANY version of phpBB please make this simple fix.
