Synopsis

Jetty 11.0.x < 11.0.2 Multiple Vulnerabilities

Description

According to its self-reported version number, the instance of Jetty hosted on the remote web server is prior to 9.4.39, 10.0.x prior to 10.0.2 or 11.0.x prior to 11.0.2. It is, therefore, affected by multiple vulnerabilities:

- An issue where CPU usage can reach 100% with a large invalid TLS frame. (CVE-2021-28165)

- A issue with permitting access to protected resources within the WEB-INF directory when accessed with encoded paths. (CVE-2021-28164)

- An issue when a symlinked webapps directory is used, the contents of the webapps directory is deployed as a static webapp. (CVE-2021-28163)

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Jetty version 11.0.2 or later.
