CVE-2020-7606
📋 TL;DR
CVE-2020-7606 is a command injection vulnerability in docker-compose-remote-api that allows remote attackers to execute arbitrary commands on the host system. The vulnerability exists because user-controlled input is passed directly to exec() without sanitization. This affects any system using vulnerable versions of this npm package.
💻 Affected Systems
- docker-compose-remote-api
📦 What is this software?
Docker Compose Remote Api by Docker Compose Remote Api Project
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise with attacker gaining root-level access to the host, allowing data theft, ransomware deployment, or lateral movement within the network.
Likely Case
Remote code execution leading to container escape, privilege escalation, and unauthorized access to sensitive data or resources.
If Mitigated
Limited impact if proper network segmentation, least privilege, and input validation are implemented, potentially containing the attack to isolated environments.
🎯 Exploit Status
Exploitation is straightforward as it involves simple command injection with minimal prerequisites.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: None - package appears abandoned
Vendor Advisory: https://snyk.io/vuln/SNYK-JS-DOCKERCOMPOSEREMOTEAPI-560125
Restart Required: Yes
Instructions:
1. Remove docker-compose-remote-api package entirely. 2. Replace with alternative solutions. 3. Restart affected services.
🔧 Temporary Workarounds
Input validation and sanitization
allImplement strict input validation for serviceName parameter to prevent command injection
// JavaScript example: validate serviceName against allowed patterns
const allowedPattern = /^[a-zA-Z0-9_-]+$/;
if (!allowedPattern.test(serviceName)) { throw new Error('Invalid service name'); }
Network access restrictions
linuxRestrict network access to the docker-compose-remote-api service
# Linux firewall example
sudo iptables -A INPUT -p tcp --dport [API_PORT] -s [TRUSTED_NETWORK] -j ACCEPT
sudo iptables -A INPUT -p tcp --dport [API_PORT] -j DROP
🧯 If You Can't Patch
- Implement strict network segmentation to isolate affected systems
- Deploy runtime application self-protection (RASP) or WAF with command injection rules
🔍 How to Verify
Check if Vulnerable:
Check package.json for docker-compose-remote-api version ≤0.1.4 or examine code for vulnerable exec() function usageCheck Version:
npm list docker-compose-remote-apiVerify Fix Applied:
Confirm docker-compose-remote-api is removed from package.json and node_modules, or verify input validation is implemented📡 Detection & Monitoring
Log Indicators:
- Unusual exec() calls with suspicious serviceName parameters
- Unexpected process spawns from Node.js application
- Commands containing shell metacharacters in serviceName
Network Indicators:
- Unusual outbound connections from the Node.js process
- Traffic to unexpected ports or external IPs
SIEM Query:
source="application.log" AND "exec(" AND serviceName!="" AND (serviceName="*;*" OR serviceName="*|*" OR serviceName="*`*" OR serviceName="*$(*")
