CVE-2019-10247 is an information-disclosure vulnerability in Eclipse Jetty's DefaultHandler. When a request does not match a configured context, the default 404 response can render configured contexts as HTML links and disclose the fully qualified base-resource filesystem location associated with each context. It affects Jetty 7.x, 8.x, 9.2.27 and earlier, 9.3.26 and earlier, and 9.4.16 and earlier.
