Opened: Jun 13, 2019

Severity: 3-Major

Symptoms

Some applications requires the Strict-transport-Policy header to appear in all responses. BIG-IP internal responses do not add this header.

Impact

Responses arrives to the browser without the Strict-transport-Policy header.

Conditions

- ASM is provisioned with CAPTCHA/CSI challenge enabled or - DoS is provisioned with CAPTCHA/CSI enabled or - Bot Defense is provisioned with CAPTCHA mitigation/Browser JS verification/Device ID collection is enabled.

Workaround

Create an iRule to add the header to the response.

Fix Information

Adding a BigDB parameter (asm.strict_transport_policy) which allows to add the header to all internal responses. Default is disabled.
