The scenario describes an on-device, app-based rooting approach that does not rely on a PC connection, USB debugging, or a bootloader unlock workflow. In CEH mobile platform coverage, this aligns with “one-click” rooting tools that package exploits to elevate privileges directly from user space to root on the device. These tools typically target known vulnerabilities in the Android OS, vendor kernels, or system services to obtain root privileges and then install a management component to maintain elevated access.

KingoRoot is commonly cited in ethical hacking training contexts as a popular one-click rooting solution that can run as an Android application and attempt to root a device without a computer, depending on the device model, Android version, and patch level. This directly matches the prompt: Sofia installs a mobile application, it “exploits a system vulnerability,” and it achieves root “without requiring a PC.” The constraints given, USB debugging disabled and OEM unlock restrictions, make PC-assisted ADB workflows or bootloader-based rooting less feasible, which further supports an exploit-driven, on-device rooting tool.

Magisk Manager is primarily a root management and systemless modification framework and typically assumes the device is already rooted or that the user can patch the boot image and flash it, often requiring bootloader unlock steps that OEM restrictions would block. “One Click Root” is a generic label rather than a specific tool in many CEH-style question banks. RootMaster is another one-click tool, but KingoRoot is the most widely recognized and frequently referenced for direct APK-based rooting in this context.
