CVE-2024-57609
📋 TL;DR
A code injection vulnerability in Pygwalker's login redirection function allows attackers to execute arbitrary code and access sensitive information by manipulating the redirect_path parameter. This affects all users running Pygwalker versions before 0.4.9.9. Remote attackers can exploit this without authentication to compromise affected systems.

- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise with remote code execution leading to data theft, lateral movement, and persistent backdoor installation.
Likely Case
Sensitive information disclosure and limited code execution within the application context, potentially leading to credential theft and further exploitation.
If Mitigated
Attack blocked at perimeter with proper input validation and network segmentation, limiting impact to isolated application component.
🎯 Exploit Status
Exploitation requires crafting malicious redirect_path parameter but no authentication is needed. The GitHub reference suggests proof-of-concept details are available.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 0.4.9.9 and later
Vendor Advisory: Not specified in provided references
Restart Required: No
Instructions:
1. Update Pygwalker to version 0.4.9.9 or later using pip: pip install --upgrade pygwalker>=0.4.9.9
2. Verify the update completed successfully
3. Test login functionality to ensure no regression
🔧 Temporary Workarounds
Input Validation Filter
allImplement server-side validation to sanitize redirect_path parameter before processing
Implement regex filter: ^[a-zA-Z0-9\/\-\._]+$ for redirect_path values
Web Application Firewall Rule
allBlock requests containing suspicious patterns in redirect_path parameter
WAF rule to block: redirect_path containing ';', '|', '&', '$', '(', ')', '{', '}'
🧯 If You Can't Patch
- Isolate Pygwalker instances behind strict network segmentation with no internet access
- Implement reverse proxy with strict input validation for all redirect_path parameters
🔍 How to Verify
Check if Vulnerable:
Check Pygwalker version: python -c "import pygwalker; print(pygwalker.__version__)" and compare to 0.4.9.9Check Version:
python -c "import pygwalker; print('Pygwalker version:', pygwalker.__version__)"Verify Fix Applied:
After update, verify version is 0.4.9.9 or higher and test login redirection with various inputs📡 Detection & Monitoring
Log Indicators:
- Unusual redirect_path parameter values in login requests
- Multiple failed login attempts with crafted redirect parameters
- Application errors related to redirect processing
Network Indicators:
- HTTP requests with suspicious characters in redirect_path parameter
- Unexpected outbound connections from Pygwalker instances
SIEM Query:
source="*pygwalker*" AND (redirect_path="*;*" OR redirect_path="*|*" OR redirect_path="*$*" OR redirect_path="*&*" OR redirect_path="*`*")
