📋 TL;DR
CVE-2025-59834 is a command injection vulnerability in ADB MCP Server versions 0.1.0 and earlier that allows attackers to execute arbitrary commands on the host system. The vulnerability exists in the server's tool definitions and implementations, enabling remote code execution. Anyone using the vulnerable ADB MCP Server to interact with Android devices is affected.
💻 Affected Systems
- ADB MCP Server
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise with attacker gaining root/administrator privileges, data exfiltration, and persistent backdoor installation.
Likely Case
Unauthorized command execution leading to data theft, privilege escalation, and lateral movement within the network.
If Mitigated
Limited impact with proper network segmentation and least privilege access controls in place.
🎯 Exploit Status
The vulnerability is in the MCP tool implementations, making exploitation straightforward for attackers familiar with the protocol.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Patched via commit 041729c0b25432df3199ff71b3163a307cf4c28c
Vendor Advisory: https://github.com/srmorete/adb-mcp/security/advisories/GHSA-54j7-grvr-9xwg
Restart Required: Yes
Instructions:
1. Update to the latest version from GitHub. 2. Replace vulnerable source files with patched versions. 3. Restart the ADB MCP Server service.
🔧 Temporary Workarounds
Network Isolation
linuxRestrict network access to the ADB MCP Server to trusted IPs only
iptables -A INPUT -p tcp --dport [MCP_PORT] -s [TRUSTED_IP] -j ACCEPT
iptables -A INPUT -p tcp --dport [MCP_PORT] -j DROP
Service Account Restriction
linuxRun the ADB MCP Server with minimal privileges using a dedicated service account
sudo useradd -r -s /bin/false adbmcp
sudo chown -R adbmcp:adbmcp /path/to/adb-mcp
🧯 If You Can't Patch
- Disable or remove the ADB MCP Server entirely
- Implement strict network segmentation and firewall rules to isolate the server
🔍 How to Verify
Check if Vulnerable:
Check if running ADB MCP Server version 0.1.0 or earlier by examining package version or source code for vulnerable patterns in tool implementationsCheck Version:
Check package.json for version or examine git log for commit historyVerify Fix Applied:
Verify commit 041729c0b25432df3199ff71b3163a307cf4c28c is present in the codebase and the server has been restarted📡 Detection & Monitoring
