CVE-2025-25373
📋 TL;DR
The Memory Management Module in NASA cFS Aquila has insecure permissions that allow attackers to gain remote code execution on affected systems. This vulnerability affects all systems running NASA cFS Aquila with the vulnerable memory management configuration. Attackers can exploit this to take complete control of affected flight systems.
💻 Affected Systems
- NASA Core Flight System (cFS) Aquila
📦 What is this software?
Cfs by Nasa
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing attackers to execute arbitrary code, modify flight control systems, disrupt operations, and potentially cause physical damage to spacecraft or satellites.
Likely Case
Unauthorized access to flight system memory leading to data exfiltration, system manipulation, and disruption of critical space operations.
If Mitigated
Limited impact through proper segmentation and access controls, potentially allowing only information disclosure without code execution.
🎯 Exploit Status
Exploitation requires access to the system but no authentication. Complexity is medium due to specialized nature of space systems.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check NASA cFS Aquila security advisory for specific patched version
Vendor Advisory: https://visionspace.com/nasa-cfs-version-aquila-software-vulnerability-assessment/
Restart Required: Yes
Instructions:
1. Review NASA security advisory 2. Obtain patched version from NASA cFS repository 3. Apply memory management module security updates 4. Restart affected systems 5. Verify permissions are properly configured
🔧 Temporary Workarounds
Memory Permission Hardening
allManually configure strict memory permissions and access controls for the memory management module
# Configure memory module permissions according to NASA security guidelines
# Set restrictive access controls on memory management interfaces
Network Segmentation
allIsolate cFS systems from untrusted networks and implement strict network access controls
# Implement firewall rules to restrict access to cFS systems
# Configure network segmentation for space systems
🧯 If You Can't Patch
- Implement strict network segmentation and isolate affected systems
- Deploy additional monitoring and anomaly detection for memory access patterns
🔍 How to Verify
Check if Vulnerable:
Review memory management module configuration and permissions in NASA cFS Aquila deploymentCheck Version:
# Check cFS Aquila version through system configuration or NASA-provided verification toolsVerify Fix Applied:
Verify memory permissions are properly configured and test for unauthorized memory access attempts📡 Detection & Monitoring
Log Indicators:
- Unauthorized memory access attempts
- Abnormal memory permission changes
- Unexpected process execution in memory management context
