CVE-2024-5321

Log disclosure and tampering via permissive ACLs

Published Jul 18, 2024 · Updated Sep 13, 2024

Incorrect file permissions in affected Kubernetes kubelet releases allow local users to read or modify Windows container logs. The pkg/util/filesystem code fails to set restrictive Windows ACLs on container log files, leaving read access to BUILTIN\Users and write access to NT AUTHORITY\Authenticated Users. Exploitation requires a local account on a Windows node; it exposes log contents and permits tampering without interrupting workloads.
