CloudLink: Il server HTTPS remoto non applica HTTP Strict Transport Security (HSTS)

CloudLink: Report di scansione della sicurezza:

The remote HTTPS server is not enforcing HTTP Strict Transport Security (HSTS)
The remote HTTPS server does not send the HTTP "Strict-Transport-Security" header

HSTS è un'intestazione di risposta opzionale che può essere configurata sul server per indicare al browser di comunicare solo tramite HTTPS. La mancanza di HSTS consente attacchi di downgrade, attacchi man-in-the-middle di stripping SSL e indebolisce le protezioni contro il dirottamento dei cookie.

- Navigate to the Cloudlink UI login page.
- Right click on white empty space and select 'Inspect'.
- Select the 'Network' tab.
- Select one of the Cloudlink HTTP requests on the left panel.
- Match the response headers you're seeing to what we expect to see from the KB article

La risposta HTTP ha tutte le intestazioni ed è impostata per impostazione predefinita da https://docs.spring.io/autorepo/docs/spring-security/4.2.3.RELEASE/reference/html/headers.html
