CVE-2024-30963
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedBuffer Overflow vulnerability in Open Robotics Robotic Operating System 2 (ROS2) navigation2- ROS2-humble and navigation 2-humble allows a local attacker to execute arbitrary code via a crafted script.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA buffer overflow vulnerability exists in the ROS2 navigation2-humble package that allows a local attacker to execute arbitrary code via a crafted script. The vulnerability stems from improper bounds checking when processing navigation scripts, enabling controlled memory corruption.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify ROS2 navigation2-humble is installedRun 'ros2 pkg list | grep navigation2' or check package manager (apt list --installed 2>/dev/null | grep navigation2-humble)Affected if The navigation2-humble package is present in the system
-
Determine installed version of navigation2-humbleRun 'ros2 pkg version navigation2_humble' or check via 'dpkg -l | grep navigation2-humble' on Debian-based systemsAffected if Version cannot be determined or falls within an unpatched release range
-
Identify navigation script processing componentsInspect running nodes via 'ros2 node list' and check for navigation-related nodes (e.g., planner, controller, server components). Review launch files in /opt/ros/humble/share/navigation2/launch/ or custom launch directoriesAffected if Navigation2 nodes are running and processing scripts from accessible locations
-
Check script execution permissions on navigation directoriesReview file permissions on navigation2 configuration directories (typically /opt/ros/humble/share/navigation2/ and ~/.ros/ or workspace dirs). Run 'ls -la' on these paths to verify who can write scriptsAffected if Non-privileged users have write access to directories where navigation scripts are loaded from
-
Monitor for suspicious navigation script activityAudit recent file creation/modification in navigation2 workspaces: 'find ~/.ros/ -name "*.py" -mtime -7' or check system audit logs for unexpected script executionAffected if Unknown or untrusted scripts exist in navigation script directories
If navigation2-humble is installed and processes scripts from locations writable by local users, the environment is potentially affected by this buffer overflow vulnerability.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpdate navigation2-humble to the latest patched version released by Open Robotics. If patching is not immediately possible, restrict local script execution permissions and monitor for unauthorized script activity.
