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

  - An incorrect permission check in Jenkins Matrix Authorization Strategy Plugin 2.6.5 and earlier allows
    attackers with Item/Read permission on nested items to access them, even if they lack Item/Read permission
    for parent folders. (CVE-2021-21623)

The remote Red Hat Enterprise Linux CoreOS 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2021:2437 advisory.

  - golang: crypto/elliptic: incorrect operations on the P-224 curve (CVE-2021-3114)

  - gogo/protobuf: plugin/unmarshal/unmarshal.go lacks certain index validation (CVE-2021-3121)

  - openshift: Injected service-ca.crt incorrectly contains additional internal CAs (CVE-2021-3636)

  - python-eventlet: improper handling of highly compressed data and memory allocation with excessive size     allows DoS (CVE-2021-21419)

  - jenkins-2-plugins/matrix-auth: Incorrect permission checks in Matrix Authorization Strategy Plugin     (CVE-2021-21623)

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

The version of Jenkins Enterprise or Jenkins Operations Center running on the remote web server is 2.222.x prior to 2.222.43.0.3 rev2, 2.249.x prior to 2.249.30.0.3 rev2, or 2.x prior to 2.277.1.2 rev2. It is, therefore, affected by multiple vulnerabilities, including the following:

  - An incorrect permission check in Jenkins Matrix Authorization Strategy Plugin 2.6.5 and earlier allows     attackers with Item/Read permission on nested items to access them, even if they lack Item/Read permission     for parent folders. (CVE-2021-21623)

  - An incorrect permission check in Jenkins Role-based Authorization Strategy Plugin 3.1 and earlier allows     attackers with Item/Read permission on nested items to access them, even if they lack Item/Read permission     for parent folders. (CVE-2021-21624)

  - A cross-site request forgery (CSRF) vulnerability in Jenkins Libvirt Agents Plugin 1.9.0 and earlier     allows attackers to stop hypervisor domains. (CVE-2021-21627)

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