CVE-2024-10831
📋 TL;DR
This vulnerability allows attackers to upload arbitrary files to any location on the server by exploiting path traversal in the file upload endpoint. Attackers can overwrite critical system files like SSH keys to gain persistent access. All users running the vulnerable version of db-gpt are affected.

📦 What is this software?
Db Gpt by Dbgpt
⚠️ Risk & Real-World Impact
Worst Case
Complete server compromise through overwriting SSH keys or system binaries, leading to data theft, ransomware deployment, or use as attack infrastructure.
Likely Case
Unauthorized file uploads to sensitive directories, potentially enabling backdoor installation, data exfiltration, or service disruption.
If Mitigated
Limited impact with proper file permission restrictions and network segmentation, though the vulnerability still exists.
🎯 Exploit Status
Exploitation requires access to the file upload endpoint but is straightforward once authenticated.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 0.6.1 or later
Vendor Advisory: https://huntr.com/bounties/5c34c39f-66d4-414c-ab6a-f7888a5d882a
Restart Required: Yes
Instructions:
1. Update to version 0.6.1 or later. 2. Restart the db-gpt service. 3. Verify the fix by testing file upload functionality.
🔧 Temporary Workarounds
Restrict file upload permissions
linuxConfigure the application to run with minimal privileges and restrict write access to necessary directories only.
chmod 755 /path/to/upload/directory
chown www-data:www-data /path/to/upload/directory
Implement file path validation
allAdd server-side validation to reject file paths containing directory traversal sequences like '../'.
🧯 If You Can't Patch
- Disable file upload functionality entirely if not required.
- Implement strict network access controls to limit who can reach the upload endpoint.
🔍 How to Verify
Check if Vulnerable:
Check if running version 0.6.0 and test file upload with a path traversal payload (e.g., '../../etc/passwd').Check Version:
Check the application version in the web interface or configuration files.Verify Fix Applied:
After updating, attempt the same path traversal test; it should be rejected.📡 Detection & Monitoring
Log Indicators:
- Unusual file upload attempts with '../' sequences in filenames
- Failed or successful uploads to non-standard directories
Network Indicators:
- HTTP POST requests to upload endpoints with suspicious filenames
SIEM Query:
source="web_logs" AND (uri_path="/upload" OR uri_path="/api/upload") AND (filename="*../*" OR file_key="*../*")
