I made some tests and seems to me that just environments where magic_quotes_gpc = 'Off' are affected (which is not default on php). When magic_quotes_gpc = On, the query that is sent to database is interpreted as: SELECT active, view FROM nuke_modules WHERE title='\' OR 1=2 /*' Which is properly slashed. But, if we do have magic_quotes_gpc = Off, it's interpreted as: SELECT active, view FROM nuke_modules WHERE title='' OR 1=2 /*' Which is exploitable.

You did neither issue a "addslashes()" as appropriate for SQL-commands, nor did you explain, why a variable set by a POST or a COOKIE could be worse than anything you could give any URL by appending '?name=...' or '&name=...' (->GET vars)If you read the code and original advisory, there is filtering already in place within the PHP-Nuke framework that monitors HTTP GETs. As such, this 'exploit' makes of variables which should only be passed via HTTP GETs and not POSTs nor cookies. Proper data sanitization for this is simply to retrieve what is expected: $name = $_GET['name']; The function you specify like http://php.net/addslashes is neither here nor there. Why use that function for a variable in POST or cookies when it is clearly expected to be returned via GET alone?
