RHEL 8 : jetty (Unpatched Vulnerability)
high Nessus Plugin ID 199245

Synopsis
The remote Red Hat 8 host is affected by multiple vulnerabilities that will not be patched.Description
The remote Redhat Enterprise Linux 8 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: local temporary directory hijacking vulnerability (CVE-2020-27216)
- jetty: buffer not correctly recycled in Gzip Request inflation (CVE-2020-27218)
- Jetty is a Java based web server and servlet engine. Prior to versions 9.4.52, 10.0.16, 11.0.16, and 12.0.1, Jetty accepts the `+` character proceeding the content-length value in a HTTP/1 header field. This is more permissive than allowed by the RFC and other servers routinely reject such requests with 400 responses. There is no known exploit scenario, but it is conceivable that request smuggling could result if jetty is used in combination with a server that does not close the connection after sending such a 400 response. Versions 9.4.52, 10.0.16, 11.0.16, and 12.0.1 contain a patch for this issue. There is no workaround as there is no known exploit scenario. (CVE-2023-40167)
Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.
