"The version of Tomcat installed on the remote host is prior to 9.0.83. It is, therefore, affected by a vulnerability as
referenced in the fixed_in_apache_tomcat_9.0.83_security-9 advisory.

  - Improper Input Validation vulnerability in Apache Tomcat.Tomcat from 11.0.0-M1 through 11.0.0-M10, from
    10.1.0-M1 through 10.1.15, from 9.0.0-M1 through 9.0.82 and from 8.5.0 through 8.5.95 did not correctly
    parse HTTP trailer headers. A trailer header that exceeded the header size limit could cause Tomcat to
    treat a single request as multiple requests leading to the possibility of request smuggling when behind a
    reverse proxy. Users are recommended to upgrade to version 11.0.0-M11 onwards, 10.1.16 onwards, 9.0.83
    onwards or 8.5.96 onwards, which fix the issue. (CVE-2023-46589)

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