"According to its self-reported version, the version of Pulse Policy Secure running on the remote host is prior to
9.1R9. It is, therefore, affected by the following vulnerabilities:

  - A vulnerability in the Pulse Connect Secure < 9.1R9 admin web interface could allow an authenticated
    attacker to perform an arbitrary code execution using uncontrolled gzip extraction. (CVE-2020-8260)

  - A vulnerability in the Pulse Connect Secure / Pulse Policy Secure < 9.1R9 is vulnerable to arbitrary
    cookie injection. (CVE-2020-8261)

  - 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)

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