Docker Engine 26.0.0 < 26.0.2 Unexpected Resource Exposure

medium Nessus Plugin ID 193911

Language:

Synopsis

The remote host has an application installed that is affected by an unexpected resource exposure vulnerability.

Description

The version of the Docker Engine installed on the remote host is 26.0.x prior to 26.0.2. It is therefore affected by an unexpected resource exposure vulnerability. In the affected versions of Moby, an open source container framework that is a key component of Docker Engine, Docker Desktop, and other distributions of container tooling or runtimes, IPv6 is not disabled on network interfaces, including those belonging to networks where `--ipv6=false`. A container with an `ipvlan` or `macvlan` interface will normally be configured to share an external network link with the host machine.
Because of this direct access, (1) Containers may be able to communicate with other hosts on the local network over link-local IPv6 addresses, (2) if router advertisements are being broadcast over the local network, containers may get SLAAC-assigned addresses, and (3) the interface will be a member of IPv6 multicast groups. This means interfaces in IPv4-only networks present an unexpectedly and unnecessarily increased attack surface.

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 26.0.2 or later
