Impacted is the function ssh_exec of the file src/index.ts of the component SSH Command Handler. Performing a manipulation of the argument host/username results in command injection. The attack requires a local approach. The actual existence of this vulnerability is currently in question. This product adopts a rolling release strategy to maintain continuous delivery. Therefore, version details for affected or updated releases cannot be specified.
