CVE-2025-25372
📋 TL;DR
CVE-2025-25372 is a memory corruption vulnerability in NASA cFS Aquila's Memory Management Module that allows remote attackers to cause a segmentation fault via malicious telecommands. This affects systems running NASA's Core Flight System Aquila version, potentially disrupting flight software operations. The vulnerability requires access to send telecommands to the affected module.
💻 Affected Systems
- NASA Core Flight System (cFS) Aquila
📦 What is this software?
Cfs by Nasa
⚠️ Risk & Real-World Impact
Worst Case
Complete system crash leading to loss of spacecraft/vehicle control, mission failure, or system reboot in critical flight operations.
Likely Case
Service disruption of the Memory Management Module causing system instability, potential data corruption, and requiring manual intervention.
If Mitigated
Contained segmentation fault within the module with proper fault tolerance mechanisms preventing system-wide impact.
🎯 Exploit Status
Requires knowledge of telecommand protocols and ability to send crafted commands to the Memory Management Module.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not specified in provided references
Vendor Advisory: https://visionspace.com/nasa-cfs-version-aquila-software-vulnerability-assessment/
Restart Required: No
Instructions:
1. Obtain patched version from NASA cFS repository. 2. Update Memory Management Module code. 3. Validate telecommand input validation. 4. Test in non-production environment first.
🔧 Temporary Workarounds
Telecommand Filtering
allImplement network filtering to restrict telecommand sources to authorized ground stations only.
Module Isolation
allConfigure system to run Memory Management Module with reduced privileges and in isolated process space.
🧯 If You Can't Patch
- Implement strict telecommand authentication and authorization controls
- Deploy intrusion detection monitoring for anomalous telecommand patterns
🔍 How to Verify
Check if Vulnerable:
Check if running NASA cFS Aquila version with vulnerable Memory Management Module by reviewing system configuration and version information.Check Version:
Check cFS version through system telemetry or configuration files (specific command depends on implementation).Verify Fix Applied:
Test telecommand handling with malformed inputs to ensure proper error handling without segmentation faults.📡 Detection & Monitoring
Log Indicators:
- Segmentation fault logs from Memory Management Module
- Unexpected process termination
- Telecommand parsing errors
Network Indicators:
- Unusual telecommand patterns
- Telecommands from unauthorized sources
- High frequency of malformed commands
SIEM Query:
process:segfault AND module:"Memory Management" OR telecommand:malformed
