CVE-2018-15007

The Sky Elite 6.0L+ Android device with a build fingerprint of SKY/x6069_trx_l601_sky/x6069_trx_l601_sky:6.0/MRA58K/1482897127:user/release-keys contains a pre-installed platform app with a package name of com.fw.upgrade.sysoper (versionCode=238, versionName=2.3.8) that contains an exported broadcast receiver app component named com.adups.fota.sysoper.WriteCommandReceiver that allows any app co-located on the device to supply arbitrary commands to be executed as the system user. The com.fw.upgrade.sysoper app cannot be disabled by the user and the attack can be performed by a zero-permission app. Executing commands as system user can allow a third-party app to video record the user’s screen, factory reset the device, obtain the user’s notifications, read the logcat logs, inject events in the Graphical User Interface (GUI), change the default Input Method Editor (IME) (e.g., keyboard) with one contained within the attacking app that contains keylogging functionality, obtain the user’s text messages, and more.

CVE-2018-14985

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.

CVE-2018-15004

The Coolpad Canvas device with a build fingerprint of Coolpad/cp3636a/cp3636a:7.0/NRD90M/093031423:user/release-keys contains a platform app with a package name of com.qualcomm.qti.modemtestmode (versionCode=24, versionName=7.0) that contains an exported service app component named com.qualcomm.qti.modemtestmode.MbnTestService that allows any app on the device to set certain system properties as the com.android.phone user. When an app sets the persist.service.logr.enable system property to a value of 1, an app with a package name of com.yulong.logredirect (versionCode=20160622, versionName=5.25_20160622_01) will start writing the system-wide logcat log, kernel log, and a tcpdump network traffic capture to external storage. Furthermore, on the Coolpad Canvas device, the com.android.phone app writes the destination phone number and body of the text message for outgoing text messages. A notification when logging can be avoided if the log is enabled after device startup and disabled prior to device shutdown by setting the system properties using the exported interface of the com.qualcomm.qti.modemtestmode app. Any app with the READ_EXTERNAL_STORAGE permission can access the log files.

CVE-2018-15002

The Vivo V7 device with a build fingerprint of vivo/1718/1718:7.1.2/N2G47H/compil11021857:user/release-keys allows any app co-located on the device to set system properties as the com.android.phone user. The com.qualcomm.qti.modemtestmode app (versionCode=25, versionName=7.1.2) that contains an exported service named com.qualcomm.qti.modemtestmode.MbnTestService that allows any app co-located on the device to provide key-value pairs to set certain system properties. Notably, system properties with the persist.* prefix can be set which will survive a reboot. On the Vivo V7 device, when the persist.sys.input.log property is set to have a value of yes, the user’s screen touches be written to the logcat log by the InputDispatcher for all apps. The system-wide logcat log can be obtained from external storage via a different known vulnerability on the device. The READ_EXTERNAL_STORAGE permission is necessary to access the log files containing the user’s touch coordinates. With some effort, the user’s touch coordinates can be mapped to key presses on a keyboard.

CVE-2018-15001

The Vivo V7 Android device with a build fingerprint of vivo/1718/1718:7.1.2/N2G47H/compil11021857:user/release-keys contains a platform app with a package name of com.vivo.bsptest (versionCode=1, versionName=1.0) containing an exported activity app component named com.vivo.bsptest.BSPTestActivity that allows any app co-located on the device to initiate the writing of the logcat log, bluetooth log, and kernel log to external storage. When logging is enabled, there is a notification in the status bar, so it is not completely transparent to the user. The user can cancel the logging, but it can be re-enabled since the app with a package name of com.vivo.bsptest cannot be disabled. The writing of these logs can be initiated by an app co-located on the device, although the READ_EXTERNAL_STORAGE permission is necessary to for an app to access the log files.

CVE-2018-14979

The ASUS ZenFone 3 Max Android device with a build fingerprint of asus/US_Phone/ASUS_X008_1:7.0/NRD90M/US_Phone-14.14.1711.92-20171208:user/release-keys contains a pre-installed app with a package name of com.asus.loguploader (versionCode=1570000275, versionName=7.0.0.55_170515). This app contains an exported service app component named com.asus.loguploader.LogUploaderService that, when accessed with a particular action string, will write a bugreport (kernel log, logcat log, and the state of system services including the text of active notifications), Wi-Fi Passwords, and other system data to external storage (sdcard). Any app with the READ_EXTERNAL_STORAGE permission on this device can read this data from the sdcard after it has been dumped there by the com.asus.loguploader. Third-party apps are not allowed to directly create a bugreport or access the user’s stored wireless network credentials.
