CVE-ID: CVE-2024-45310

CWE-ID: CWE-362 - Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')

Exploit availability: No

Description

The vulnerability allows a remote attacker to crate empty files and directories on the host.

The vulnerability exists due to a race condition when handling containers with custom configuration. A remote attacker can trick the victim into running a specially crafted Docker or Kubernetes container, which can be used to share a volume between two containers and then exploit a race with os.MkdirAll to create empty  files or directories in arbitrary locations in the host filesystem.

Successful exploitation of the vulnerability may allow an attacker to perform a denial of service attack against the host system.

Mitigation

Install update from vendor's website.
