The vulnerability stems from the direct joining of archive entry names with the target destination path without sufficient validation. An attacker capable of providing a malicious \u003ccode\u003e.tar.gz\u003c/code\u003e archive can leverage path traversal components, Windows-style backslashes, absolute paths, or drive-prefixed paths to write or overwrite files outside the intended destination directory.\u003c/p\u003e\n\u003cp\u003eThis vulnerability (CVE-2026-62369) specifically impacts Windows environments where \u003ccode\u003ekeadm\u003c/code\u003e extracts component archives. Depending on the privileges of the user executing the \u003ccode\u003ekeadm\u003c/code\u003e command, an attacker can modify critical system files, including configuration files, executables, or service-related artifacts. Successful exploitation could lead to persistent system modification or unauthorized code execution. Mitigation requires upgrading to KubeEdge v1.21.2, v1.22.2, or v1.23.1, or ensuring that only trusted KubeEdge component archives are used during installation.\u003c/p\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eThe vulnerability allows an attacker to bypass directory constraints during archive extraction on Windows hosts. Depending on the targeted file, this can result in privilege escalation, system persistence, or full compromise of the affected edge node. This is particularly critical for administrative users or service accounts running \u003ccode\u003ekeadm\u003c/code\u003e with high-privilege context on Windows edge infrastructure.\u003c/p\u003e\n\u003ch2 id=\"recommendation\"\u003eRecommendation\u003c/h2\u003e\n\u003cul\u003e\n\u003cli\u003eUpgrade KubeEdge to versions 1.21.2, 1.22.2, or 1.23.1 or later to implement secure file path validation in \u003ccode\u003eDecompressTarGz\u003c/code\u003e.\u003c/li\u003e\n\u003cli\u003eEnforce strict supply chain controls by only utilizing official and verified KubeEdge package sources.\u003c/li\u003e\n\u003cli\u003eRestrict write permissions and administrative privileges for the service account or user executing the \u003ccode\u003ekeadm\u003c/code\u003e join process.\u003c/li\u003e\n\u003cli\u003eImplement integrity verification for all downloaded archives prior to triggering the \u003ccode\u003ekeadm\u003c/code\u003e extraction routines.\u003c/li\u003e\n\u003c/ul\u003e\n","date_modified":"2026-09-23T01:55:26Z","date_published":"2026-09-23T01:55:26Z","id":"https://feed.craftedsignal.io/briefs/2026-09-kubeedge-path-traversal/","summary":"KubeEdge keadm utility contains a path traversal vulnerability (CVE-2026-62369) in its archive extraction function, allowing an attacker to overwrite arbitrary files on Windows systems during edge node join or installation.","title":"KubeEdge keadm Arbitrary File Write via Path Traversal","url":"https://feed.craftedsignal.io/briefs/2026-09-kubeedge-path-traversal/"}],"language":"en","title":"CraftedSignal Threat Feed - Keadm (\u003e= 1.22.0, \u003c 1.22.2)","version":"https://jsonfeed.org/version/1.1"}
