[CVE-2020-6831] Exploiting Android Messengers with WebRTC: Part 2

WebRTC is an open source video conferencing solution used by a variety of software including browsers, messaging clients and streaming services. While Project Zero has reported several vulnerabilities in WebRTC in the past, it was not clear whether these bugs were exploitable, especially outside of browsers. I investigated whether two recent bugs are exploitable in popular Android messaging applications.

This three-part series highlights the technical challenges involved in finding and exploiting JavaScript engine vulnerabilities in modern web browsers and evaluates current exploit mitigation technologies. The exploited vulnerability, CVE-2020-9802, was fixed in iOS 13.5, while two of the mitigation bypasses, CVE-2020-9870 and CVE-2020-9910, were fixed in iOS 13.6.

On October 3, 2019, we disclosed issue 1942 (CVE-2019-2215), which is a use-after-free in Binder in the Android kernel. The bug is a local privilege escalation vulnerability that allows for a full compromise of a vulnerable device. If chained with a browser renderer exploit, this bug could fully compromise a device through a malicious website.
