CVE-2024-41110
CVSS v3.1
9.9
Critical
| Vector | AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions:
Docker Engine versions prior to v27.1.1
Docker Engine versions 19.03 and later, excluding v19.03.x
Docker CE versions prior to v27.1.1
Description:
A security vulnerability has been detected in certain versions of Docker Engine, which could allow an attacker to bypass authorization plugins (AuthZ) under specific circumstances. The base likelihood of this being exploited is low. Using a specially-crafted API request, an Engine API client could make the daemon forward the request or response to an authorization plugin without the body. In certain circumstances, the authorization plugin may allow a request which it would have otherwise denied if the body had been forwarded to it. A security issue was discovered in 2018, where an attacker could bypass AuthZ plugins using a specially crafted API request. This could lead to unauthorized actions, including privilege escalation. Although this issue was fixed in Docker Engine v18.09.1 in January 2019, the fix was not carried forward to later major versions, resulting in a regression.
Recommendations:
For Docker Engine versions prior to v27.1.1, update to version v27.1.1 or later to fix the vulnerability.
For Docker Engine versions 19.03 and later, excluding v19.03.x, update to a version that includes the merged patches, such as the master, 19.03, 20.0, 23.0, 24.0, 25.0, 26.0, or 26.1 release branches.
If one is unable to upgrade immediately, avoid using AuthZ plugins and/or restrict access to the Docker API to trusted parties, following the principle of least privilege.
