The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2021:4801 advisory.

    Red Hat OpenShift Container Platform is Red Hat's cloud computing     Kubernetes application platform solution designed for on-premise or private     cloud deployments.

    This advisory contains the RPM packages for Red Hat OpenShift Container     Platform 4.7.38. See the following advisory for the container images for     this release:

    https://access.redhat.com/errata/RHBA-2021:4802

    All OpenShift Container Platform 4.7 users are advised to upgrade to these     updated packages and images when they are available in the appropriate     release channel. To check for available updates, use the OpenShift Console     or the CLI oc command. Instructions for upgrading a cluster are available     at     https://docs.openshift.com/container-platform/4.7/updating/updating-cluster-between-     minor.html#understanding-upgrade-channels_updating-cluster-between-minor     Security Fix(es):

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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 2.277.x prior to 2.277.43.0.2, or 2.x prior to 2.303.3.3. It is, therefore, affected by multiple vulnerabilities, including the following:

  - Agent processes are able to completely bypass file path filtering by wrapping the file operation in an     agent file path in Jenkins 2.318 and earlier, LTS 2.303.2 and earlier. (CVE-2021-21690)

  - Creating symbolic links is possible without the 'symlink' agent-to-controller access control permission in     Jenkins 2.318 and earlier, LTS 2.303.2 and earlier. (CVE-2021-21691)

  - FilePath#renameTo and FilePath#moveAllChildrenTo in Jenkins 2.318 and earlier, LTS 2.303.2 and earlier     only check 'read' agent-to-controller access permission on the source path, instead of 'delete'.
    (CVE-2021-21692)

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

According to its its self-reported version number, the version of Jenkins running on the remote web server is Jenkins LTS prior to 2.303.3 or Jenkins weekly prior to 2.319. It is, therefore, affected by multiple vulnerabilities:

  - Jenkins 2.318 and earlier, LTS 2.303.2 and earlier does not check agent-to-controller access to create     parent directories in FilePath#mkdirs. (CVE-2021-21685)

  - File path filters in the agent-to-controller security subsystem of Jenkins 2.318 and earlier, LTS 2.303.2     and earlier do not canonicalize paths, allowing operations to follow symbolic links to outside allowed     directories. (CVE-2021-21686)

  - Jenkins 2.318 and earlier, LTS 2.303.2 and earlier does not check agent-to-controller access to create     symbolic links when unarchiving a symbolic link in FilePath#untar. (CVE-2021-21687)

  - The agent-to-controller security check FilePath#reading(FileVisitor) in Jenkins 2.318 and earlier, LTS     2.303.2 and earlier does not reject any operations, allowing users to have unrestricted read access using     certain operations (creating archives, FilePath#copyRecursiveTo). (CVE-2021-21688)

  - FilePath#unzip and FilePath#untar were not subject to any agent-to-controller access control in Jenkins     2.318 and earlier, LTS 2.303.2 and earlier. (CVE-2021-21689)

  - Agent processes are able to completely bypass file path filtering by wrapping the file operation in an     agent file path in Jenkins 2.318 and earlier, LTS 2.303.2 and earlier. (CVE-2021-21690)

  - Creating symbolic links is possible without the 'symlink' agent-to-controller access control permission in     Jenkins 2.318 and earlier, LTS 2.303.2 and earlier. (CVE-2021-21691)

  - FilePath#renameTo and FilePath#moveAllChildrenTo in Jenkins 2.318 and earlier, LTS 2.303.2 and earlier     only check 'read' agent-to-controller access permission on the source path, instead of 'delete'.
    (CVE-2021-21692)

  - When creating temporary files, agent-to-controller access to create those files is only checked after     they've been created in Jenkins 2.318 and earlier, LTS 2.303.2 and earlier. (CVE-2021-21693)

  - FilePath#toURI, FilePath#hasSymlink, FilePath#absolutize, FilePath#isDescendant, and     FilePath#get*DiskSpace do not check any permissions in Jenkins 2.318 and earlier, LTS 2.303.2 and earlier.
    (CVE-2021-21694)

  - FilePath#listFiles lists files outside directories that agents are allowed to access when following     symbolic links in Jenkins 2.318 and earlier, LTS 2.303.2 and earlier. (CVE-2021-21695)

  - Jenkins 2.318 and earlier, LTS 2.303.2 and earlier does not limit agent read/write access to the libs/     directory inside build directories when using the FilePath APIs, allowing attackers in control of agent     processes to replace the code of a trusted library with a modified variant. This results in unsandboxed     code execution in the Jenkins controller process. (CVE-2021-21696)

  - Jenkins 2.318 and earlier, LTS 2.303.2 and earlier allows any agent to read and write the contents of any     build directory stored in Jenkins with very few restrictions. (CVE-2021-21697)

  - Jenkins Subversion Plugin 2.15.0 and earlier does not restrict the name of a file when looking up a     subversion key file on the controller from an agent. (CVE-2021-21698)

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