Weakness: CWE-40

Description

ADB Explorer is a fluent UI for ADB on Windows. In versions prior to Beta 0.9.26022, ADB-Explorer allows the `ManualAdbPath` settings variable, which determines the path of the ADB binary to be executed, to be set to a Universal Naming Convention (UNC) path in the application's settings file. This allows an attacker to set the binary's path to point to a remote network resource, hosted on an attacker-controlled network share, thus granting the attacker full control over the binary being executed by the app. An attacker may leverage this vulnerability to execute code remotely on a victim's machine with the privileges of the user running the app. Exploitation is made possible by convincing a victim to run a shortcut of the app that points to a custom `App.txt` settings file, which sets `ManualAdbPath` (for example, when downloaded in an archive file). Version Beta 0.9.26022 fixes the issue.
