Security Advisory Recommended Actions

If you are running a version listed in the Versions known to be vulnerable
column, you can eliminate this vulnerability by upgrading to a version listed
in the Fixes introduced in column. If the table lists only an older version
than what you are currently running, or does not list a non-vulnerable version,
then no upgrade candidate currently exists.

Mitigation

To mitigate this vulnerability, you can implement firewall rules to limit
access to ports 28015 and 29015 only from devices that are in the BIG-IQ
cluster (for example, an HA pair or Data Collection Device systems). To do so,
you can use the iptables utility on the BIG-IQ system or an external firewall.

Using the iptables utility on the BIG-IQ system to limit access to ports 28015
and 29015

Impact of action: Incorrect use of the iptables utility can result in service
interruption on the BIG-IQ system.

 1. Log in to the command line of the affected BIG-IQ system.
 2. Add the list of BIG-IQ cluster devices (HA pair or Data Collection Device
    systems) for access to ports 28015 and 29015 by entering the following
    command syntaxes:

    iptables -A INPUT -p tcp -s <IP addresses of BIG-IQ cluster devices
    separated by commas> --dport 28015 -j ACCEPT
    iptables -A INPUT -p tcp -s <IP addresses of BIG-IQ cluster devices
    separated by commas> --dport 29015 -j ACCEPT

    For example, you would enter the following commands to allow BIGIQDCD1 (
    192.168.137.192) and BIGIQDCD2 (192.168.137.201) access to ports 28015 and
    29015:

    iptables -A INPUT -p tcp -s 192.168.137.192,192.168.137.201 --dport 28015
    -j ACCEPT
    iptables -A INPUT -p tcp -s 192.168.137.192,192.168.137.201 --dport 29015
    -j ACCEPT

 3. Deny access for all other IP addresses to ports 28015 and 29015 by entering
    the following commands:

    iptables -A INPUT -p tcp --dport 28015 -j DROP
    iptables -A INPUT -p tcp --dport 29015 -j DROP

 4. Save the changes by entering the following command: 

    /sbin/service iptables save
