Microsoft UFO ADB Command Injection via Mobile MCP Server

Publication date: 2026-10-06

Last updated on: 2026-10-06

Assigner: GitHub, Inc.

Description
Microsoft UFO is an open-source framework for intelligent automation across devices and platforms. Prior to 3.0.10, the type_text and launch_app tools in ufo/client/mcp/http_servers/mobile_mcp_server.py pass the authenticated caller-controlled text and package_name parameters into adb shell command argument positions without comprehensive validation. The adb client joins those arguments into a remote command string that the Android shell reparses, allowing shell metacharacters to execute additional commands on an authorized connected device as the Android shell user. Exploitation requires a valid Mobile MCP API key and a reachable device authorized for ADB, and it does not establish host operating-system execution, Android root execution, or access beyond the Android shell-user privileges. This issue is fixed in version 3.0.10.

Executive Summary

This vulnerability exists in Microsoft UFO versions prior to 3.0.10. It involves the type_text and launch_app tools in the mobile MCP server passing user-controlled parameters directly into adb shell commands without proper validation. This allows attackers with a valid Mobile MCP API key and authorized ADB device to inject shell metacharacters, executing additional commands on the connected Android device as the shell user.

Detection Guidance

Detection requires checking for Microsoft UFO versions prior to 3.0.10. Run 'pip show microsoft-ufo' to check the installed version. If the version is below 3.0.10, the system is vulnerable. Inspect logs for unusual ADB shell commands or unexpected device interactions.

Impact Analysis

If exploited, this vulnerability could allow an attacker to run unauthorized commands on your authorized Android device through the adb shell. This could lead to data theft, device manipulation, or further compromise of connected systems, but only within the limited privileges of the Android shell user account.

Compliance Impact

This vulnerability could potentially violate compliance requirements that mandate secure handling of data and systems, such as unauthorized command execution on devices. Organizations using Microsoft UFO may need to update to version 3.0.10 or later to maintain compliance with standards requiring protection against command injection attacks.

Mitigation Strategies

Upgrade Microsoft UFO to version 3.0.10 or later immediately. Restrict Mobile MCP API key access to trusted users and devices. Disable ADB access for unauthorized devices. Monitor network traffic for suspicious ADB-related commands.
