CVE-2023-6572
📋 TL;DR
This CVE describes a command injection vulnerability in the Gradio library that allows attackers to execute arbitrary commands on the host system. It affects applications using vulnerable versions of Gradio that process untrusted user input. Attackers can exploit this to gain unauthorized access and control over affected systems.
💻 Affected Systems
- gradio
📦 What is this software?
Gradio by Gradio Project
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise allowing remote code execution, data theft, lateral movement, and complete control of the host.
Likely Case
Unauthorized command execution leading to data exfiltration, service disruption, or installation of malware.
If Mitigated
Limited impact with proper input validation and sandboxing, potentially only service disruption.
🎯 Exploit Status
Exploitation requires sending specially crafted input to vulnerable endpoints. Public details available in bounty reports.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Fixed in commit 5b5af1899dd98d63e1f9b48a93601c2db1f56520 and later versions
Vendor Advisory: https://github.com/gradio-app/gradio/commit/5b5af1899dd98d63e1f9b48a93601c2db1f56520
Restart Required: Yes
Instructions:
1. Update Gradio to latest version: pip install --upgrade gradio
2. Restart all applications using Gradio
3. Verify the fix by checking version and testing input validation
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement strict input validation and sanitization for all user inputs before processing.
Network Segmentation
allIsolate Gradio applications in restricted network segments with limited outbound access.
🧯 If You Can't Patch
- Implement strict input validation and sanitization for all user inputs
- Run Gradio applications with minimal privileges and in isolated containers
🔍 How to Verify
Check if Vulnerable:
Check Gradio version and compare with fixed commit 5b5af1899dd98d63e1f9b48a93601c2db1f56520Check Version:
python -c "import gradio; print(gradio.__version__)"Verify Fix Applied:
Test with malicious input patterns that previously triggered command injection📡 Detection & Monitoring
Log Indicators:
