6 Unpatched Flaws Disclosed in Distant Mouse App for Android and iOS

As many as six zero-days have been uncovered in an utility referred to as Distant Mouse, permitting a distant attacker to attain full code execution with none person interplay.

The unpatched flaws, collectively named ‘Mouse Trap,‘ had been disclosed on Wednesday by safety researcher Axel Persinger, who mentioned, “It is clear that this utility may be very susceptible and places customers in danger with unhealthy authentication mechanisms, lack of encryption, and poor default configuration.”

Distant Mouse is a distant management utility for Android and iOS that turns cell phones and tablets right into a wi-fi mouse, keyboard, and trackpad for computer systems, with help for voice typing, adjusting laptop quantity, and switching between purposes with the assistance of a Distant Mouse server put in on the machine. The Android app alone has been put in over 10 million instances.

In a nutshell, the problems, which had been recognized by analysing the packets despatched from the Android app to its Home windows service, may enable an adversary to intercept a person’s hashed password, rendering them prone to rainbow table assaults and even replay the instructions despatched to the pc.

A fast abstract of the six flaws is as follows –

  • CVE-2021-27569: Maximize or decrease the window of a operating course of by sending the method identify in a crafted packet.
  • CVE-2021-27570: Shut any operating course of by sending the method identify in a specifically crafted packet.
  • CVE-2021-27571: Retrieve lately used and operating purposes, their icons, and their file paths.
  • CVE-2021-27572: An authentication bypass through packet replay, permitting distant unauthenticated customers to execute arbitrary code through crafted UDP packets even when passwords are set.
  • CVE-2021-27573: Execute arbitrary code through crafted UDP packets with no prior authorization or authentication.
  • CVE-2021-27574: Perform a software program supply-chain assault by making the most of the app’s use of cleartext HTTP to examine and request updates, leading to a state of affairs the place a sufferer may doubtlessly obtain a malicious binary rather than the actual replace.

Persinger mentioned he reported the failings to Distant Mouse on Feb. 6, 2021, however famous he “by no means obtained a response from the seller,” forcing him to publicly reveal the bugs following the 90-day disclosure deadline. We have now reached out to the builders of Distant Mouse, and we are going to replace the story if we hear again.
