CVE-2020-7633
📋 TL;DR
CVE-2020-7633 is a command injection vulnerability in apiconnect-cli-plugins that allows attackers to execute arbitrary commands on the system by manipulating the pluginUri argument. This affects users of IBM API Connect CLI plugins up to version 6.0.1. Successful exploitation could lead to complete system compromise.
💻 Affected Systems
- IBM API Connect CLI plugins
📦 What is this software?
Apiconnect Cli Plugins by Apiconnect Cli Plugins Project
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise with root/administrator privileges, allowing data theft, ransomware deployment, or persistent backdoor installation.
Likely Case
Unauthorized command execution with the privileges of the user running the CLI, potentially leading to data exfiltration or lateral movement.
If Mitigated
Limited impact if running with minimal privileges in isolated environments with network restrictions.
🎯 Exploit Status
Exploitation requires user interaction to install a malicious plugin, but the injection is straightforward once the attacker controls the pluginUri parameter.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 6.0.2 and later
Vendor Advisory: https://www.ibm.com/support/pages/node/6253781
Restart Required: No
Instructions:
1. Update IBM API Connect CLI to latest version. 2. Run 'npm update -g apiconnect-cli-plugins' to update plugins. 3. Verify version with 'apic --version'.
🔧 Temporary Workarounds
Avoid untrusted plugin sources
allOnly install plugins from trusted, verified sources and avoid using arbitrary plugin URIs.
Run with minimal privileges
allExecute the CLI with non-privileged user accounts to limit potential damage.
🧯 If You Can't Patch
- Implement strict input validation for pluginUri parameters in custom integrations
- Isolate systems running vulnerable versions using network segmentation and access controls
🔍 How to Verify
Check if Vulnerable:
Check installed version with 'npm list -g apiconnect-cli-plugins' and verify if version is 6.0.1 or earlier.
Check Version:
npm list -g apiconnect-cli-plugins | grep apiconnect-cli-plugins
Verify Fix Applied:
After update, confirm version is 6.0.2 or later using 'npm list -g apiconnect-cli-plugins'.
