CVE-2024-37860
📋 TL;DR
A buffer overflow vulnerability in ROS2 navigation2 allows local attackers to execute arbitrary code by providing a malicious .yaml file to the nav2_amcl process. This affects ROS2 Humble installations using the navigation2 package. Attackers with local access can potentially gain elevated privileges or compromise the robotic system.
💻 Affected Systems
- ROS2 navigation2 package
⚠️ Manual Verification Required
This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.

- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with root privileges, allowing attacker to take full control of robotic system, modify navigation parameters, or exfiltrate sensitive data.
Likely Case
Local privilege escalation leading to unauthorized control of robotic navigation functions, potential denial of service, or manipulation of robot behavior.
If Mitigated
Limited impact with proper access controls and file validation, potentially causing process crashes but no code execution.
🎯 Exploit Status
Exploitation requires local access and ability to provide malicious YAML file to the nav2_amcl process. References show multiple GitHub issues discussing the vulnerability.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check navigation2 repository for latest fixes
Vendor Advisory: https://github.com/ros-navigation/navigation2/issues/4005
Restart Required: Yes
Instructions:
1. Update navigation2 package: sudo apt update && sudo apt upgrade ros-humble-navigation2
2. Restart nav2_amcl processes
3. Verify no custom YAML files contain malicious content
🔧 Temporary Workarounds
Restrict YAML file access
linuxLimit who can provide YAML files to nav2_amcl process and validate all input files
chmod 600 /path/to/nav2/config/*.yaml
chown root:root /path/to/nav2/config/*.yaml
Run with reduced privileges
linuxExecute nav2_amcl with non-root user privileges to limit impact
sudo -u rosuser ros2 run nav2_amcl amcl
🧯 If You Can't Patch
- Implement strict file permissions on YAML configuration directories
- Use application allowlisting to prevent unauthorized processes from interacting with nav2_amcl
🔍 How to Verify
Check if Vulnerable:
Check if using ROS2 Humble with navigation2 package and review YAML file handling in nav2_amclCheck Version:
apt list --installed | grep ros-humble-navigation2Verify Fix Applied:
Verify navigation2 package version is updated and test with known safe YAML files📡 Detection & Monitoring
Log Indicators:
- nav2_amcl process crashes
- unusual memory access patterns in system logs
- unexpected YAML file parsing errors
Network Indicators:
- Local process communication anomalies with nav2_amcl
