Detailsinfo

A vulnerability was found in TCL 20XE (the affected version is unknown). It has been declared as critical. Affected by this vulnerability is an unknown code. The manipulation with an unknown input leads to a access control vulnerability. The CWE definition for the vulnerability is CWE-284. The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

Certain software builds for the TCL 20XE Android device contain a vulnerable, pre-installed app with a package name of com.tct.gcs.hiddenmenuproxy (versionCode='2', versionName='v11.0.1.0.0201.0') that allows local third-party apps to programmatically perform a factory reset due to inadequate access control. No permissions or special privileges are necessary to exploit the vulnerability in the com.tct.gcs.hiddenmenuproxy app. No user interaction is required beyond installing and running a third-party app. The software build fingerprints for each confirmed vulnerable build are as follows: TCL/5087Z_BO/Doha_TMO:11/RP1A.200720.011/PB7I-0:user/release-keys and TCL/5087Z_BO/Doha_TMO:11/RP1A.200720.011/PB83-0:user/release-keys. This malicious app sends a broadcast intent to the exported com.tct.gcs.hiddenmenuproxy/.rtn.FactoryResetReceiver receiver component, which initiates a programmatic factory reset.
