2DescriptionGitHub Advisory
ADB Explorer is a fluent UI for ADB on Windows. Versions 0.9.26020 and below have an unvalidated command-line argument that allows any user to trigger recursive deletion of arbitrary directories on the Windows filesystem. ADB Explorer accepts an optional path argument to set a custom data directory, but only check whether the path exists. The ClearDrag() method calls Directory.Delete(dir, true) on every subdirectory of that path at both application startup and exit. An attacker can craft a malicious shortcut (.lnk) or batch script that launches ADB Explorer with a critical directory (e.g. C:\Users\%USERNAME%\Documents) as the argument, causing permanent recursive deletion of all its subdirectories. Any user who launches ADB Explorer via a crafted shortcut, batch file, or script loses the contents of the targeted directory permanently (deletion bypasses the Recycle Bin). This issue has been fixed in version 0.9.26021.
AnalysisAI
ADB Explorer through version 0.9.26020 fails to validate user-supplied directory paths, enabling local attackers to trigger recursive deletion of arbitrary filesystem directories including critical system and user folders. An attacker can exploit this by crafting a malicious shortcut or script that launches the application with a sensitive path argument, causing permanent data loss when the application processes the ClearDrag() function at startup or exit. Any user tricked into launching ADB Explorer via a weaponized shortcut or batch file faces complete loss of targeted directories such as Documents or user profile folders.
