The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2021:4142 advisory.
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 jQuery versions greater than or equal to 1.0.3 and before 3.5.0, passing HTML containing <option> elements 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-2020-11023)
jquery prior to 1.9.0 allows Cross-site Scripting attacks via the load method. The load method fails to recognize and remove <script> HTML tags that contain a whitespace character, i.e: </script >, which results in the enclosed script logic to be executed. (CVE-2020-7656)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
