K31152411: BIG-IP Analytics vulnerability CVE-2019-6655
Security Advisory
Original Publication Date: 25 Sep, 2019
Security Advisory Description
BIG-IP platforms provisioned with AAM, AFM, Application Visibility and
Reporting (AVR), APM, ASM, and/or PEM may leak sensitive data. (CVE-2019-6655)
Impact
BIG-IP (AAM, AFM, AVR, APM, ASM, PEM)
The vulnerability is only present on BIG-IP systems provisioned with AAM, AFM,
AVR, APM, ASM, and/or PEM on the following interfaces:
o Management Interface in versions prior to 14.0.0.
o Self IP addresses with Port Lockdown configured as Allow All.
Note: The default setting for Port Lockdown is Allow None.
In both of these configurations, a malicious actor may be able to connect to
the affected interface to extract sensitive information on the system,
including but not limited to, client and server IP addresses, client request
URIs, and metadata for attacks detected by the system.
BIG-IP (LTM, DNS, Edge Gateway, FPS, GTM, Link Controller, WebAccelerator),
BIG-IQ, Enterprise Manager, and F5 iWorkflow / Traffix SDC
There is no impact; these F5 products are not affected by this vulnerability.

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
F5 recommends upgrading to a fixed software version to fully mitigate this
vulnerability.
Note: It is not possible to provide these fixes in an engineering hotfix for
prior versions of software. A full upgrade to a fixed release version is
required.
If you are unable to upgrade the affected systems at this time, you may
consider using the following as an interim fix:
Self IP
Change the self IP port lockdown settings from Allow All to Allow None or Allow
Default. If you require additional ports to open, you should use Allow Custom.
F5 recommends avoiding Allow All entirely. For more information about
configuring the port lockdown settings, refer to K17333: Overview of port
lockdown behavior (12.x - 15.x).
Management interface
There is no full mitigation available other than upgrading to a fixed software
version. A partial mitigation is available from F5 Support.
