K46901953:BIG-IP APM virtual server vulnerability CVE-2020-5874

Security Advisory

Original Publication Date: 30 Apr, 2020

Security Advisory Description

In certain circumstances, an attacker sending specifically crafted requests to
a BIG-IP APM virtual server may cause a disruption of service provided by the
Traffic Management Microkernel(TMM). (CVE-2020-5874)

Impact

An attacker may be able to perform a denial-of-service (DoS) attack on a BIG-IP
system by causing the TMM process to restart.

The data plane is only impacted and exposed when the virtual server is
configured to use OpenID connect. The control plane is not impacted by this
vulnerability.

Security Advisory Status

F5 Product Development has assigned ID 794561 (BIG-IP) to 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

To mitigate this vulnerability, you can remove the fallback host from the HTTP
profile on the client side. To do so, perform the following procedure:

Impact of action: The fallback host configuration option allows the BIG-IP
system to serve a 302 response to redirect clients to a specific website when
the pool associated with the virtual server is marked down. After you remove
the fallback host configuration option, the system does not serve any pages to
clients when the pool is unavailable.

 1. Log in to the Configuration utility.
 2. Go to Local Traffic > Profiles > Services > HTTP.
 3. Select the HTTP profile associated with the virtual server.
 4. In the Fallback Host box, delete all contents.
 5. Select Update.

    Note: Changes will take effect only for newly established connections.

K33572148:The BIG-IP ASM system may fail to mask a configured sensitive parameter in the Referer header value

Security Advisory

Original Publication Date: 30 Apr, 2020

Security Advisory Description

The BIG-IP ASM system may fail to mask a configured sensitive parameter in the
Referer header value.

This issue occurs when all of the following conditions are met:

  o You configured a sensitive parameter located in Security > Application
    Security > Parameters > Sensitive Parameters for a security policy.
  o The virtual server associated with the security policy receives a request
    containing the configured sensitive parameter in its query string.

Impact

The BIG-IP ASM system does not mask the configured sensitive parameter in a
redirected request, and the request exposes the value of the sensitive
parameter in the Referer HTTP header.

Symptoms

As a result of this issue, you may encounter the following symptom:

  o When a client request with a configured sensitive parameter, for example, 
    param, is received: 

    /users/testuser/crsf/1.phpparam=asd

    And the request is then redirected with the URI as part of the Referer
    header, the value of the sensitive parameter, param, is unmasked:

    GET /index.phpparam=123 HTTP/1.1
    Connection: keep-alive
    X-Forwarded-For: 192.168.5.1
    Referer: http://192.168.198.27/users/testuser/crsf/1.phpparam=asd
    Host: 192.168.198.27
    User-Agent: Apache-HttpClient/4.2.6 (java 1.5)

+------------------+-----------------+----------------------------------------+

Security Advisory Recommended Actions

Workaround

There is no workaround prior to BIG-IP 14.0.0. To work around this issue in
BIG-IP 14.0.0 and later, you can enable the Mask Value in Logs setting for the
Referer HTTP header in the affected security policy. To do so, perform the
following procedure:

Impact of workaround: Enabling this setting masks the value of the Referer
header in all requests, as well as all logs, regardless of whether there is
sensitive information in it or not. Depending on your application environment,
this may have an impact, especially when troubleshooting application issues.

 1. Log in to the Configuration utility.
 2. Go to Security > Application Security > Headers > HTTP Headers.
 3. For Currently edited policy, select the policy you want to modify.
 4. For HTTP Headers, select referer.
 5. For Mask Value in Logs, select the Enable check box.
 6. Select Update.
 7. Select Apply Policy.

K25165813:BIG-IP SSL connection Alert Timeout security exposure

Security Advisory

Original Publication Date: 30 Apr, 2020

Security Advisory Description

The mitigation for K41515225: BIG-IP SSL connection security exposure may not
work in all conditions.

If after applying the workaround in K41515225: BIG-IP SSL connection security
exposure, setting the Alert Timeout to its minimum value of 1 second, you
continue to experience the same issue (spike in network throughput and increase
resource usage), it may be due to the issue described in this article. This is
most commonly seen in extremely high bandwidth networks, as the remote host can
send a large amount of data to the BIG-IP system within the 1 second minimum
value of the Alert Timeout.

This issue occurs when all of the following conditions are met:

  o You configure a virtual server with Client SSL and Server SSL profiles.
  o The virtual server proxies an SSL connection.
  o One side of the SSL connection sends a FIN midstream to the BIG-IP system.
  o You performed the workaround described in K41515225: BIG-IP SSL connection
    security exposure and set the Alert Timeout value to its minimum value of 1
    second.

Impact

The BIG-IP system is capable of receiving, acknowledging, and dropping traffic
at extremely high bandwidths, and since the connection is no longer
bandwidth-limited by the original client, you may observe a spike in throughput
between the peer and the BIG-IP system. It is possible, depending on the
peer-side network, that this spike in throughput can exhaust available network
bandwidth between the BIG-IP system and the peer, even when the Alert Timeout
is set at the minimum value of 1 second.

Symptoms

As a result of this issue, you may encounter one or more of the following
symptoms:

  o You view increased network throughput between the peer and the BIG-IP
    system.
  o Connections on the peer system remain open indefinitely until the remote
    host completes transmitting data to the BIG-IP system.

