Security Advisory

Original Publication Date: 21 Dec, 2017

Latest   Publication Date: 04 Apr, 2018

Security Advisory Description

In some circumstances, the Traffic Management Microkernel (TMM) does not
properly handle certain malformed TLS1.2 records, which allows remote
attackers to cause a denial-of-service (DoS) or possible remote command
execution on the BIG-IP system. (CVE-2017-6164)

Impact

A remote attacker may be able cause a denial of service (DoS) or possibly run
a command remotely on the BIG-IP system.

^1The CVSSv3 score link takes you to a resource outside of AskF5, and it is
possible that the document may be removed without our knowledge.

^2 The specified products contain the affected code. However, F5 identifies
the vulnerability status as Not vulnerable because the attacker cannot exploit
the code in default, standard, or recommended configurations.


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.

Note: For details about how Security Advisory articles are versioned, and what
versions are listed in the table, refer to K51812227: Understanding Security
Advisory versioning.

K12044607:TMM vulnerability CVE-2017-6132

Security Advisory

Original Publication Date: 21 Dec, 2017

Latest   Publication Date: 03 Apr, 2018

Security Advisory Description

Undisclosed sequence of packets sent to BIG-IP High Availability state mirror
listeners (primary and/or secondary IP) may cause TMM to restart. (
CVE-2017-6132)

Impact

The BIG-IP system may temporarily fail to process traffic as it recovers from
a TMM restart, and devices configured as a high-availability (HA) pair may
fail over.


Security Advisory Status

F5 Product Development has assigned ID 653993 (BIG-IP) to this vulnerability.
Additionally, BIG-IP iHealth may list Heuristic H12044607 on the Diagnostics >
Identified > High page.

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.

K37404773:TMM vulnerability CVE-2017-6134

Security Advisory

Original Publication Date: 21 Dec, 2017

Latest   Publication Date: 03 Apr, 2018

Security Advisory Description

An undisclosed sequence of packets, sourced from an adjacent network may cause
TMM to crash. (CVE-2017-6134)

Impact

This issue is exposed in the default configuration. Traffic processing is
disrupted while the Traffic Management Microkernel (TMM) restarts. If the
affected F5 device is configured as part of a device group, the system will
trigger a failover to the peer device.


Security Advisory Status

F5 Product Development has assigned ID 655059 (BIG-IP), ID 658348 (BIG-IQ),
and ID 658341 (Enterprise Manager) to this vulnerability.

To determine if your product and version have been evaluated for this
vulnerability, refer to the Applies to (see versions) box. To determine if
your release is known to be vulnerable, the components or features that are
affected by the vulnerability, and for information about releases or hotfixes
that address the vulnerability, refer to the following table.

^1The CVSSv3 score link takes you to a resource outside of AskF5, and it is
possible that the document may be removed without our knowledge.

^2 The specified products contain the affected code. However, F5 identifies
the vulnerability status as Not vulnerable because the attacker cannot exploit
the code in default, standard, or recommended configurations.


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 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 K21232150: Considerations for upgrading BIG-IQ or F5 iWorkflow
systems.

K81137982: TMM vulnerability CVE-2017-6136

Security Advisory

Original Publication Date: Dec 21, 2017

Security Advisory Description

Undisclosed traffic patterns sent to BIG-IP virtual servers, with the TCP Fast
Open and Tail Loss Probe options enabled in the associated TCP profile, may
cause a disruption of service to the Traffic Management Microkernel (TMM). (
CVE-2017-6136)

Impact

An attacker may be able to disrupt traffic or cause the BIG-IP system to fail
over to another device in the device group.

Note: The Fast Open and the Tail Loss Probe TCP profile options are both
disabled in the default configuration, and both options must be enabled to
expose this vulnerability.

K34514540:TMM vulnerability CVE-2017-6138

Security Advisory

Original Publication Date: 21 Dec, 2017

Latest   Publication Date: 04 Apr, 2018

Security Advisory Description

Malicious requests made to virtual servers with an HTTP profile can cause the
TMM to restart. The issue is exposed with BIG-IP APM profiles, regardless of
settings. The issue is also exposed with the non-default "normalize URI"
configuration options used in iRules and/or BIG-IP LTM policies. (
CVE-2017-6138)

Impact

An attacker may be able to disrupt traffic or cause the BIG-IP system to fail
over to another device in the device group. This vulnerability affects systems
with any of the following configurations:

  o A virtual server associated with a BIG-IP APM profile.
  o A virtual server associated with an HTTP profile and a local traffic
    policy that has a rule condition with the HTTP URI and Use normalized URI 
    options enabled (the Use normalized URI option is disabled by default).

    For example, in the following configuration excerpt, the local traffic
    policy is vulnerable:

    ltm policy /Common/K34514540 {

        requires { http }
        rules {
            vulnerable {
                conditions {
                    0 {
                        http-uri
                        path
                        normalized
                        values { /exploitable }
                    }
                }

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.

Note: For details about how Security Advisory articles are versioned, and what
versions are listed in the table, refer to K51812227: Understanding Security
Advisory versioning.

Mitigation

To mitigate this vulnerability, you should avoid using:

  o the normalize option with L7 policies.
  o the -normalize option with HTTP::uri, HTTP::query, or HTTP::path iRules
    commands.

Impact of action: The impact of the suggested mitigation depends on the
specific environment. F5 recommends testing any such changes during a
maintenance window with consideration to the possible impact on your specific
environment.

K07369970:TMM vulnerability CVE-2017-6151

Security Advisory

Original Publication Date: 21 Dec, 2017

Latest   Publication Date: 03 Apr, 2018

Security Advisory Description

Undisclosed requests made to BIG-IP virtual servers that use the "HTTP/2
profile" may result in a disruption of service to TMM. (CVE-2017-6151)

Impact

An attacker may be able to disrupt traffic or cause the BIG-IP system to fail
over to another device in the device group. This vulnerability affects the
BIG-IP system when virtual servers are configured with an HTTP/2 profile.


Security Advisory Status

F5 Product Development has assigned ID 668501 (BIG-IP) to this vulnerability.
