The Leagoo P1 Android device with a build fingerprint of sp7731c_1h10_32v4_bird:6.0/MRA58K/android.20170629.214736:user/release-keys contains a hidden root privilege escalation capability to achieve command execution as the root user. They have made modifications that allow a user with physical access to the device to obtain a root shell via ADB by modifying read-only system properties at runtime. Specifically, modifying the ro.debuggable and the ro.secure system properties to a certain value and then restarting the ADB daemon allows for a root shell to be obtained via ADB. El dispositivo Android "Leagoo P1" con una huella de build de sp7731c_1h10_32v4_bird:6.0/MRA58K/android.20170629.214736:user/release-keys contiene una capacidad de escalado de privilegios root escondida para lograr la ejecución de comandos como el usuario root. Se han realizado modificaciones que permiten a usuarios con acceso físico al dispositivo obtener un shell root mediante ADB, modificando las propiedades de sistema, del tipo solo lectura, en tiempo de ejecución. • https://www.kryptowire.com/portal/android-firmware-defcon-2018 https://www.kryptowire.com/portal/wp-content/uploads/2018/12/DEFCON-26-Johnson-and-Stavrou-Vulnerable-Out-of-the-Box-An-Eval-of-Android-Carrier-Devices-WP-Updated.pdf • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •

The Leagoo Z5C Android 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.android.settings (versionCode=23, versionName=6.0-android.20170630.092853) that contains an exported broadcast receiver 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. • https://www.kryptowire.com/portal/android-firmware-defcon-2018 https://www.kryptowire.com/portal/wp-content/uploads/2018/12/DEFCON-26-Johnson-and-Stavrou-Vulnerable-Out-of-the-Box-An-Eval-of-Android-Carrier-Devices-WP-Updated.pdf • CWE-862: Missing Authorization •
CVSS: 9.3EPSS: 1%CPEs: 38EXPL: 1CVE-2016-6564 – Ragentek Android software contains an over-the-air update mechanism that communicates over an unencrypted channel, which can allow a remote attacker to execute arbitrary code with root privileges
https://notcve.org/view.php?id=CVE-2016-6564
Android devices with code from Ragentek contain a privileged binary that performs over-the-air (OTA) update checks. Additionally, there are multiple techniques used to hide the execution of this binary. This behavior could be described as a rootkit. This binary, which resides as /system/bin/debugs, runs with root privileges and does not communicate over an encrypted channel. The binary has been shown to communicate with three hosts via HTTP: oyag[.]lhzbdvm[.]com oyag[.]prugskh[.]net oyag[.]prugskh[.]com Server responses to requests sent by the debugs binary include functionalities to execute arbitrary commands as root, install applications, or update configurations. • https://www.bitsighttech.com/blog/ragentek-android-ota-update-mechanism-vulnerable-to-mitm-attack https://www.kb.cert.org/vuls/id/624539 https://www.securityfocus.com/bid/94393 • CWE-264: Permissions, Privileges, and Access Controls CWE-494: Download of Code Without Integrity Check •
