CVE-2024-37863
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 · uneditedOpen Robotics Robotic Operating System 2 (ROS2) and Nav2 humble versions were discovered to contain a buffer overflow via the nav2_amcl process. This vulnerability is triggered via sending a crafted .yaml file.
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 nav2_amcl process of ROS2 and Nav2 humble versions. The vulnerability is triggered when nav2_amcl parses a maliciously crafted .yaml configuration file, potentially allowing arbitrary code execution or denial of service due to 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.
-
Confirm nav2_amcl node is runningRun 'ros2 node list' or 'ros2 node info /amcl' to see if the nav2_amcl node is active in the ROS2 environmentAffected if nav2_amcl process is currently executing in the ROS2 system
-
Identify Nav2 package versionRun 'ros2 pkg version nav2_amcl' or check the installed nav2_amcl package version via the package manager (apt list --installed | grep nav2)Affected if The installed version corresponds to Nav2 humble branch (check if version is in the humble release timeline)
-
Locate YAML configuration files used by nav2_amclInspect the launch file or parameter file that starts nav2_amcl; look for 'params' or 'param_file' arguments pointing to .yaml files, typically in /opt/ros/humble/share/nav2_amcl or custom config directoriesAffected if nav2_amcl is loading .yaml configuration files from any location
-
Verify source of configuration filesExamine ownership and access permissions of the .yaml files identified in step 3; check if they reside in world-writable directories or are pulled from untrusted sourcesAffected if Configuration files are writable by untrusted users or originate from untrusted locations
-
Check for custom parameter overridesReview launch files and startup scripts for command-line parameter overrides or additional YAML files merged into the nav2_amcl configurationAffected if Custom parameters or multiple YAML files are being loaded beyond the default configuration
The environment is affected if nav2_amcl is running with Nav2 humble and loads .yaml configuration files, especially from locations with relaxed access controls.

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 dataApply available security patches for Nav2 humble when released. Until patches are available, restrict access to systems running nav2_amcl and validate all .yaml configuration files before deployment.
