"It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-176 advisory.

  - The simplified implementation of blocking reads and writes introduced in Tomcat 10 and back-ported to
    Tomcat 9.0.47 onwards exposed a long standing (but extremely hard to trigger) concurrency bug in Apache
    Tomcat 10.1.0 to 10.1.0-M12, 10.0.0-M1 to 10.0.18, 9.0.0-M1 to 9.0.60 and 8.5.0 to 8.5.77 that could cause
    client connections to share an Http11Processor instance resulting in responses, or part responses, to be
    received by the wrong client. (CVE-2021-43980)

  - The JsonErrorReportValve in Apache Tomcat 8.5.83, 9.0.40 to 9.0.68 and 10.1.0-M1 to 10.1.1 did not escape
    the type, message or description values. In some circumstances these are constructed from user provided
    data and it was therefore possible for users to supply values that invalidated or manipulated the JSON
    output. (CVE-2022-45143)

  - When using the RemoteIpFilter with requests received from a reverse proxy via HTTP that include the
    X-Forwarded-Proto header set to https, session cookies created by Apache Tomcat 11.0.0-M1 to 11.0.0.-M2,
    10.1.0-M1 to 10.1.5, 9.0.0-M1 to 9.0.71 and 8.5.0 to 8.5.85 did not include the secure attribute. This
    could result in the user agent transmitting the session cookie over an insecure channel. (CVE-2023-28708)

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