1.Cross-site request forgery (getshell)
 
vulnerable file: /admin/user_ajax.php
 
detail:
case "savegroups2":
try
{
    $groups = $_POST['groups'];
    if(is_array($groups))
    {
        foreach($groups as $group)
        {
            $db->row_update("groups", $group, "id={$group['id']}");
        }
    }
    $rows = $db->row_select("groups", "", 0,
"groupid,groupname,popedom,starnum", "groupid");
    $groups = array();
    foreach($rows as $row)
    {
        $groups["{$row['groupid']}"] = $row;
    }
    writeGroupsCache();
    succeedFlag();
}
catch(Exception $e)
{
    echo($e);
}
break;
 
Update the information, by writeGroupCache () function to update the
information written to \cache\groups.php them, direct access to the
\cache\groups.php you can get shell.

    $code = stripslashes($_POST['code']);
    writeFile("collectrules/{$id}.php", $code);
    succeedRes();
}
catch(Exception $e)
{
    echo($e);
}
break;
