HTTP Strict Transport Security (HSTS) via HTTP

Severity: Information
Summary#

HTTP Strict Transport Security header is sent via an HTTP response which must be sent in HTTPS responses instead.

Impact#
Web browsers will ignore the HSTS implementation and the users will not be able to take advantage of HSTS. This renders the HSTS implementation useless. Not having HSTS will make MITM attacks easier for attackers.
