ADB MCP Server Command Injection Vulnerability

CVE advisorySeverity: CRITICAL (CVSS 9.8)

CVE-2025-59834

The affected component is a Model Context Protocol (MCP) server used for local development integration between AI agents and ADB (Android Debug Bridge). This tool is intended for local execution by developers to interact with locally connected Android devices and is not a service designed or typically deployed to be exposed to the public internet.

Horizon Alert

Summary of the vulnerability and why it matters

A critical vulnerability has been identified in the ADB MCP Server, a tool used for connecting Android devices to ADB. This flaw could allow unauthorized command execution by remote attackers, impacting the integrity and availability of connected systems. The main concern is confirming the relevance and exposure of this tool within our environment.

Confirm if this tool is in use.

Attack Path

How an attacker could exploit the issue

An attacker could target the ADB MCP Server by sending specially crafted requests to its network interface. Because the server processes these requests without properly sanitizing certain inputs, an attacker can inject malicious commands. If successful, this vulnerability could allow an attacker to execute arbitrary commands on the server, potentially leading to significant compromise.

No authentication required for attack.
Triggered by sending malicious network requests.
Risk of arbitrary command execution.

Live Threat

Current exploitation, exposure, and threat context

ADB MCP Server, when exposed externally and not properly secured, could allow an attacker to inject and execute arbitrary commands on the server. This could potentially affect the integrity and availability of the server and any connected Android devices.

Operational Fix

Recommended remediation, mitigation, and detection steps

The ADB MCP Server, used for Android device interaction via ADB, has a command injection vulnerability. This tool is typically used by developers for local integration and is not designed for public internet exposure. The first action is to identify any instances of this server, confirm its usage context and criticality, and then engage the responsible development or platform team for remediation planning.

Application owners should manage remediation.
Verify local development environments.
Coordinate with development teams.

Frequently asked questions

What is the srmorete adb_mcp_server?

The adb_mcp_server is a specialized software component that acts as a bridge using the Model Context Protocol (MCP). It allows AI agents and development tools to interact directly with Android devices through the Android Debug Bridge (ADB). Developers primarily use it to facilitate automation and debugging workflows by integrating physical or emulated Android hardware into their local development environments.

What does the command injection vulnerability in CVE-2025-59834 mean?

This vulnerability, classified as CWE-77 and CWE-78, occurs when the server fails to properly sanitize input before passing it to system commands. Instead of just processing legitimate requests, the software interprets malicious input as executable code. This allows an attacker to manipulate the server's underlying operating system to run unauthorized commands with the server's own permissions.

How can an attacker trigger this vulnerability?

The flaw is triggered when the server receives a specially crafted network request containing malicious input that it processes as a command. It is important to note that this requires the server to be listening for network traffic; the bug is not triggered by standard, non-malicious interactions with the device or by local ADB commands that do not flow through the vulnerable MCP tool definition logic.

Is my instance of adb_mcp_server at risk?

According to Halo Surface Signal, this tool is designed for local development and is typically not meant to be reachable from the public internet. The primary risk exists if the server is incorrectly configured to accept connections from untrusted networks. If your instance is strictly isolated within a secure, local development workstation, the potential for a remote attacker to reach it is significantly lower.

How do I secure my systems against this CVE?

Your first step is to conduct an inventory to locate any systems running versions of the adb_mcp_server up to 0.1.0. Once identified, coordinate with your development team to confirm if the tool is necessary for current projects. If it is in use, the definitive solution is to update the software to the patched version found in the project's repository, as the vulnerability is resolved in newer code releases.
