Detailsinfo

A vulnerability, which was classified as critical, was found in T-Mobile Device (version unknown). This affects an unknown function. The manipulation with an unknown input leads to a command injection vulnerability. CWE is classifying the issue as CWE-77. The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

An issue was discovered in a third-party com.factory.mmigroup component, shipped on devices from multiple device manufacturers. Certain software builds for various Android devices contain a vulnerable pre-installed app with a package name of com.factory.mmigroup (versionCode='3', versionName='2.1) that allows local third-party apps to perform various actions, due to inadequate access control, in its context (system user), but the functionalities exposed depend on the specific device. The following capabilities are exposed to zero-permission, third-party apps on the following devices: arbitrary AT command execution via AT command injection (T-Mobile Revvl 6 Pro 5G, T-Mobile Revvl V+ 5G, and Boost Mobile Celero 5G); programmatic factory reset (Samsung Galaxy A03S, T-Mobile Revvl 6 Pro 5G, T-Mobile Revvl V+ 5G, Boost Mobile Celero, Realme C25Y, and Lenovo Tab M8 HD), leaking IMEI (Samsung Galaxy A03S, T-Mobile Revvl 6 Pro 5G, T-Mobile Revvl V+ 5G, Boost Mobile Celero, and Realme C25Y); leaking serial number (Samsung Galaxy A03s, T-Mobile Revvl 6 Pro 5G, T-Mobile Revvl V+ 5G, Boost Mobile Celero, Realme C25Y, and Lenovo Tab M8 HD); powering off the device (Realme C25Y, Samsung Galaxy A03S, and T-Mobile Revvl 6 Pro 5G); and programmatically enabling/disabling airplane mode (Samsung Galaxy A03S, T-Mobile Revvl 6 Pro 5G, T-Mobile Revvl V+ 5G, Boost Mobile Celero, and Realme C25Y); and enabling Wi-Fi, Bluetooth, and GPS (Samsung Galaxy A03S, T-Mobile Revvl 6 Pro 5G, T-Mobile Revvl V+ 5G, Boost Mobile Celero, and Realme C25Y). No permissions or special privileges are necessary to exploit the vulnerabilities in the com.factory.mmigroup app. No user interaction is required beyond installing and running a third-party app. The software build fingerprints for each confirmed vulnerable device are as follows: Boost Mobile Celero 5G (Celero5G/Jupiter/Jupiter:11/RP1A.200720.011/SW_S98119AA1_V067:user/release-keys, Celero5G/Jupiter/Jupiter:11/RP1A.200720.011/SW_S98119AA1_V064:user/release-keys, Celero5G/Jupiter/Jupiter:11/RP1A.200720.011/SW_S98119AA1_V061:user/release-keys, and Celero5G/Jupiter/Jupiter:11/RP1A.200720.011/SW_S98119AA1_V052:user/release-keys); Samsung Galaxy A03S (samsung/a03sutfn/a03su:13/TP1A.220624.014/S134DLUDU6CWB6:user/release-keys and samsung/a03sutfn/a03su:12/SP1A.210812.016/S134DLUDS5BWA1:user/release-keys); Lenovo Tab M8 HD (Lenovo/LenovoTB-8505F/8505F:10/QP1A.190711.020/S300637_220706_BMP:user/release-keys and Lenovo/LenovoTB-8505F/8505F:10/QP1A.190711.020/S300448_220114_BMP:user/release-keys); T-Mobile Revvl 6 Pro 5G (T-Mobile/Augusta/Augusta:12/SP1A.210812.016/SW_S98121AA1_V070:user/release-keys and T-Mobile/Augusta/Augusta:12/SP1A.210812.016/SW_S98121AA1_V066:user/release-keys); T-Mobile Revvl V+ 5G (T-Mobile/Sprout/Sprout:11/RP1A.200720.011/SW_S98115AA1_V077:user/release-keys and T-Mobile/Sprout/Sprout:11/RP1A.200720.011/SW_S98115AA1_V060:user/release-keys); and Realme C25Y (realme/RMX3269/RED8F6:11/RP1A.201005.001/1675861640000:user/release-keys, realme/RMX3269/RED8F6:11/RP1A.201005.001/1664031768000:user/release-keys, realme/RMX3269/RED8F6:11/RP1A.201005.001/1652814687000:user/release-keys, and realme/RMX3269/RED8F6:11/RP1A.201005.001/1635785712000:user/release-keys). This malicious app sends a broadcast Intent to com.factory.mmigroup/.MMIGroupReceiver. This causes the com.factory.mmigroup app to dynamically register for various action strings. The malicious app can then send these strings, allowing it to perform various behaviors that the com.factory.mmigroup app exposes. The actual behaviors exposed by the com.factory.mmigroup app depend on device model and chipset. The com.factory.mmigroup app executes as the "system" user, allowing it to interact with the baseband processor and perform various other sensitive actions.
