Remote Mouse App Crippled With ‘Mouse Trap’ Zero-Day Bugs

Remote Mouse mobile app has some serious security flaws that it hasn’t addressed yet. A researcher found six zero-day bugs in the Remote Mouse app he named “Mouse Trap”. Exploiting the vulnerabilities allows remote code execution.

Remote Mouse App Bugs

Security researcher Axel Persinger has shared details of the zero-day bugs in the Remote Mouse app in his post.

Remote Mouse is a dedicated mobile application that transforms the mobile device into a virtual mouse, keyboard, or trackpad.

As it turns out, the researcher found six different zero-day bugs in the app that currently boasts over 10,000,000 installs on Google Play Store. That means these bugs – yet unpatched – put thousands of users at risk.

Describing the risk associated with this app, the researcher stated,

It’s clear that this application is very vulnerable and puts users at risk with bad authentication mechanisms, lack of encryption, and poor default configuration.

Briefly, the researcher found the following six bugs in the app that directly target the RemoteMouse app and server. These vulnerabilities typically affected the Emote Remote Mouse through 3.015.

The app basically transmits the information about running processes and recently used apps in plaintext. Thus, an attacker merely needs to send a maliciously crafted packet to minimize or maximize the window of a running process (CVE-2021-27569), close it (CVE-2021-27570), or retrieve data about running or recently used apps along with their file paths and icons (CVE-2021-27571).

Whereas, two other vulnerabilities CVE-2021-27572 and CVE-2021-27573 allow an unauthenticated remote attacker to achieve arbitrary code execution via maliciously crafted UDP packets.

Besides, another bug, CVE-2021-27574 existed because the app used HTTP to check and request updates. This allows an adversary to perform a machine-in-the-middle attack thereby targeting the users with a malicious update.

The following video quickly demonstrates Mouse Trap. Whereas, the researcher has also shared other technical details on GitHub.

No Patch Yet

The researcher discovered the vulnerabilities in February 2021, after which, he reached out to RemoteMouse. However, even after the end of a 90-day disclosure timeline, the researcher got no response from the team.

Persinger also reached out to Google, Microsoft, and Apple to inform them of the bugs. But he got no response. While the app also continues to exist as is.

After his report, the app developers have also released some updates, yet they lacked the patches to the Mouse Trap bugs. Therefore, users of RemoteMouse should be aware of the underlying security risks associated with the continued use of the app.

Analytics

The _ga is asssociated with Google Universal Analytics - which is a significant update to Google's more commonly used analytics service. This cookie is used to distinguish unique users by assigning a randomly generated number as a client identifier. It is included in each page request in a site and used to calculate visitor, session and campaign data for the sites analytics reports. By default it is set to expire after 2 years, although this is customisable by website owners.

The _gat global object is used to create and retrieve tracker objects, from which all other methods are invoked. Therefore the methods in this list should be run only off a tracker object created using the _gat global variable. All other methods should be called using the _gaq global object for asynchronous tracking.

_gid works as a user navigates between web pages, they can use the gtag.js tagging library to record information about the page the user has seen (for example, the page's URL) in Google Analytics. The gtag.js tagging library uses HTTP Cookies to "remember" the user's previous interactions with the web pages.
