CVE-2019-17221

关于

PhantomJS uses internal module: webpage, to open, close, render, and perform multiple actions on webpages, which suffers from an arbitrary file read vulnerability. The vulnerability exists in the page.open() function of the webpage module, which loads the specified URL and calls a given callback. When opening a HTML file, an attacker can supply specially crafted file content, which allows reading arbitrary files on the filesystem. The vulnerability is demonstrated by using page.render() as the function callback, resulting in the generation of a PDF or an image of the targeted file.
