Launchpad HTTP headers security improvement #432

Open Aldekein opened 3 years ago

Aldekein commented 3 years ago

Some HTTP headers required for security are not set on https://launchpad.ethereum.org/ With a carefully crafted combination of stylesheets, iframes, and text boxes on a phishing webpage, a user can be led to believe they are interacting with a real launchpad website, but are instead typing into an invisible frame controlled by the attacker.

Proposed fix

As described in greater detail in OWASP project (https://owasp.org/www-project-secure-headers/) the website security will benefit from instructing browser by adding following headers to responses at https://launchpad.ethereum.org/:

X-Frame-Options:  SAMEORIGIN
Content-Security-Policy: frame-ancestors 'none'
X-Content-Type-Options: nosniff
X-Permitted-Cross-Domain-Policies: none
Referrer-Policy: origin-when-cross-origin
X-XSS-Protection: 0
Strict-Transport-Security: max-age=15768000;includeSubdomains

Additional notes:

  1. The proposed Content-Security-Policy header is a minimal required version, it may benefit from more precise tuning based on specifics of Launchpad.
  2. Strict-Transport-Security header is already present, but it does not include includeSubdomains flag.

@hwwhww @CarlBeek could you help with this or point me to a person who can?

Thanks for bringing this to my attention and I apologies for the delayed response. I have raised this issue with devops internally so we should get this sorted ASAP.

Not sure if this would fix all issues but here's the Netlify configuration we did for HTTP response headers on ethereum.org: https://github.com/ethereum/ethereum-org-website/pull/744
