Overview

org.eclipse.jetty:jetty-webapp is a maven plugin for Jetty web application support.

Affected versions of this package are vulnerable to Information Exposure. The default compliance mode 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. This can reveal sensitive information regarding the implementation of a web application.
