The Oppo F5 Android device with a build fingerprint of OPPO/CPH1723/CPH1723:7.1.1/N6F26Q/1513597833:user/release-keys contains a pre-installed platform app with a package name of com.dropboxchmod (versionCode=1, versionName=1.0) that contains an exported service named com.dropboxchmod.DropboxChmodService that allows any app co-located on the device to supply arbitrary commands to be executed as the system user. This 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), and obtains the user's text messages, and more. This vulnerability can also be used to secretly record audio of the user without their awareness on the Oppo F5 device. The pre-installed com.oppo.engineermode app (versionCode=25, versionName=V1.01) has an exported activity that can be started to initiate a recording and quickly dismissed. The activity can be started in a way that the user will not be able to see the app in the recent apps list. The resulting audio amr file can be copied from a location on internal storage using the arbitrary command execution as system user vulnerability. Executing commands as system user can allow a third-party app to 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.

In ColorOS (oppo mobile phone operating system, based on AOSP frameworks/native code position/services/surfaceflinger surfaceflinger.CPP), RGB is defined on the stack but uninitialized, so when the screenShot function to RGB value assignment, will not initialize the value is returned to the attackers, leading to values on the stack information leakage, the vulnerability can be used to bypass attackers ALSR.

Dynamic loading of services in the backup and restore SDK leads to elevated privileges, affected product is com.coloros.codebook V2.0.0_5493e40_200722.

QualityProtect has a vulnerability to execute arbitrary system commands, affected product is com.oppo.qualityprotect V2.0.

OvoiceManager has system permission to write vulnerability reports for arbitrary files, affected product is com.oppo.ovoicemanager V2.0.1.

In functions charging_limit_current_write and charging_limit_time_write in /SM8250_Q_Master/android/vendor/oppo_charger/oppo/oppo_charger.c have not checked the parameters, which causes a vulnerability.

In /SM8250_Q_Master/android/vendor/oppo_charger/oppo/charger_ic/oppo_mp2650.c, the function mp2650_data_log_write in mp2650_data_log_write does not check the parameter len which causes a vulnerability.

In /SM8250_Q_Master/android/vendor/oppo_charger/oppo/oppo_vooc.c, the function proc_fastchg_fw_update_write in proc_fastchg_fw_update_write does not check the parameter len, resulting in a vulnerability.

In /SM8250_Q_Master/android/vendor/oppo_charger/oppo/charger_ic/oppo_da9313.c, failure to check the parameter buf in the function proc_work_mode_write in proc_work_mode_write causes a vulnerability.

ColorOS pregrant dangerous permissions to apps which are listed in a whitelist xml named default-grant-permissions.But some apps in whitelist is not installed, attacker can disguise app with the same package name to obtain dangerous permission.

In ACE2 ColorOS11, the attacker can obtain the foreground package name through permission promotion, resulting in user information disclosure.
