No exploitation reported by the sources we read.

  • Published2019-03-22

Am I affected?

With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.

Description

The SHAREit application before 4.0.36 for Android allows a remote attacker (on the same network or joining public "open" Wi-Fi hotspots created by the application when file transfer is initiated) to bypass authentication by trying to fetch a non-existing page. When the non-existing page is requested, the application responds with a 200 status code and empty page, and adds the requesting client device into the list of recognized devices.
