CVE-2017-12581· NVD / CVE Program· CNA mitre

GitHub Electron before 1.6.8 allows remote command execution because of a nodeIntegration bypass vulnerability.

GitHub Electron before 1.6.8 allows remote command execution because of a nodeIntegration bypass vulnerability. This also affects all applications that bundle Electron code equivalent to 1.6.8 or earlier. Bypassing the Same Origin Policy (SOP) is a precondition; however, recent Electron versions do not have strict SOP enforcement. Combining an SOP bypass with a privileged URL internally used by Electron, it was possible to execute native Node.js primitives in order to run OS commands on the user's host. Specifically, a chrome-devtools://devtools/bundled/inspector.html window could be used to eval a Node.js child_process.execFile API call.

Exploit status

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Research context

For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.

Root cause

User input is inserted as text into a shell command. The shell may interpret special characters in the input as part of the command.

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

Vulnerable

Fixed

ts
const host = req.body.host;if (!/^[a-z0-9.-]{1,253}$/i.test(host)) return res.sendStatus(400);execFile("ping", ["-c", "1", host], onResult);
