CVE-2024-8451Network attack vector

Unauthenticated SSH denial of service via connection-slot exhaustion

Published Sep 30, 2024 · Updated Sep 30, 2024

Denial of service in the SSH service of PLANET Technology GS-4210 switches allows remote attackers to block legitimate SSH access. The SSH service accepts insufficiently authenticated connection requests into its finite connection-slot pool, allowing those requests to occupy every slot. No credentials or user interaction are required, and the reported consequence is limited to interruption of legitimate SSH access.
