CVE-2024-47870
📋 TL;DR
A race condition in Gradio's update_root_in_config function allows attackers to redirect frontend-backend communication to malicious servers. This could intercept sensitive data like credentials or uploaded files. All Gradio users, especially those with internet-exposed servers, are affected.
💻 Affected Systems
- gradio
📦 What is this software?
Gradio by Gradio Project
⚠️ Risk & Real-World Impact
Worst Case
Complete interception of all user data including authentication credentials, session tokens, and uploaded files, leading to account compromise and data theft.
Likely Case
Selective interception of user sessions and file uploads when attackers successfully exploit the race condition window.
If Mitigated
Limited impact with proper network segmentation and monitoring, though the vulnerability still exists.
🎯 Exploit Status
Exploitation requires precise timing to win the race condition, but no authentication is needed to attempt exploitation.
