CWE-770: Allocation of Resources Without Limits or Throttling
When performing an online tag generation to devices which communicate using the ControlLogix protocol, a machine-in-the-middle, or a device that is not configured correctly, could deliver a response leading to unrestricted or unregulated resource allocation. This could cause a denial-of-service condition and crash the Kepware application. By default, these functions are turned off, yet they remain accessible for users who recognize and require their advantages.
PTC recommends users take a defense-in-depth stance with regards to their manufacturing networks ensuring proper access control is maintained. Additionally, proper adherence to the Kepware Secure Deployment Guide will minimize this threat through accurate configuration and use of the product.
