Jeff Young created SLING-2572: --------------------------------- Summary: Redirect validating service Key: SLING-2572 URL: https://issues.apache.org/jira/browse/SLING-2572 Project: Sling Issue Type: Improvement Components: General Reporter: Jeff Young
Clients need to validate redirects to esure that they point on-site (or perhaps to an authority on a white-list) to prevent phishing attacks. A Sling service which performed this would allow consistency (and a single point of extension). There already exists AuthUtil.isRedirectValid() [0], but it doesn't handle URLs (only paths), and disallows relative paths (the second of which, at least, is widely used). There is also a referrer validating service [1] which might provide a better starting point. Lastly, if we had backward-compatibility concerns with some of the algorithms encoded in those methods/services, we might choose to provide a very basic default implementation which simply drops any scheme and/or authority from the URL, and let customers do white-lists and/or other more sophisticated checks as customizations.
