CVE-2024-41648 is a vulnerability identified in the ROS2 navigation2 package, specifically within the nav2_regulated_pure_pursuit_controller module. This component is responsible for controlling robot navigation behavior using a pure pursuit algorithm regulated by certain parameters. The vulnerability stems from insecure permissions that allow an attacker with low privileges (PR:L) to execute arbitrary code remotely (AV:N) by submitting a crafted script to this controller. The attack complexity is low (AC:L), and no user interaction is required (UI:N), making exploitation feasible in environments where an attacker has some level of access to the network or system. The vulnerability is classified under CWE-281, which relates to improper authorization, indicating that the affected component does not correctly enforce permission checks before executing scripts. The CVSS v3.1 base score is 7.1 (high severity), reflecting a high impact on confidentiality (C:H), limited impact on integrity (I:L), and no impact on availability (A:N). While no public exploits have been reported yet, the potential for arbitrary code execution could allow attackers to compromise robotic systems, steal sensitive data, or manipulate robot behavior. The lack of available patches at the time of publication necessitates immediate attention to permissions and access controls within affected ROS2 deployments.

The vulnerability allows attackers to execute arbitrary code remotely with low complexity, potentially compromising the confidentiality of robotic systems running ROS2 navigation2. This could lead to unauthorized data access, manipulation of robot navigation behavior, or insertion of malicious code into robotic workflows. Although the integrity impact is limited and availability is unaffected, the ability to run arbitrary code can serve as a foothold for further attacks or espionage. Organizations deploying ROS2 in industrial automation, autonomous vehicles, logistics, or research environments face risks of operational disruption, intellectual property theft, and safety hazards. The threat is particularly critical for environments where robots operate in sensitive or mission-critical roles, such as manufacturing plants, defense applications, or healthcare robotics. The absence of known exploits currently reduces immediate risk but does not diminish the urgency for mitigation given the high severity score and ease of exploitation.

1. Immediately review and tighten permissions for the nav2_regulated_pure_pursuit_controller component and related ROS2 navigation2 modules to ensure only authorized users and processes can submit scripts. 2. Implement strict input validation and sanitization for any scripts or commands accepted by the navigation controller to prevent injection of malicious code. 3. Employ network segmentation and access controls to limit exposure of ROS2 systems to untrusted networks or users. 4. Monitor logs and system behavior for unusual script execution or unauthorized access attempts within ROS2 environments. 5. Stay updated with Open Robotics advisories and apply patches or updates as soon as they become available. 6. Consider deploying runtime application self-protection (RASP) or endpoint detection and response (EDR) solutions tailored for robotic systems to detect and block suspicious activities. 7. Conduct regular security audits and penetration testing focused on robotic operating systems and navigation components to identify and remediate similar permission issues proactively.
