According to its self-reported version, the version of Pulse Connect Secure running on the remote host is prior to 9.1R9. It is, therefore, affected by multiple 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.
