Electron Vulnerable to Code Execution by Re-Enabling Node.js Integration
A vulnerability has been discovered which allows Node.js integration to be re-enabled in some Electron applications that disable it.
For the application to be impacted by this vulnerability it must meet all of these conditions
- Runs on Electron 1.7, 1.8, or a 2.0.0-beta
- Allows execution of arbitrary remote code
- Disables Node.js integration
- Does not explicitly declare webviewTag: false in its webPreferences
- Does not enable the nativeWindowOption option
- Does not intercept new-window events and manually override event.newGuest without using the supplied options tag
Recommendation
Update to electron version 1.7.13, 1.8.4, or 2.0.0-beta.5 or later.
If you are unable to update your Electron version can mitigate the vulnerability with the following code.
app.on('web-contents-created', (event, win) => {
win.on('new-window', (event, newURL, frameName, disposition,
options, additionalFeatures) => {
if (!options.webPreferences) options.webPreferences = {};
options.webPreferences.nodeIntegration = false;
options.webPreferences.nodeIntegrationInWorker = false;
options.webPreferences.webviewTag = false;
delete options.webPreferences.preload;
})
})
// and *IF* you don't use WebViews at all,
// you might also want
app.on('web-contents-created', (event, win) => {
win.on('will-attach-webview', (event, webPreferences, params) => {
event.preventDefault();
})
