WordPress Plugin OneSignal 1.17.5 Persistent Cross-Site Scripting


Vendor: OneSignal
Product web page: https://www.onesignal.com
                  https://wordpress.org/plugins/onesignal-free-web-push-notifications/
Affected version: 1.17.5

Summary: OneSignal is a high volume and reliable push notification service
for websites and mobile applications. We support all major native and mobile
platforms by providing dedicated SDKs for each platform, a RESTful server API,
and an online dashboard for marketers to design and send push notifications.

Desc: The application suffers from an authenticated stored XSS via POST request.
The issue is triggered when input passed via the POST parameter 'subdomain' is
not properly sanitized before being returned to the user. This can be exploited
to execute arbitrary HTML and script code in a user's browser session in context
of an affected site.

Tested on: WordPress 5.2.2
           Apache/2.4.39
           PHP/7.1.30
