📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal administrator credentials, hijack user sessions, deface websites, or redirect users to malicious sites, potentially leading to complete system compromise.
Likely Case
Attackers inject malicious scripts to steal user session cookies or credentials, enabling unauthorized access to user accounts and sensitive data.
If Mitigated
With proper input validation and output encoding, the impact is limited to minor data leakage or temporary disruption.
🎯 Exploit Status
XSS vulnerabilities typically require minimal technical skill to exploit once the vulnerable endpoints are identified.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not specified
Vendor Advisory: Not available
Restart Required: No
Instructions:
1. Monitor NASA Fprime GitHub repository for security updates. 2. Apply the official patch when released. 3. Test the patch in a non-production environment first.
🔧 Temporary Workarounds
Implement Input Validation and Output Encoding
allSanitize all user inputs and encode outputs to prevent script injection.
Enable Content Security Policy (CSP)
allConfigure CSP headers to restrict script execution sources.
Add 'Content-Security-Policy' header with appropriate directives in web server configuration.
🧯 If You Can't Patch
- Implement a Web Application Firewall (WAF) with XSS protection rules.
- Disable or restrict access to vulnerable endpoints if possible.
🔍 How to Verify
Check if Vulnerable:
Review NASA Fprime version in your application configuration or package manager. Check for v3.4.3.Check Version:
Check the version in your Fprime configuration file or use package manager commands specific to your deployment.Verify Fix Applied:
After applying mitigations, test with XSS payloads (e.g., <script>alert('test')</script>) to ensure they are properly sanitized.📡 Detection & Monitoring
Log Indicators:
- Unusual script tags or JavaScript in HTTP request logs.
- Multiple failed login attempts or session hijacking alerts.
Network Indicators:
- HTTP requests containing suspicious script payloads.
- Unexpected redirects to external domains.
SIEM Query:
source="web_logs" AND (http_request CONTAINS "<script>" OR http_request CONTAINS "javascript:")
