Background
Eclipse Jetty is a Java-based web server and servlet container. It is widely used for hosting web applications and provides a lightweight and scalable solution. The vulnerability identified as CVE-2019-10247 affects versions 7.x, 8.x, 9.2.27 and older, 9.3.26 and older, and 9.4.16 and older of the Jetty server. This vulnerability exposes the configured fully qualified directory base resource location when a 404 error occurs due to a missing Context that matches the requested path.
Vulnerability Detail
The default behavior of Jetty includes a DefaultHandler, responsible for reporting 404 errors. This handler presents the various configured contexts as HTML for users to click through. However, this HTML output contains the fully qualified directory base resource location for each context, which can be exploited by attackers to gain sensitive information about the server's file system structure. This vulnerability has a CVSS score of 5.3, indicating a moderate severity level.

Workaround
As a temporary workaround, users can remove the DefaultHandler from the Jetty server configuration. This can be achieved by modifying the server's configuration file and removing the DefaultHandler from the Handler tree. However, this workaround may impact the server's error handling and reporting capabilities, so upgrading to the fixed versions is strongly recommended.
Conclusion
The installation information leak vulnerability in Eclipse Jetty exposes the fully qualified directory base resource location, potentially compromising the server's file system structure. It is crucial to upgrade to the fixed versions of Jetty to mitigate this vulnerability. For further assistance and support in vulnerability remediation, please contact DevNack.com.
