Detailsinfo

A vulnerability, which was classified as critical, was found in Essential Phone (version unknown). This affects an unknown function of the component Factory Reset Handler. The manipulation with an unknown input leads to a input validation vulnerability. CWE is classifying the issue as CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

The Essential Phone Android device with a build fingerprint of essential/mata/mata:8.1.0/OPM1.180104.166/297:user/release-keys contains a pre-installed platform app with a package name of com.ts.android.hiddenmenu (versionName=1.0, platformBuildVersionName=8.1.0) that contains an exported activity app component named com.ts.android.hiddenmenu.rtn.RTNResetActivity that 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.
