"It is, therefore, affected by a vulnerability as referenced in the ALAS2-2024-2460 advisory.

  - 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 this issue but has instead relied only on the application's self-reported version
number.");
