CVE-2024-37863
📋 TL;DR
A buffer overflow vulnerability in ROS2 Nav2's AMCL process allows remote code execution when processing malicious YAML files. This affects ROS2 Humble distributions using Nav2 navigation stack. Attackers can potentially gain full control of robotic systems.
💻 Affected Systems
- ROS2 Navigation2 (Nav2)
- ROS2 AMCL (Adaptive Monte Carlo Localization)
⚠️ 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.
Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise leading to remote code execution, allowing attackers to take control of robotic platforms, manipulate sensor data, or disable safety systems.
Likely Case
Service disruption through process crashes, potentially causing navigation failures in autonomous systems.
If Mitigated
Limited impact if systems are isolated, use minimal privileges, and validate all configuration inputs.
🎯 Exploit Status
Exploitation requires sending a crafted YAML file to the AMCL process. The vulnerability is in the parsing logic, making exploitation straightforward once the file format is understood.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check ROS Navigation2 repository for specific patched versions
Vendor Advisory: https://github.com/ros-navigation/navigation2/security/advisories
Restart Required: Yes
Instructions:
1. Update ROS2 Navigation2 package via package manager. 2. Update AMCL component specifically. 3. Restart all Nav2-related services. 4. Validate YAML configuration files are from trusted sources.
🔧 Temporary Workarounds
Disable AMCL or restrict YAML input
linuxTemporarily disable AMCL localization or implement strict validation on YAML file inputs
sudo systemctl stop nav2_amcl
Implement input validation in configuration loading
Network isolation
linuxRestrict network access to AMCL service ports
sudo ufw deny from any to any port [AMCL_PORT]
Implement network segmentation
🧯 If You Can't Patch
- Implement strict file validation for all YAML configuration files before processing
- Run AMCL process with minimal privileges and in isolated containers/namespaces
🔍 How to Verify
Check if Vulnerable:
Check ROS2 and Nav2 versions: ros2 pkg list | grep navigation2 && dpkg -l | grep ros-humble-nav2
Check Version:
ros2 pkg version navigation2_amcl
Verify Fix Applied:
Verify updated package versions and test with known safe YAML files
