"The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the
dla-3617 advisory.

  - Apache Commons FileUpload before 1.5 does not limit the number of request parts to be processed resulting
    in the possibility of an attacker triggering a DoS with a malicious upload or series of uploads. Note
    that, like all of the file upload limits, the new configuration option (FileUploadBase#setFileCountMax) is
    not enabled by default and must be explicitly configured. (CVE-2023-24998)

  - URL Redirection to Untrusted Site ('Open Redirect') vulnerability in FORM authentication feature Apache
    Tomcat.This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.0-M10, from 10.1.0-M1 through
    10.0.12, from 9.0.0-M1 through 9.0.79 and from 8.5.0 through 8.5.92. The vulnerability is limited to the
    ROOT (default) web application. (CVE-2023-41080)

  - Incomplete Cleanup vulnerability in Apache Tomcat.When recycling various internal objects in Apache Tomcat
    from 11.0.0-M1 through 11.0.0-M11, from 10.1.0-M1 through 10.1.13, from 9.0.0-M1 through 9.0.80 and from
    8.5.0 through 8.5.93, an error could cause Tomcat to skip some parts of the recycling process leading to
    information leaking from the current request/response to the next. Users are recommended to upgrade to
    version 11.0.0-M12 onwards, 10.1.14 onwards, 9.0.81 onwards or 8.5.94 onwards, which fixes the issue.
    (CVE-2023-42795)

  - The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation
    can reset many streams quickly, as exploited in the wild in August through October 2023. (CVE-2023-44487)

  - Improper Input Validation vulnerability in Apache Tomcat.Tomcat from 11.0.0-M1 through 11.0.0-M11, from
    10.1.0-M1 through 10.1.13, from 9.0.0-M1 through 9.0.81 and from 8.5.0 through 8.5.93 did not correctly
    parse HTTP trailer headers. A specially crafted, invalid trailer header 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-M12 onwards, 10.1.14 onwards, 9.0.81 onwards or
    8.5.94 onwards, which fix the issue. (CVE-2023-45648)

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