CVE-2025-61492
📋 TL;DR
A command injection vulnerability in terminal-controller-mcp 0.1.7 allows attackers to execute arbitrary system commands by providing malicious input to the execute_command function. This affects any system running the vulnerable version of this terminal controller package, potentially giving attackers full control of the affected system.
💻 Affected Systems
- terminal-controller-mcp
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing attackers to execute arbitrary commands with the privileges of the running process, potentially leading to data theft, ransomware deployment, or lateral movement within the network.
Likely Case
Remote code execution leading to unauthorized access, data exfiltration, or installation of backdoors on affected systems.
If Mitigated
Limited impact if proper input validation and command sanitization are implemented, restricting attackers to specific allowed commands only.
🎯 Exploit Status
Command injection vulnerabilities are typically easy to exploit once the attack vector is identified. The GitHub issues suggest the vulnerability is known and may have exploit code available.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None available
Restart Required: No
Instructions:
1. Check the GitHub repository for updates
2. If a patched version is available, update terminal-controller-mcp
3. Review and test the update before deploying to production
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement strict input validation and command sanitization before passing user input to execute_command
Implement input validation in your application code before calling execute_command
Restrict Command Execution
allLimit the commands that can be executed through the vulnerable function
Implement allow-listing of permitted commands in your application
🧯 If You Can't Patch
- Isolate affected systems from critical networks and internet access
- Implement strict network segmentation and firewall rules to limit access to the vulnerable service
🔍 How to Verify
Check if Vulnerable:
Check if terminal-controller-mcp version 0.1.7 is installed in your environment
Check Version:
npm list terminal-controller-mcp
Verify Fix Applied:
Verify that terminal-controller-mcp has been updated to a version later than 0.1.7 or removed
📡 Detection & Monitoring
Log Indicators:
- Unusual command execution patterns
- Commands with shell metacharacters (;, &, |, $)
- Commands from unexpected sources
Network Indicators:
- Unexpected outbound connections from systems running terminal-controller-mcp
- Suspicious payloads in API requests to the vulnerable endpoint
SIEM Query:
source="application_logs" AND (process="terminal-controller-mcp" OR message="execute_command") AND (command CONTAINS ";" OR command CONTAINS "&" OR command CONTAINS "|")
