Path Traversal Microsoft Windows

Description

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.

Analysis

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. …

Remediation

Within 24 hours: Inventory all systems running ADB Explorer 0.9.26020 or earlier; disable or uninstall the application on non-critical systems pending remediation. Within 7 days: Establish a mandatory upgrade timeline to versions beyond 0.9.26020 once available; implement access controls restricting ADB Explorer usage to authorized personnel only. …
