"According to its self-reported version, the instance of Joomla! running on the remote web server is 4.0.x prior to
4.2.7. It is, therefore, affected by multiple vulnerabilities.

  - An issue was discovered in Joomla! 4.0.0 through 4.2.6. A missing token check causes a CSRF vulnerability
    in the handling of post-installation messages. (CVE-2023-23750)

  - An issue was discovered in Joomla! 4.0.0 through 4.2.4. A missing ACL check allows non super-admin users
    to access com_actionlogs. (CVE-2023-23751)

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