In Joomla! before 3.8.4, lack of escaping in the module chromes leads to XSS vulnerabilities in the module system.

According to its self-reported version number, the detected Joomla! application is affected by multiple vulnerabilities :

 - The XSS vulnerability in module chromes as noted in the 20180101 announcement affects 3.0.0 through 3.8.3. (CVE-2018-6380)

 - The XSS vulnerability in com_fields as noted in the 20180102 announcement affects 3.7.0 through 3.8.3. (CVE-2018-6377)

 - The XSS vulnerability in Uri class as noted in the 20180103 announcement affects 1.5.0 through 3.8.3. (CVE-2018-6379)

 - The SQLi vulnerability in Hathor postinstall message as noted in the 20180103 announcement affects 1.5.0 through 3.8.3. (CVE-2018-6379)

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

According to its self-reported version number, the Joomla! installation running on the remote web server is 1.5.0 or later but prior to 3.8.4. It is, therefore, affected by multiple XSS and SQLi vulnerabilities :

  - The XSS vulnerability in module chromes as noted in the     20180101 announcement affects 3.0.0 through 3.8.3.
    (CVE-2018-6380)

  - The XSS vulnerability in com_fields as noted in the     20180102 announcement affects 3.7.0 through 3.8.3.
    (CVE-2018-6377)

  - The XSS vulnerability in Uri class as noted in the     20180103 announcement affects 1.5.0 through 3.8.3.
    (CVE-2018-6379)

  - The SQLi vulnerability in Hathor postinstall message     as noted in the 20180103 announcement affects 1.5.0     through 3.8.3. (CVE-2018-6379)

Note that Nessus has not attempted to exploit these issues but has instead relied only on the application's self-reported version number.
