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.

The BIG-IP system is also not vulnerable if it meets the following criteria: o The BIG-IP system is running any of the following versions: - 11.6.0 - 11.6.0 HF4 - 11.5.0 - 11.5.2 HF1 - 11.4.0 - 11.4.1 HF3 - 11.2.1 - 11.2.1 HF10 o The BIG-IP system has virtual servers that are not associated with TCP Analytics profile but associated with TCP profile configured with the following settings: - Multipath TCP (mptcp) setting is disabled (default) - Rate Pace (rate-pace) setting of the Congestion Control section is disabled (default) - Tail Loss Probe (tail-loss-probe) setting of the Loss Detection and Recovery section is disabled (default) - Fast Open (fast-open) setting of the Connection Setup section is disabled (default) - Congestion Metrics Cache Timeout (cmetrics-cache-timeout) setting of the Congestion Control section is set to zero (default) - Congestion Control (congestion-control) setting of the Congestion Control section is set to one of the following: - Reno - New Reno - High Speed (default) - Scalable - Nagle's Algorithm setting of the Data Transfer section is set to either Enabled or Disabled (default) 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 . Mitigation To mitigate this vulnerability, you can enable the Verified Accept setting of the TCP profile associated with the affected virtual server. To do so, 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 Configuration utility. 2. Navigate to Local Traffic > Profiles > Protocol > TCP. 3. Click on the name of the desired TCP profile. 4. To enable the setting, select Verified Accept; this setting is disabled by default. 5. To save the change, click Update.
