"The AlmaLinux 9.2 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare
ALMALINUX9.2:CLSA-2025:1739387851 advisory.

  - 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. Older, EOL versions may also be
    affected. The vulnerability is limited to the ROOT (default) web application. (CVE-2023-41080)

  - Incomplete Cleanup vulnerability in Apache Tomcat. The internal fork of Commons FileUpload packaged with
    Apache Tomcat 9.0.70 through 9.0.80 and 8.5.85 through 8.5.93 included an unreleased, in progress
    refactoring that exposed a potential denial of service on Windows if a web application opened a stream for
    an uploaded file but failed to close the stream. The file would never be deleted from disk creating the
    possibility of an eventual denial of service due to the disk being full. Other, EOL versions may also be
    affected. Users are recommended to upgrade to version 9.0.81 onwards or 8.5.94 onwards, which fixes the
    issue. (CVE-2023-42794)

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