# Eclipse Mnestix AAS Generator: unbounded count lets remote callers exhaust memory

Eclipse Mnestix AAS Generator versions 0.1.0 up to 1.5.0 do not cap the count parameter on the submodel ID generation endpoints. A remote unauthenticated caller can request a huge count, making the service hold identifiers in memory until it runs out and stops responding.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the version of Mnestix AAS Generator deployed, looking for any build below `1.5.0`
- Confirm whether the GET `/api/v1/IdGenerator/submodelIds/{count}` or `/api/v2/IdGenerator/submodelIds/{count}` endpoints are reachable from the network

## Fix

- Move Mnestix AAS Generator to `1.5.0` or later

## Timeline

## From the sources

In Eclipse Mnestix AAS Generator versions 0.1.0 up until but excluding 1.5.0, a practical upper bound on the client-supplied count parameter of the GET /api/v1/IdGenerator/submodelIds/{count} and GET /api/v2/IdGenerator/submodelIds/{count} endpoints is not enforced. The service generates and retains identifiers in memory before returning a response. A remote unauthenticated attacker can submit a large count to cause excessive memory consumption, potentially resulting in denial of service. Exploitation requires network access to the endpoint and successful retrieval of the ID-generation configuration from the configured backend repository.
