Docker Engine < 29.5.1 Arbitrary Code Execution

high Nessus Plugin ID 324948

Synopsis

The remote host has an application installed that is affected by an arbitrary code execution vulnerability.

Description

The version of the Docker Engine (Moby) installed on the remote host is prior to 29.5.1. It is, therefore, affected by an arbitrary code execution vulnerability:

- When a compressed archive is uploaded to a container via PUT /containers/{id}/archive or piped through docker cp -, the daemon resolves decompression binaries (such as xz or unpigz) from the container's filesystem rather than the host's due to incorrect ordering of operations. A malicious container image containing a trojanized decompression binary can achieve arbitrary code execution with full daemon privileges, including host root UID and unrestricted capabilities, when a user uploads a compressed (xz or gzip) archive into that container.
(CVE-2026-41567)

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

Solution

Upgrade to Docker Engine version 29.5.1 or later.
