Debian DLA-2688-1 : jetty9 security update

medium Nessus Plugin ID 150904

Language:

Synopsis

The remote Debian host is missing a security update.

Description

Steven Seeley discovered that in jetty, a Java servlet engine and webserver, requests to the ConcatServlet and WelcomeFilter are able to access protected resources within the WEB-INF directory. An attacker may access sensitive information regarding the implementation of a web application.

For Debian 9 stretch, this problem has been fixed in version 9.2.30-0+deb9u2.

We recommend that you upgrade your jetty9 packages.

For the detailed security status of jetty9 please refer to its security tracker page at:
https://security-tracker.debian.org/tracker/jetty9

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
