Meshtastic is an open source, off-grid, decentralized, mesh network built to run on affordable, low-power devices. Meshtastic firmware is an open source firmware implementation for the broader project. The remote hardware module of the firmware does not have proper checks to ensure a remote hardware control message was received should be considered valid. This issue has been addressed in release version 2.5.1. All users are advised to upgrade. There are no known workarounds for this vulnerability.
This vulnerability carries a MEDIUM severity rating with a CVSS v3.1 score of 6.4, indicating it requires adjacent network access but requires specific conditions to be met without requiring user interaction and does not require pre-existing privileges . The vulnerability impacts limited data confidentiality, limited integrity, and availability (service disruption) for affected systems. Impacting 1 product from meshtastic organizations running these solutions should prioritize assessment and patching.
Reported in 2024, this vulnerability emerged during an era marked by increased sophistication in supply chain attacks, cloud infrastructure vulnerabilities, and software-as-a-service (SaaS) security challenges. Security practices during this period emphasized zero-trust architectures, container security, and API protection.
