* BIG-IP versions 11.5.4 through 11.6.1 contain the vulnerable code; however,
BIG-IP systems using these versions do not use the vulnerable code in a way
that exposes the vulnerability in the default, standard configuration or
recommended use case. The issue may be exposed through advanced, unsupported
customization.
# The f5-rest-node package on the BIG-IP system may be updated when the BIG-IP
system is managed by a BIG-IQ Cloud and Orchestration system or an iWorkflow
system. To verify if your BIG-IP system is running a vulnerable version of the
f5-rest-node package, you can run the f5-rest-node -v command from the command
line. At the time that this article is published, the latest vulnerable
version of the f5-rest-node package is 4.2.3 in BIG-IP 12.1.1 HF1. This
article will be updated with the fixed version of the f5-rest-node package
when the version is released with a fixed BIG-IP software version.
Vulnerability 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 Versions known to be not vulnerable 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.
To determine the necessary upgrade path for your BIG-IQ system, you should
understand the BIG-IQ product offering name changes. For more information,
refer to SOL21232150: Considerations for upgrading BIG-IQ or F5 iWorkflow
systems.
Mitigation
To mitigate this vulnerability for affected F5 products with the f5-rest-node
package, you should only permit management access to the system over a secure
network and limit access to trusted users. For more information, refer to
SOL13309: Restricting access to the Configuration utility by source IP address
(11.x - 12.x) and SOL13092: Overview of securing access to the BIG-IP system.
