Filters check

If you change the value of the filter ( inspect element chrome, and than change the value of the select box ) to "-1", you will get the mysql error what meanse bad validation of the incoming data...

Solution:

file: /usr/local/ispconfig/interface/lib/classes/listform.inc.php

Function: getPagingSQL

After code ( line ~197 ): if(!empty($_POST['search_limit']) AND $app->functions->intval($_POST['search_limit'])){ $_SESSION['search']['limit'] = $app->functions->intval($_POST['search_limit']); }

Add: if(preg_match('{^[0-9]$}',$_SESSION['search']['limit'])){ $_SESSION['search']['limit'] = 15; }
