Security readout for executives and security teams

This is an old local denial-of-service issue in NCP Network Communication Secure Client 8.11 Build 146, with other versions only described as possible. A local user could make ncprwsnt.exe consume CPU. Business impact is mainly endpoint disruption where this legacy client is still installed. Exposure appears limited to endpoints running NCP Network Communication Secure Client 8.11 Build 146, and possibly other versions, where an untrusted or compromised local user can execute the affected component. Treat this as a legacy exposure cleanup item, not an emergency, unless the client remains deployed on sensitive shared systems or kiosks where local misuse could disrupt operations. Mitigation focus: Inventory endpoints for NCP Network Communication Secure Client installations.; Check vendor guidance for fixed or supported versions.; Remove or replace unsupported legacy VPN/PKI clients where possible..
