New 0-Day Flaw Affecting Most Android Phones Being Exploited in the Wild
Another day, another revelation of a critical unpatched zero-day vulnerability, this time in the world's most widely used mobile operating system, Android. What's more? The Android zero-day vulnerability has also been found to be exploited in the wild by the Israeli surveillance vendor NSO Group—infamous for selling zero-day exploits to governments—or one of its customers, to gain control of their targets' Android devices.
Discovered by Project Zero researcher Maddie Stone, the details and a proof-of-concept exploit for the high-severity security vulnerability, tracked as CVE-2019-2215, has been made public today—just seven days after reporting it to the Android security team.
According to the researcher, since the issue is "accessible from inside the Chrome sandbox," the Android kernel zero-day vulnerability can also be exploited remotely by combining it with a separate Chrome rendering flaw. "The bug is a local privilege escalation vulnerability that allows for a full compromise of a vulnerable device. If the exploit is delivered via the Web, it only needs to be paired with a renderer exploit, as this vulnerability is accessible through the sandbox," Stone says in the Chromium blog.
