Igor Guzenko created DRILL-7642: ----------------------------------- 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. -- This message was sent by Atlassian Jira (v8.3.4#803005)
