AgentScope, Path Traversal Vulnerability, CVE-2025-XXXX (Critical)

How the CVE Works:

The CVE-2025-XXXX vulnerability in AgentScope arises from insufficient validation of user-supplied input in the `save-workflow` and `load-workflow` functionalities. Attackers can exploit this by crafting malicious file paths containing traversal sequences (e.g., ../../). When the application processes these paths, it allows unauthorized access to arbitrary JSON files on the filesystem. This can lead to the exposure of sensitive data such as API keys, configuration files, or hardcoded credentials. The vulnerability is critical as it enables both read and write operations, potentially compromising the entire system.

DailyCVE Form:

Platform: AgentScope
Version: Prior to fix
Vulnerability: Path Traversal
Severity: Critical
Date: Mar 20, 2025

What Undercode Say:

Exploitation:

1. Craft Malicious Path: Use `../../` sequences to traverse directories.

   payload = "../../etc/passwd"
   

2. Exploit via API: Send crafted payload to `save-workflow` or `load-workflow` endpoints.

   import requests
   url = "http://target.com/save-workflow"
   payload = {"file": "../../etc/passwd"}
   response = requests.post(url, json=payload)
   print(response.text)
   

3. Exfiltrate Data: Access sensitive files or overwrite critical configurations.

Protection:

1. Input Validation: Sanitize user inputs to prevent traversal sequences.

   import os
   def sanitize_path(user_input):
   base_dir = "/safe/directory"
   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: Employ libraries like `werkzeug.utils.secure_filename` for file handling.

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

3. File Permissions: Restrict file access to minimal required permissions.

   chmod 600 /path/to/sensitive/files
   

4. Patch Update: Upgrade to the latest version of AgentScope that addresses this vulnerability.

   pip install --upgrade modelscope
   

Detection:

1. Log Monitoring: Check logs for unusual file access patterns.

   grep "save-workflow" /var/log/agentscope.log
   

2. Static Analysis: Use tools like Bandit to detect insecure code.

   bandit -r /path/to/code
   

Mitigation:

1. Web Application Firewall (WAF): Deploy WAF rules to block traversal attempts.

   location /save-workflow {
   if ($request_uri ~ "..") {
   return 403;
   }
   }
   

2. Regular Audits: Conduct periodic security reviews of file handling mechanisms.
