Elastix 2.4 ARI vulnerability Patch

The recent vulnerability in the Asterisk and Freepbx ARI login.php file is not addressed in an update to ARI in the unembedded freepbx on Elastix 2.4.

This will mean that your systems will still be vulnerable.

We have produced a patch that you can apply to address this. The patch can be downloaded  from and applied as detailed below.

logon to the server console

cd /var/www/html/recordings/includes
cp login.php /root/login.php.ari
patch < ari.patch 

Then to check either login to server ARI interface or 

cat login.php |grep json

and you should get the following output

$buf = json_decode($_COOKIE['ari_auth'],true);
$data = json_decode($crypt->decrypt($data,$ARI_CRYPT_PASSWORD),true);
$data = $crypt->encrypt(json_encode($data),$ARI_CRYPT_PASSWORD);
$buf = json_encode(array($data,$chksum));

also check to see if you have the file in the fw_ari directory.

ls -l /var/www/html/admin/modules/fw_ari/htdocs_ari/includes

if there is a login.php there then copy over the patched version.

cp /var/www/html/recordings/includes/login.php  /var/www/html/admin/modules/fw_ari/htdocs_ari/includes/login.php

After these actions check that the file ownership is still correct

if not 

chown asterisk:asterisk /var/www/html/recordings/includes/login.php 

This patch also applies to any older version of ARI out there.

also to be on the lookout for two suspicious files, named “” or “” respectively. If you see these two files remove them immediately!
