GHSA-48Q5-W887-33WV Incus has a restricted project bypass leading to arbitrary command execution

Summary Instance snapshots ignore the restricted.containers.lowlevel=block setting; allowing for arbitrary command execution on the Incus server by abusing lowlevel hooks such as raw.lxc and raw.qemu. Details Instance snapshots ignore the restricted.containers.lowlevel=block setting; allowing for...

Missing Authorization

Overview Affected versions of this package are vulnerable to Missing Authorization through the raw.lxc and raw.qemu hooks when the restricted.containers.lowlevel=block setting is ignored during instance snapshot restoration. An attacker can execute arbitrary commands with root privileges on the...

Incus has an arbitrary file write on host via `exec-output` symlink in crafted image

Summary The record-output parameter of the /instances/$name/exec endpoint stores the output of the command in the exec-output directory of the instance. If exec-output is a symlink, file named execUUID.stdout and execUUID.stderr can be written to an arbitrary location where the .stdout file will...

External Control of File Name or Path

Overview Affected versions of this package are vulnerable to External Control of File Name or Path through the rootfs symlink during image extraction. An attacker can gain unauthorized access to sensitive files and perform arbitrary file creation or modification on the host by importing a special...

Incus has an arbitrary file read+write on host via rootfs/ symlink in malicious image

Summary A specially crafted image can be used to read or create/write arbitrary files on the host; possibly leading to arbitrary command execution. Details Incus validates an image as soon as it sees a normal metadata.yaml and a rootfs/ entry, but full extraction can later process a duplicate...
