-----------------------------------
Summary: Get rid of Web UI inline code to improve security
Key: DRILL-7642
URL: https://issues.apache.org/jira/browse/DRILL-7642
Project: Apache Drill
Issue Type: Improvement
Components: Security, Web Server
Reporter: Igor Guzenko
Application of *Content-Security-Policy * response header with value
*default-src https:* breaks down numerous components in Drill Web UI. The main
reason for the failures is the inline code used widely in Web UI. According to
web security best practices, such code is [considered
harmful|https://developers.google.com/web/fundamentals/security/csp#inline_code_is_considered_harmful]
and should be avoided. In order to make UI work, we can apply the only header:
{code}
"Content-Security-Policy": "default-src https:; script-src
'unsafe-inline' https:; style-src 'unsafe-inline' https:; font-src data:
https:; img-src data: https:"
{code}
Which isn't as strict as necessary. Therefore it is necessary to rewrite all
places where inline code is used and ensure that CSP header can provide really
strict rules for securing web pages.
