AI-suggested

1. Monitor RT-Thread vendor channels and security advisories for official patches addressing CVE-2024-25393 and apply them immediately upon release. 2. In the interim, restrict network access to devices running RT-Thread, especially limiting exposure of the AT command server component to untrusted networks. 3. Employ network segmentation and firewall rules to isolate vulnerable embedded devices from critical infrastructure and sensitive networks. 4. Implement intrusion detection and prevention systems (IDS/IPS) with signatures or anomaly detection capable of identifying malformed AT command packets or unusual traffic patterns targeting the at_server component. 5. Conduct thorough inventory and asset management to identify all RT-Thread deployments within the organization, including embedded and IoT devices. 6. Where possible, disable or limit the functionality of the AT command server if not required for device operation. 7. Engage with device manufacturers to confirm patch availability and timelines, and request security updates if none are forthcoming. 8. Prepare incident response plans tailored to embedded device compromise scenarios to enable rapid containment and recovery.

Description

A stack buffer overflow occurs in net/at/src/at_server.c in RT-Thread through 5.0.2.
