DescriptionGitHub Advisory

ADB Explorer is a fluent UI for ADB on Windows. Versions 0.9.26020 and below fail to validate the integrity or authenticity of the ADB binary path specified in the ManualAdbPath setting before executing it, allowing arbitrary code execution with the privileges of the current user. An attacker can exploit this by crafting a malicious App.txt settings file that points ManualAdbPath to an arbitrary executable, then convincing a victim to launch the application with a command-line argument directing it to the malicious configuration directory. This vulnerability could be leveraged through social engineering tactics, such as distributing a shortcut bundled with a crafted settings file in an archive, resulting in RCE upon application startup. Thus issue has been fixed in version 0.9.26021.

AnalysisAI

Arbitrary code execution in ADB Explorer version 0.9.26020 and earlier on Windows allows local attackers to execute malicious binaries by manipulating the ManualAdbPath configuration setting without integrity validation. An attacker can exploit this through social engineering by distributing a crafted settings file that redirects the application to a malicious executable, gaining code execution with user privileges. The vulnerability requires user interaction to launch the application with a malicious configuration directory.
