Pulse Connect Secure < 9.1R9 (SA44601)

high Nessus Plugin ID 142058


New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote device is affected by multiple vulnerabilities.


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.


Upgrade to Pulse Connect Secure version 9.1R9 or later.
