7.8High

Attack vector: Local
Complexity: Low
Privileges needed: None
User interaction: Required
Impact: Full C/I/A compromise
Weakness: CWE-78

Impact

Attackers can execute arbitrary OS commands as the local user running buildebooks. To exploit it, they must trick a user into processing a malicious book project with a crafted filename or folder name and kindle enabled.

Root cause

The package passes unsanitized EPUB filenames directly to kindlegen using child_process.exec in lib/kindle.js.

Affected systems

buildebooks versions prior to 0.2.2

CVSS v3.1 · CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H

Fix & remediation

Upgrade buildebooks to version 0.2.2 or later. If upgrading must wait, avoid building untrusted book projects or disable the kindle option ('kindle: false') in your project configurations.

shell

$ npm install -g buildebooks@latest

NVD description

buildebooks before 0.2.2 contains an OS command injection vulnerability in lib/kindle.js that allows attackers to execute commands by supplying a crafted EPUB file name passed to kindlegen via child_process.exec. Attackers can craft a book project with a malicious front-matter filename or project folder name and kindle: true to execute OS commands as the user running buildebooks.
