"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 3.9.5. It is, therefore, affected by multiple vulnerabilities:

  - A directory traversal vulnerability exists in versions 1.5.0 to 3.9.4 within the Media Manager component 
    due to improperly sanitizing the folder parameter. An authenticated, remote attacker can exploit this, by
    sending a URI that contains directory traversal characters, to disclose the contents of files located
    outside of the server's restricted path. (CVE-2019-10945)

  - An access control limit bypass exists in versions 3.2.0 to 3.9.4 within the gethelpsites() function of the
    com_users component. An unauthenticated, remote attacker can exploit this and access the 'refresh list of
    helpsites' endpoint. (CVE-2019-10946)

 - A cross-site scripting (XSS) vulnerability exists in versions 3.0.0 to 3.9.4 due to improper validation of
   user-supplied input before returning it to users. An unauthenticated, remote attacker can exploit this, by
   convincing a user to click a specially crafted URL, to execute arbitrary script code in a user's browser
   session.


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