*Summary:*
--------------
A security flaw allows an attacker to know the full path of the web system.

*Details:
-----------
*SSI.php Line 294:
// Fetch a post with a particular ID. By default will only show if you have
permission to the see the board in question - this can be overriden.
function ssi_fetchPosts($post_ids, $override_permissions = false,
$output_method = 'echo')
{

$post_id is not defined. Possible fix: ($post_id = false)
