There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - Jenkins 2.286 and earlier, LTS 2.277.1 and earlier does not validate the type of object created after
    loading the data submitted to the `config.xml` REST API endpoint of a node, allowing attackers with
    Computer/Configure permission to replace a node with one of a different type. (CVE-2021-21639)

  - Jenkins 2.286 and earlier, LTS 2.277.1 and earlier does not properly check that a newly created view has
    an allowed name, allowing attackers with View/Create permission to create views with invalid or already-
    used names. (CVE-2021-21640)

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - Jenkins 2.286 and earlier, LTS 2.277.1 and earlier does not validate the type of object created after
    loading the data submitted to the `config.xml` REST API endpoint of a node, allowing attackers with
    Computer/Configure permission to replace a node with one of a different type. (CVE-2021-21639)

The version of Jenkins Enterprise or Jenkins Operations Center running on the remote web server is 2.222.x prior to 2.222.43.0.4, 2.249.x prior to 2.249.30.0.4, or 2.x prior to 2.277.2.3. It is, therefore, affected by multiple vulnerabilities, including the following:

  - Reflected XSS vulnerability in Micro Focus Application Automation Tools Plugin - Jenkins plugin. The     vulnerability affects all version 6.7 and earlier versions. (CVE-2021-22510)

  - Improper Certificate Validation vulnerability in Micro Focus Application Automation Tools Plugin - Jenkins     plugin. The vulnerability affects version 6.7 and earlier versions. The vulnerability could allow     unconditionally disabling of SSL/TLS certificates. (CVE-2021-22511)

  - Cross-Site Request Forgery (CSRF) vulnerability in Micro Focus Application Automation Tools Plugin -     Jenkins plugin. The vulnerability affects version 6.7 and earlier versions. The vulnerability could allow     form validation without permission checks. (CVE-2021-22512)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
