sol06045217: TMM vulnerability CVE-2016-5022
Security Advisory
Original Publication Date: 29/08/2016
Vulnerability Description
An unauthenticated remote attacker maybe be able to disrupt services on the
BIG-IP system with maliciously crafted network traffic. This vulnerability
affects virtual servers of all types and for all protocols. Self IP addresses
may also be exposed to this vulnerability. The management interface is not
affected. (CVE-2016-5022)
Impact
Traffic Management Microkernel (TMM) may restart and temporarily fail to
process traffic. This issue is related to Packet Filtering, which is enabled by
default on the BIG-IP system. There is additional risk if the database variable
tm.acceptipoptions is enabled.
Security Issue Status
F5 Product Development has assigned ID 573124 and ID 472178 (BIG-IP), ID 598543
(BIG-IQ/iWorkflow) and ID 598546 (Enterprise Manager) to this vulnerability.

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 reduce your risk of exposure to this vulnerability, ensure that the database
variable tm.acceptipoptions is disabled. While this issue may be mitigated by
disabling packet filters, F5 does not recommend this action. There is no other
mitigation at this time. To disable the database variable tm.acceptipoptions,
perform the following procedure:
Impact of procedure: Disabling this database variable will prevent the system
from processing IPv4 packets with IP options; this may affect VXLAN if
configured.
Log in to the Traffic Management Shell (tmsh) by typing the following
command:
tmsh
Disable the database variable tm.acceptipoptions by typing the following
command:
modify sys db tm.acceptipoptions value disable