Security Advisory Status

F5 Product Development has assigned ID 750278 to this issue. F5 has confirmed
that this issue exists in the products listed in the Applies to (see versions)
box, located in the upper-right corner of this article. For information about
releases, point releases, or hotfixes that resolve this issue, refer to the

+------------------+------------------+---------------------------------------+

^1In this fix, after you upgrade to a software version listed in the Fixes
Introduced In column, the SSL Alert Timeout option now supports the Immediate 
value, which makes the BIG-IP system reset both client and server side flows
after 1/1000 second. You need to configure your Server SSL profile and set the
SSL Alert Timeout to Immediate.

Security Advisory Recommended Actions

Workaround

There is no workaround for this issue. You need to upgrade your BIG-IP system
to a software version listed in the Fixes Introduced In column and configure
the SSL Alert Timeout setting to Immediate, which makes the BIG-IP system reset
both client and server side flows after 1/1000 second. Reducing the Alert
Timeout value will directly affect the amount of data transferred after the
original FIN is received. To do so, perform the following procedure:

Impact of workaround: Performing the following procedure should not have a
negative impact on your system.

 1. Log in to the Configuration utility.
 2. Go to Local Traffic > Profiles > SSL > Server SSL.
 3. Select the name of the profile associated with the virtual server.
 4. Next to Configuration, select Advanced.
 5. For Alert Timeout, select Immediate.
 6. Click Update.
    New SSL connections to the virtual server will use the new setting.

^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.

F5 will not develop a fix for vulnerable products that do not already have a
fixed version listed in this article, and will not update this table with
subsequent vulnerable releases in the associated branches. F5 recommends that
you update to more recent, non-vulnerable versions whenever feasible. For more
information, refer to K4602: Overview of the F5 security vulnerability response
policy.

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 enable the statemirror.secure database
variable protect the VLAN used for mirroring from untrusted entities. To do so,
perform one of the following procedures:

  o Enabling the statemirror.secure database variable
  o Protecting the VLAN used for mirroring from untrusted entities

Enabling the statemirror.secure database variable

To enable the statemirror.secure database variable, perform the following
procedure:

Impact of action: Performing the following procedure should not have a negative
impact on your system.

 1. Log in to the TMOS Shell (tmsh) by entering the following command:

    tmsh

 2. To enable the statemirror.secure database variable, enter the following
    command:

    modify /sys db statemirror.secure value enable

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 limit access to the local IPv6 F5
addresses using the following two methods:

  o Creating a packet filter rule to limit access to IPv6 address fc00:f5::1
  o Creating a BIG-IP AFM rule to limit access to IPv6 address fc00:f5::1

Creating a packet filter rule to limit access to IPv6 address fc00:f5::1

To create a packet filter rule, perform the following procedure:

 1. Log in to the BIG-IP Configuration utility.
 2. Navigate to Network > Packet Filters > Rules.
 3. Select the Create button.
 4. In the Name text box, enter the following content: 

    limit-access-to-fc00-f5-1-ipv6-rule

 5. For Order, select Last.
 6. For Action, select Discard.
 7. For Filter Expression Method, select Enter Expression Text.
 8. In the Filter Expression text box, enter the following content:

    ( ( ip6 )  ) and ( dst host fc00:f5::1 )

 9. Select the Finished button.

Creating a BIG-IP AFM rule to limit access to IPv6 address fc00:f5::1

Note: To mitigate this issue, BIG-IP AFM must be licensed and provisioned.

If no BIG-IP AFM policies exist, you must first create a policy using the name
of your choice and apply it to the global BIG-IP AFM context, detailed in steps
1 through 8. Otherwise, skip steps 1 through 8 and proceed with step 9 after
you log in to the BIG-IP Configuration utility:

 1. Log in to the BIG-IP Configuration utility.
 2. Navigate to Security > Network Firewall > Policies.
 3. Select the Create button and enter a policy name.
 4. Select Finished.
 5. Select the Active Rules tab.
 6. Select the Global link under Active Rules List.
 7. Under the Network Firewall section, change Enforcement to Enabled and
    select the policy name that you created.
 8. Click Update.
 9. Navigate to Security > Network Firewall > Policies.
10. Select your policy, and then select the Add Rule button.
11. In the Rule fields, add the following from defaults:

    Name: limit-access-to-fc00-f5-1-ipv6-afm-rule

    Protocol: Any

    Destination: fc00:f5::1 (Click the Add button after entering)

    Action: Drop

12. Select the Done Editing button.
13. To activate the new rule, select the Commit Changes to System button.

K65372933:BIG-IP HTTP/2 vulnerability CVE-2020-5875

Security Advisory

Original Publication Date: 30 Apr, 2020

Security Advisory Description

Under certain conditions, the Traffic Management Microkernel (TMM) may generate
a core file and restart while processing SSL traffic with an HTTP/2 full proxy.
(CVE-2020-5875)

request sequence can trigger a condition that may cause TMM to generate a core
file and restart. An attacker may be able to cause a BIG-IP system to produce a
core file, disrupting the flow of traffic and causing a failover to a standby
system.

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 issue, you can disable crypto hardware acceleration. To do so,
perform the following procedure:

Note: Disabling hardware-based crypto acceleration results in all crypto
actions processed in software, which may cause higher CPU and memory usage
based on traffic patterns.

Impact of workaround: The impact of the suggested workaround 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.

 1. Log in to the TMOS Shell (tmsh) by entering the following command:

    tmsh

 2. Disable crypto hardware acceleration by entering the following command:

    modify /sys db crypto.hwacceleration value disable
