Docker Desktop: Improper Restriction of Communication Channel to Intended Endpoints
CVE-2024-6222 is a high-severity improper restriction of communication channel to intended endpoints vulnerability in Docker Desktop from Docker, with a CVSS 3.1 base score of 7.0 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user. The record lists version v4.29.0 as the first without the flaw, so updating Docker Desktop to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.56% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Docker Desktop to v4.29.0 or a later version.
- Update desktop to 4.29.0 or a later version.
Affected products and versions
| Vendor | Product | Affected versions | Fixed in |
|---|---|---|---|
| Docker | Docker Desktop | before v4.29.0 | v4.29.0 |
| Docker | desktop | before 4.29.0 | 4.29.0 |

Official description
In Docker Desktop before v4.29.0, an attacker who has gained access to the Docker Desktop VM through a container breakout can further escape to the host by passing extensions and dashboard related IPC messages. Docker Desktop v4.29.0 https://docs.docker.com/desktop/release-notes/#4290 fixes the issue on MacOS, Linux and Windows with Hyper-V backend. As exploitation requires "Allow only extensions distributed through the Docker Marketplace" to be disabled, Docker Desktop v4.31.0 https://docs.docker.com/desktop/release-notes/#4310 additionally changes the default configuration to enable this setting by default.

The underlying weakness: Improper Restriction of Communication Channel to Intended Endpoints
