[1.7 - 1.7.6] Security fix in global.php
« on: April 02, 2009, 03:27:36 PM »
In global.php find:

4images version 1.7

if (isset($HTTP_GET_VARS['l']) || isset($HTTP_POST_VARS['l'])) {
  
$l = (isset($HTTP_GET_VARS['l'])) ? trim($HTTP_GET_VARS['l']) : trim($HTTP_POST_VARS['l']);
  if (
file_exists(ROOT_PATH.'lang/'.$l.'/main.php')) {
    
$config['language_dir'] = $l;
  }
}


Replace it with:

$l null;
if (isset(
$HTTP_GET_VARS['l']) || isset($HTTP_POST_VARS['l'])) {
  
$requested_l = (isset($HTTP_GET_VARS['l'])) ? trim($HTTP_GET_VARS['l']) : trim($HTTP_POST_VARS['l']);
  if (!
preg_match('#\.\.[\\\/]#'$requested_l) && $requested_l != $config['language_dir'] && file_exists(ROOT_PATH.'lang/'.$requested_l.'/main.php')) {
    
$l $requested_l;
    
$config['language_dir'] = $l;
  }
}





4images version 1.7.1 - 1.7.6

  if ($requested_l != $config['language_dir'] && file_exists(ROOT_PATH.'lang/'.$requested_l.'/main.php')) {

Replace it with:

  if (!preg_match('#\.\.[\\\/]#'$requested_l) && $requested_l != $config['language_dir'] && file_exists(ROOT_PATH.'lang/'.$requested_l.'/main.php')) {





For these who installed [MOD] Language select with cookies support and can't find anything mentioned above, then you'll need find in global.php:

if (isset($HTTP_GET_VARS['l']) || isset($HTTP_POST_VARS['l'])) {
  
$l = (isset($HTTP_GET_VARS['l'])) ? trim($HTTP_GET_VARS['l']) : trim($HTTP_POST_VARS['l']);
  if (
file_exists(ROOT_PATH.'lang/'.$l.'/main.php')) {
    
$config['language_dir'] = $l;
    
setcookie('4images_lang'$l, (time()+ 60 60 24 365), "/"""0);
  }
}
else
{
  if (isset(
$HTTP_COOKIE_VARS['4images_lang']) && file_exists(ROOT_PATH.'lang/'.$HTTP_COOKIE_VARS['4images_lang'].'/main.php'))
  {
    
$l $config['language_dir'] = $HTTP_COOKIE_VARS['4images_lang'];
  }
}


And replace it with:

if (isset($HTTP_GET_VARS['l']) || isset($HTTP_POST_VARS['l'])) {
  
$requested_l = (isset($HTTP_GET_VARS['l'])) ? trim($HTTP_GET_VARS['l']) : trim($HTTP_POST_VARS['l']);
  if (!
preg_match('#\.\.[\\\/]#'$requested_l) && file_exists(ROOT_PATH.'lang/'.$requested_l.'/main.php')) {
    
$l $requested_l;
    
$config['language_dir'] = $l;
    
setcookie('4images_lang'$l, (time()+ 60 60 24 365), "/"""0);
  }
}
else
{
  if (isset(
$HTTP_COOKIE_VARS['4images_lang']) && !preg_match('#\.\.[\\\/]#'$HTTP_COOKIE_VARS['4images_lang']) && file_exists(ROOT_PATH.'lang/'.$HTTP_COOKIE_VARS['4images_lang'].'/main.php'))
  {
    
$l $config['language_dir'] = $HTTP_COOKIE_VARS['4images_lang'];
  }
}

(I've already updated the code in the mentioned mod with this fix)




P.S.
thanks to 4dabdura for reporting this bug and Jan for providing us with the fix.

Habt ihr das im "Downloadpaket" schon beigefügt? Damit andere, die 4images z.B heute einsetzen wollen bzw. downloaden wollen das nicht hier extra suchen müssen!
Beste Grüße

scheinbar soll bald die 1.7.7 kommen.
ich würde es begrüssen, dass die Version so schnell wie möglich ausgelöst wird.

Denn wir reden hier von Sicherheit, die der User/Kunde so nicht hat!

Thank you for the follow-up

One more stupid post and I'm gone. Ops, I did it again..."thank you for the subject" - what kind of reply is this? now I'm banned for sure.
