changedetection.io Path Traversal vulnerability

changedetection.io is free, open source web page change detection software. Prior to version 0.47.5, when a WebDriver is used to fetch files, `source:file:///etc/passwd` can be used to retrieve local system files, where the more traditional `file:///etc/passwd` gets blocked. Version 0.47.5 fixes the issue.

Root cause

A user-supplied file name is joined with the allowed directory, but the result is never checked to confirm it is still inside that directory.

The bug in code

The whole CWE-22 class

A representative example of this vulnerability class. Not the vendor's source code; it shows the faulty pattern and its fix.

Vulnerable

ts
const file = path.join(ROOT, req.query.name);res.sendFile(file);

Fixed

ts
const file = path.resolve(ROOT, req.query.name);if (!file.startsWith(ROOT + path.sep)) {  return res.sendStatus(400);}res.sendFile(file);
