Technical details
The vulnerability is classified as CWE-770 (Allocation of Resources Without Limits or Throttling) within the OPC-UA Server of the ABB PPT30 Operating System. It stems from a failure to properly limit or throttle resource consumption, which can be triggered by an unauthenticated attacker via the network. Successful exploitation allows the attacker to exhaust system resources, leading to a permanent denial-of-service (DoS) that prevents legitimate users from interacting with the service. The issue is addressed in PPT30 Operating System version 1.8.0.
