For Eclipse Jetty versions <= 9.4.40, <= 10.0.2, <= 11.0.2, it is possible for requests to the ConcatServlet with a doubly encoded path to access protected resources within the WEB-INF directory. For example a request to /concat?/%2557EB-INF/web.xml can retrieve the web.xml file. This can reveal sensitive information regarding the implementation of a web application.

More info on this vulnerability can be found at <https://srcincite.io/blog/2021/07/13/fswa-2021-zero-day-give-away.html&gt; where the original author, Steven Steely of Source Insight, shows an example of how this vulnerability could be exploited to leak sensitive credentials from configuration files and combined this with a 0day deserialization vulnerability in Apache Shiro in the rememberMe cookie to gain RCE. For this reason, given a real world example of how this could be used to gain RCE on a typical deployment, I have elevated the Attacker Value.

Overall this vulnerability in a nutshell allows unauthenticated users to leak the content of files on the target system provided the target file is within the web root (aka the attacker can’t leak the content of files outside of the web root). Provided a user can leak sensitive info (which is not that uncommon), they can utilize this information to then conduct privilege elevation attacks and bypass authentication.
