Synopsis

Jetty < 9.4.21 Multiple Vulnerabilities

Description

According to its self-reported version number, the instance of Jetty hosted on the remote web server is prior to < 9.4.21. It is, therefore, affected by multiple vulnerabilities:

 - Some HTTP/2 implementations are vulnerable to a flood of empty frames, potentially leading to a denial of service. (CVE-2019-9518)

 - Some HTTP/2 implementations are vulnerable to a header leak, potentially leading to a denial of service. (CVE-2019-9516)

 - Some HTTP/2 implementations are vulnerable to a settings flood, potentially leading to a denial of service. (CVE-2019-9515)

 - Some HTTP/2 implementations are vulnerable to a reset flood, potentially leading to a denial of service. (CVE-2019-9514)

 - Some HTTP/2 implementations are vulnerable to ping floods, potentially leading to a denial of service. (CVE-2019-9512)

 - Some HTTP/2 implementations are vulnerable to window size manipulation and stream prioritization manipulation, potentially leading to a denial of service. (CVE-2019-9511)

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 9.4.21 or later.
