A vulnerability has been identified in CPCI85 Central Processing/Communication (All versions < V26.10), RTUM85 RTU Base (All versions < V26.10). The affected application contains denial-of-service (DoS) vulnerability. The remote operation mode is susceptible to a resource exhaustion condition when subjected to a high volume of requests.
