CVE-2018-14999: The Leagoo P1 device with a build fingerprint of sp7731c_1h10_32v4_bird:6.0/MRA58K/android.20170629.214736:us…

CVE-2018-14999 is rated critical with a CVSS v3.0 base score of 9.1 and NVD lists Leagoo P1 Firmware as the affected product. Per its scoring, it can be exploited over the network, without authentication, without any user interaction.

Vulnerability description

The Leagoo P1 device with a build fingerprint of sp7731c_1h10_32v4_bird:6.0/MRA58K/android.20170629.214736:user/release-keys contains a pre-installed platform app with a package name of com.wtk.factory (versionCode=1, versionName=1.0) that contains an exported broadcast receiver named com.wtk.factory.MMITestReceiver allows any app co-located on the device to programmatically initiate a factory reset. In addition, the app initiating the factory reset does not require any permissions. A factory reset will remove all user data and apps from the device. This will result in the loss of any data that have not been backed up or synced externally. The capability to perform a factory reset is not directly available to third-party apps (those that the user installs themselves with the exception of enabled Mobile Device Management (MDM) apps), although this capability can be obtained by leveraging an unprotected app component of a pre-installed platform app.
