Name of the Vulnerable Software and Affected Versions Eclipse Jetty versions 9.4.37.v20210219 through 9.4.38.v20210224

Description The default compliance mode in Eclipse Jetty allows requests with URIs that contain %2e or %2e%2e segments to access protected resources within the WEB-INF directory. For example, a request to /context/%2e/WEB-INF/web.xml can retrieve the web.xml file, revealing sensitive information regarding the implementation of a web application.

Recommendations For Eclipse Jetty versions 9.4.37.v20210219 through 9.4.38.v20210224, update the start.d/http.ini file to include jetty.http.compliance=RFC7230 NO AMBIGUOUS URIS to enable the HttpCompliance mode RFC7230 NO AMBIGUOUS URIS as a workaround.
