Three Android applications that allow users to use devices as remote keyboards for their computers have critical vulnerabilities that could expose key presses and enable remote code execution.
CVE-2022-45479 - PC Keyboard flow allowing a remote unauthenticated user to send instructions to the server to execute arbitrary code without requiring authorization or authentication.
CVE-2022-45480 - PC Keyboard flaw allowing an attacker to perform a man-in-the-middle attack and read all keypresses in cleartext.
CVE-2022-45481 - Lack of password requirement in the default configuration of Lazy Mouse, allowing remote unauthenticated users to execute arbitrary code without requiring authorization or authentication.
Successful exploitation could also enable remote attackers run arbitrary code on the device.
If you're looking for a remote keyboard app, there are several actively maintained projects on Google Play, many of which have positive user ratings.
