CVE-2024-41118 – This vulnerability in streamlit-geospatial allo... (How to Fix)

Q: What is the severity of CVE-2024-41118?

CVE-2024-41118 has a CVSS score of 7.5 (HIGH). This vulnerability in streamlit-geospatial allows blind server-side request forgery (SSRF) where user-controlled URLs are passed to a Web Map Service function without proper validation. Attackers can make the application send HTTP requests to arbitrary internal or external destinations, potentially accessing sensitive systems. Users running streamlit-geospatial versions before the fix are affected.

📋 TL;DR

This vulnerability in streamlit-geospatial allows blind server-side request forgery (SSRF) where user-controlled URLs are passed to a Web Map Service function without proper validation. Attackers can make the application send HTTP requests to arbitrary internal or external destinations, potentially accessing sensitive systems. Users running streamlit-geospatial versions before the fix are affected.

⚠️ Risk & Real-World Impact

🔴

Worst Case

Attackers could use the SSRF to access internal services, exfiltrate sensitive data from internal networks, or perform port scanning of internal infrastructure.

🟠

Likely Case

Attackers probe internal services, potentially accessing metadata services or other unprotected internal endpoints to gather information about the environment.

🟢

If Mitigated

With proper input validation and network segmentation, impact is limited to failed external requests or access to non-sensitive endpoints.

🌐 Internet-Facing: HIGH

🏢 Internal Only: MEDIUM

🎯 Exploit Status

Public PoC: ✅ No

Weaponized: UNKNOWN

Unauthenticated Exploit: ⚠️ Yes

Complexity: LOW

Exploitation requires access to the Web Map Service page but no authentication. The SSRF is blind, meaning attackers don't see response content directly.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Commit c4f81d9616d40c60584e36abb15300853a66e489

Vendor Advisory: https://securitylab.github.com/advisories/GHSL-2024-100_GHSL-2024-108_streamlit-geospatial/

Restart Required: Yes

Instructions:

1. Update to the latest version of streamlit-geospatial that includes commit c4f81d9616d40c60584e36abb15300853a66e489. 2. Restart the streamlit application. 3. Verify the fix by checking that URL validation is now implemented.

🔧 Temporary Workarounds

Input Validation Filter

all

Implement URL validation to restrict allowed domains or patterns before passing to get_wms_layer function.

# Add validation in pages/7_📦_Web_Map_Service.py before line 47
# Example: if not url.startswith('https://allowed-domain.com/'): raise ValueError('Invalid URL')

Network Restriction

linux

Use firewall rules to restrict outbound connections from the streamlit application server.

# Example iptables rule to restrict outbound HTTP/HTTPS
iptables -A OUTPUT -p tcp --dport 80 -j DROP
iptables -A OUTPUT -p tcp --dport 443 -j DROP

🧯 If You Can't Patch

Disable or remove the Web Map Service page (pages/7_📦_Web_Map_Service.py) from the application.
Implement a web application firewall (WAF) with SSRF protection rules to block malicious URL patterns.

🔍 How to Verify

Check if Vulnerable:

Check if your streamlit-geospatial version includes commit c4f81d9616d40c60584e36abb15300853a66e489. Review pages/7_📦_Web_Map_Service.py line 47 to see if URL validation is implemented.

Check Version:

git log --oneline | grep c4f81d9616d40c60584e36abb15300853a66e489

Verify Fix Applied:

Test the Web Map Service page with malicious URLs (like http://169.254.169.254/) and verify they are rejected or properly validated.

📡 Detection & Monitoring

Log Indicators:

Unusual outbound HTTP requests from the streamlit application to internal IP addresses or unexpected domains
Failed URL validation attempts in application logs

Network Indicators:

HTTP requests from the streamlit server to internal metadata services (169.254.169.254, 192.168.0.0/16 ranges)
Unexpected outbound traffic patterns from the application server

SIEM Query:

source="streamlit-app" AND (dest_ip=169.254.169.254 OR dest_ip IN [192.168.0.0/16, 10.0.0.0/8, 172.16.0.0/12])
