The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - jetty: Timing channel attack in util/security/Password.java (CVE-2017-9735)

  - jetty: full server path revealed when using the default Error Handling (CVE-2018-12536)

  - In Eclipse Jetty versions 1.0 thru 9.4.32.v20200930, 10.0.0.alpha1 thru 10.0.0.beta2, and 11.0.0.alpha1     thru 11.0.0.beta2O, on Unix like systems, the system's temporary directory is shared between all users on     that system. A collocated user can observe the process of creating a temporary sub directory in the shared     temporary directory and race to complete the creation of the temporary subdirectory. If the attacker wins     the race then they will have read and write permission to the subdirectory used to unpack web     applications, including their WEB-INF/lib jar files and JSP files. If any code is ever executed out of     this temporary directory, this can lead to a local privilege escalation vulnerability. (CVE-2020-27216)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

This plugin has been deprecated as it does not adhere to established standards for this style of check.

Update to latest upstream release in order to fix CVE-2017-9735

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

It was discovered that Jetty, a Java servlet engine and webserver, was vulnerable to a timing attack which might reveal cryptographic credentials such as passwords to a local user.

For Debian 7 'Wheezy', these problems have been fixed in version 6.1.26-1+deb7u1.

We recommend that you upgrade your jetty packages.

Backport fix for CVE-2017-9735

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Several vulnerabilities were discovered in jetty, a Java servlet engine and webserver. An attacker may reveal cryptographic credentials such as passwords to a local user, disclose installation paths, hijack user sessions or tamper with collocated webapps.

CVE-2017-9735

Jetty is prone to a timing channel in util/security/Password.java, which makes it easier for remote attackers to obtain access by observing elapsed times before rejection of incorrect passwords.

CVE-2018-12536

On webapps deployed using default Error Handling, when an intentionally bad query arrives that doesn't match a dynamic url-pattern, and is eventually handled by the DefaultServlet's static file serving, the bad characters can trigger a java.nio.file.InvalidPathException which includes the full path to the base resource directory that the DefaultServlet and/or webapp is using. If this InvalidPathException is then handled by the default Error Handler, the InvalidPathException message is included in the error response, revealing the full server path to the requesting system.

CVE-2019-10241

The server is vulnerable to XSS conditions if a remote client USES a specially formatted URL against the DefaultServlet or ResourceHandler that is configured for showing a Listing of directory contents.

CVE-2019-10247

The server running on any OS and Jetty version combination will reveal the configured fully qualified directory base resource location on the output of the 404 error for not finding a Context that matches the requested path. The default server behavior on jetty-distribution and jetty-home will include at the end of the Handler tree a DefaultHandler, which is responsible for reporting this 404 error, it presents the various configured contexts as HTML for users to click through to. This produced HTML includes output that contains the configured fully qualified directory base resource location for each context.

CVE-2020-27216

On Unix like systems, the system's temporary directory is shared between all users on that system. A collocated user can observe the process of creating a temporary sub directory in the shared temporary directory and race to complete the creation of the temporary subdirectory. If the attacker wins the race then they will have read and write permission to the subdirectory used to unpack web applications, including their WEB-INF/lib jar files and JSP files. If any code is ever executed out of this temporary directory, this can lead to a local privilege escalation vulnerability.

This update also includes several other bug fixes and improvements.
For more information please refer to the upstream changelog file.

For Debian 9 stretch, these problems have been fixed in version 9.2.30-0+deb9u1.

We recommend that you upgrade your jetty9 packages.
