"The version of tested product installed on the remote host is prior to tested version. It is, therefore, affected by
multiple vulnerabilities as referenced in the ALAS2-2020-1519 advisory.

  - jQuery before 3.0.0 is vulnerable to Cross-site Scripting (XSS) attacks when a cross-domain Ajax request
    is performed without the dataType option, causing text/javascript responses to be executed.
    (CVE-2015-9251)

  - In Bootstrap 3.x before 3.4.0 and 4.x-beta before 4.0.0-beta.2, XSS is possible in the data-target
    attribute, a different vulnerability than CVE-2018-14041. (CVE-2016-10735)

  - In Bootstrap before 4.1.2, XSS is possible in the collapse data-parent attribute. (CVE-2018-14040)

  - In Bootstrap before 4.1.2, XSS is possible in the data-target property of scrollspy. (CVE-2018-14041)

  - In Bootstrap before 4.1.2, XSS is possible in the data-container property of tooltip. (CVE-2018-14042)

  - In Bootstrap before 3.4.0, XSS is possible in the tooltip data-viewport attribute. (CVE-2018-20676)

  - In Bootstrap before 3.4.0, XSS is possible in the affix configuration target property. (CVE-2018-20677)

  - jQuery before 3.4.0, as used in Drupal, Backdrop CMS, and other products, mishandles jQuery.extend(true,
    {}, ...) because of Object.prototype pollution. If an unsanitized source object contained an enumerable
    __proto__ property, it could extend the native Object.prototype. (CVE-2019-11358)

  - In Bootstrap before 3.4.1 and 4.3.x before 4.3.1, XSS is possible in the tooltip or popover data-template
    attribute. (CVE-2019-8331)

  - In jQuery versions greater than or equal to 1.2 and before 3.5.0, passing HTML from untrusted sources -
    even after sanitizing it - to one of jQuery's DOM manipulation methods (i.e. .html(), .append(), and
    others) may execute untrusted code. This problem is patched in jQuery 3.5.0. (CVE-2020-11022)

  - A flaw was found in all ipa versions 4.x.x through 4.8.0. When sending a very long password (>= 1,000,000
    characters) to the server, the password hashing process could exhaust memory and CPU leading to a denial
    of service and the website becoming unresponsive. The highest threat from this vulnerability is to system
    availability. (CVE-2020-1722)

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