The remote Fedora 41 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2025-58f05c43ae advisory.

    Backport fixes for CVE-2024-6174 and CVE-2024-11584

    - cloud-init included the systemd socket unit cloud-init-hotplugd.socket with default SocketMode that     grants 0666 permissions, making it world-writable. An unprivelege user could trigger hotplug-hook commands     (CVE-2024-11584)

    - When a non-x86 platform is detected, cloud-init granted root access to a hardcoded url with a local IP     address. To prevent this, cloud-init default configurations disable platform enumeration (CVE-2024-6174)

    Note that the fix for CVE-2024-6174 includes a change that may break non-x86 OpenStack Nova users.
    Affected users may wish to use ConfigDrive as a workaround

According to the versions of the cloud-init package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

    cloud-init is an industry-standard multi-distribution method for cross-platform cloud instance     initialization by Canonical.
     There is a security vulnerability in cloud-init 25.1.2 and previous versions. The vulnerability     originates from cloud-init-hotplugd.socket#39;s default SocketMode permission is 0666, which may cause     unauthorized users to trigger commands.(CVE-2024-11584)

    cloud-init is an industry-standard multi-distribution method for cross-platform cloud instance     initialization by Canonical.
     There is a security vulnerability in cloud-init, which originates from granting root access to hardcoded     URLs during detection by non-x86 platforms.(CVE-2024-6174)

The version of cloud-init installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2024-11584 advisory.

  - cloud-init through 25.1.2 includes the systemd socket unit cloud-init-hotplugd.socket with default     SocketMode that grants 0666 permissions, making it world-writable. This is used for the /run/cloud-     init/hook-hotplug-cmd FIFO. An unprivileged user could trigger hotplug-hook commands. (CVE-2024-11584)

The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS / 24.04 LTS / 25.04 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-7677-1 advisory.

    Harry Sintonen discovered that the hotplugd socket in cloud-init was world writable. An attacker could     possibly use this issue to send hotplug-hook commands. (CVE-2024-11584)

    It was discovered that cloud-init granted root access to a hardcoded URL with a local IP address when a     non-x86 platform is detected. An attacker could possibly impersonate an OpenStack endpoint and provide     root configuration data. (CVE-2024-6174)

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

  - cloud-init through 25.1.2 includes the systemd socket unit cloud-init-hotplugd.socket with default     SocketMode that grants 0666 permissions, making it world-writable. This is used for the /run/cloud-     init/hook-hotplug-cmd FIFO. An unprivileged user could trigger hotplug-hook commands. (CVE-2024-11584)

Note that Nessus relies on the presence of the package as reported by the vendor.

The version of cloud-init installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2024-11584 advisory.
