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.

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)
