Description

Cloud Commander (cloudcmd) versions 19.20.2 through 19.21.1 contains a path traversal vulnerability in the GET /api/v1/pack endpoint where the onGET handler at server/rest/index.js:130 calls the unguarded root() function instead of the root.resolve() validation wrapper used elsewhere. Attackers can send percent-encoded directory traversal sequences in the pack request path to read arbitrary files outside the configured --root directory, such as /etc/passwd or SSH private keys, which are archived and streamed back as a downloadable tar.gz file.
