Vulnerability Title
KubeEdge: keadm DecompressTarGz path traversal enables arbitrary file write on Windows during edge node join
Source: CVE Program / CVE List V5
Vulnerability Description
KubeEdge is an open source system for extending native containerized application orchestration capabilities to hosts at Edge. From 1.16.0 until 1.21.2, 1.22.2, and 1.23.1, the DecompressTarGz function in keadm/cmd/keadm/app/cmd/util/common.go joins archive entry names to the extraction destination without sufficient validation. During keadm join or installation on Windows edge nodes, an archive influenced through a compromised, replaced, or untrusted download source can contain parent-directory components, Windows-style backslashes, absolute paths, or drive-prefixed paths that escape the intended directory. The affected keadm process can consequently write or overwrite files with its own privileges, potentially modifying configuration, executable, or service files and enabling persistent system modification or code execution. This issue is fixed in versions 1.21.2, 1.22.2, and 1.23.1.
