Remote Mouse App for Android and iOS has been detected with as many as six zero-day flaws. These may lead bad actors to gain access to execute code without user interaction.

According to security researcher Axel Persinger, the Remote Mouse App has a collection of flaws aptly called ‘Mouse Trap’. The application is vulnerable and puts users at risk with a bad authentication mechanism, lack of encryption, and poor default configuration.

Remote mouse App for Android and iOS is a popular app used to transform your mobile or tablet into a multifunction device i.e. wireless mouse, keyboard, and trackpad for computers.

According to Persinger, he reported the flaws to Remote Mouse on Feb. 6, 2021. Though he never received any response from Remote Mouse. This forced him to disclose the bugs publicly after following the 90-day disclosure deadline. Let’s hope Remote Mouse takes note of the numerous flaws and gets them fixed ASAP.
