CVE-2024-30963
📋 TL;DR
A buffer overflow vulnerability in ROS2 navigation2 allows local attackers to execute arbitrary code by providing a malicious script. This affects systems running ROS2 Humble navigation2 packages, potentially compromising robotic systems and adjacent networks.
💻 Affected Systems
- ROS2 navigation2
- ROS2 Humble navigation2
⚠️ 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).

- Check vendor security advisories for your specific version
- Test if the vulnerability is exploitable in your environment
- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise leading to unauthorized control of robotic systems, data exfiltration, or lateral movement to other networked devices.
Likely Case
Local privilege escalation allowing attacker to gain elevated permissions on the affected ROS2 system.
If Mitigated
Limited impact if proper network segmentation and least privilege principles are implemented.
🎯 Exploit Status
Requires local access and ability to execute crafted scripts; buffer overflow exploitation requires specific knowledge of the target system.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check GitHub issue #4157 for specific patched version
Vendor Advisory: https://github.com/ros-planning/navigation2/issues/4157
Restart Required: Yes
Instructions:
1. Check current navigation2 version
2. Update navigation2 package via ROS2 package manager
3. Restart ROS2 nodes and navigation2 services
🔧 Temporary Workarounds
Restrict script execution
linuxLimit execution of scripts to trusted sources only
chmod -x /path/to/scripts/*
setfacl -m u:rosuser:r-- /path/to/scripts/
🧯 If You Can't Patch
- Implement strict access controls to limit local user access to ROS2 systems
- Network segment ROS2 systems from critical infrastructure
🔍 How to Verify
Check if Vulnerable:
Check navigation2 package version and compare against patched version in GitHub issueCheck Version:
ros2 pkg list | grep navigation2 && apt show ros-humble-navigation2Verify Fix Applied:
Verify navigation2 package is updated to patched version and test script execution functionality📡 Detection & Monitoring
Log Indicators:
- Unusual script execution patterns
- Process crashes in navigation2 components
- Unexpected privilege escalation attempts
Network Indicators:
