CVE-2025-6282
📋 TL;DR
This critical path traversal vulnerability in OpenAgents allows attackers to access arbitrary files on the server by manipulating file upload paths. It affects all OpenAgents deployments up to commit ff2e46440699af1324eb25655b622c4a131265bb. The vulnerability exists in the create_upload_file function and has been publicly disclosed.
💻 Affected Systems
- xlang-ai OpenAgents
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete server compromise through reading sensitive files like /etc/passwd, SSH keys, or configuration files, potentially leading to lateral movement and data exfiltration.
Likely Case
Unauthorized access to sensitive files containing credentials, configuration data, or user information stored on the server.
If Mitigated
Limited impact with proper file permission restrictions and input validation preventing directory traversal.
🎯 Exploit Status
Exploit has been publicly disclosed in GitHub issue #141. Path traversal vulnerabilities typically require minimal technical skill to exploit once the technique is known.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown - no official fix released
Vendor Advisory: None available
Restart Required: No
Instructions:
No official patch available. Consider applying community fixes from the GitHub issue or implementing workarounds.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement strict input validation in the create_upload_file function to reject any file paths containing directory traversal sequences (../, ..\)
File System Restrictions
allConfigure the application to run with minimal file system permissions and restrict upload directories to specific, isolated locations
🧯 If You Can't Patch
- Disable or restrict access to the vulnerable file upload endpoint entirely
- Implement a Web Application Firewall (WAF) with rules to detect and block path traversal attempts
🔍 How to Verify
Check if Vulnerable:
Check if your OpenAgents deployment is using commit ff2e46440699af1324eb25655b622c4a131265bb or earlier by examining the git commit history or version metadataCheck Version:
git log --oneline -1Verify Fix Applied:
Test the file upload functionality with path traversal payloads (e.g., '../../etc/passwd') to ensure they are properly rejected📡 Detection & Monitoring
Log Indicators:
- Unusual file access patterns in application logs
- Failed file upload attempts with path traversal sequences
- Access to files outside expected upload directories
Network Indicators:
- HTTP requests containing '../' or similar traversal sequences in file upload parameters
- Unusual file paths in upload requests
SIEM Query:
source="application.log" AND ("../" OR "..\\" OR "%2e%2e%2f") AND "upload"
