CVE-2024-32473
Description
A flaw was found in Moby, an open source container framework that is a key component of Docker Engine, Docker Desktop, and other distributions of container tooling and runtimes. In certain versions, 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, and because of this direct access, containers may be able to communicate with other hosts on the local network over link-local IPv6 addresses. Additionally, if router advertisements are being broadcast over the local network, containers may get SLAAC-assigned addresses and the interface will be a member of IPv6 multicast groups. This means interfaces IPv4-only networks present an unexpectedly and unnecessarily increased attack surface
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.

Understanding the Weakness (CWE)
Confidentiality
Technical Impact: Read Application Data
An adversary that gains access to a resource exposed to a wrong sphere could potentially retrieve private data from that resource, thus breaking the intended confidentiality of that data.
Integrity
Technical Impact: Modify Application Data
An adversary that gains access to a resource exposed to a wrong sphere could potentially modify data held within that resource, thus breaking the intended integrity of that data and causing the system relying on that resource to make unintended decisions.
Other
Technical Impact: Varies by Context
The consequences may vary widely depending on how the product uses the affected resource.
