According to its self-reported version, the instance of Joomla! running on the remote web server is 3.0.x prior to 3.9.24. It is, therefore, affected by multiple vulnerabilities.
An issue was discovered in Joomla! 3.0.0 through 3.9.23. The lack of ACL checks in the orderPosition endpoint of com_modules leak names of unpublished and/or inaccessible modules. (CVE-2021-23123)
An issue was discovered in Joomla! 3.9.0 through 3.9.23. The lack of escaping in mod_breadcrumbs aria- label attribute allows XSS attacks. (CVE-2021-23124)
An issue was discovered in Joomla! 3.1.0 through 3.9.23. The lack of escaping of image-related parameters in multiple com_tags views cause lead to XSS attack vectors. (CVE-2021-23125)
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
