CVE-2024-46891Network attack vector

Service interruption via unrestricted log growth

Published Nov 12, 2024 · Updated Nov 12, 2024

Uncontrolled resource consumption in Siemens SINEC INS before V1.0 SP2 Update 3 allows remote attackers to interrupt service. The application permits remotely generated events to expand log files without an effective size restriction until host resources are exhausted. No authentication or user interaction is required; sustained event generation can consume host resources and deny service.
