In Dogtag PKI through 10.8.3, the pki.client.PKIConnection class did not enable python-requests certificate validation. Since the verify parameter was hard-coded in all request functions, it was not possible to override the setting. As a result, tools making use of this class, such as the pki-server command, may have been vulnerable to Person-in-the-Middle attacks in certain non-localhost use cases. This is fixed in 10.9.0-b1.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

The remote Oracle Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2020-4847 advisory.

  - 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-container property of tooltip. (CVE-2018-14042)

  - 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 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)

  - 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)

  - A Reflected Cross Site Scripting flaw was found in all pki-core 10.x.x versions module from the pki-core     server due to the CA Agent Service not properly sanitizing the certificate request page. An attacker could     inject a specially crafted value that will be executed on the victim's browser. (CVE-2019-10146)

  - A vulnerability was found in all pki-core 10.x.x versions, where the Key Recovery Authority (KRA) Agent     Service did not properly sanitize recovery request search page, enabling a Reflected Cross Site Scripting     (XSS) vulnerability. An attacker could trick an authenticated victim into executing specially crafted     Javascript code. (CVE-2019-10179)

  - A Reflected Cross Site Scripting vulnerability was found in all pki-core 10.x.x versions, where the pki-ca     module from the pki-core server. This flaw is caused by missing sanitization of the GET URL parameters. An     attacker could abuse this flaw to trick an authenticated user into clicking a specially crafted link which     can execute arbitrary code when viewed in a browser. (CVE-2019-10221)

  - A flaw was found in the Key Recovery Authority (KRA) Agent Service in pki-core 10.10.5 where it did not     properly sanitize the recovery ID during a key recovery request, enabling a reflected cross-site scripting     (XSS) vulnerability. An attacker could trick an authenticated victim into executing specially crafted     Javascript code. (CVE-2020-1721)

  - 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.
