⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of pyspider instance allowing attackers to execute arbitrary code, modify or delete projects, and access sensitive data through authenticated user sessions.
Likely Case
Unauthorized modification or deletion of web scraping projects, configuration changes, or data exfiltration through authenticated user actions.
If Mitigated
Limited impact with proper CSRF protections, authentication hardening, and network segmentation in place.
🎯 Exploit Status
Exploitation requires an authenticated user to visit a malicious page. CSRF attacks are well-understood and easy to weaponize.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 0.3.11 or later
Vendor Advisory: https://github.com/binux/pyspider/security/advisories
Restart Required: Yes
Instructions:
1. Upgrade pyspider to version 0.3.11 or later using pip: pip install --upgrade pyspider>=0.3.11
2. Restart all pyspider services
3. Verify the fix by checking the version
🔧 Temporary Workarounds
Implement CSRF Protection
allAdd CSRF tokens to Flask endpoints manually if unable to upgrade immediately
# Requires modifying Flask application code to include CSRF protection
Network Segmentation
linuxRestrict access to pyspider web interface to trusted networks only
# Use firewall rules to limit access: iptables -A INPUT -p tcp --dport 5000 -s trusted_network -j ACCEPT
# iptables -A INPUT -p tcp --dport 5000 -j DROP
🧯 If You Can't Patch
- Implement strict SameSite cookie policies and CORS restrictions
- Use web application firewall (WAF) rules to detect and block CSRF attempts
🔍 How to Verify
Check if Vulnerable:
Check pyspider version: python -c "import pyspider; print(pyspider.__version__)" - if version <= 0.3.10, system is vulnerable.Check Version:
python -c "import pyspider; print(pyspider.__version__)"Verify Fix Applied:
After upgrade, verify version is 0.3.11 or higher and test that CSRF tokens are required for state-changing requests.📡 Detection & Monitoring
Log Indicators:
- Multiple failed state-changing requests from same IP without CSRF tokens
- Unusual project modifications or deletions
Network Indicators:
- HTTP POST requests to pyspider endpoints without Referer headers or CSRF tokens
- Requests originating from unexpected domains
SIEM Query:
source="pyspider" AND (http_method="POST" OR http_method="PUT" OR http_method="DELETE") AND NOT csrf_token=*
