Unauthenticated information disclosure via uninitialized resource use
Published Oct 13, 2026 · Updated Oct 13, 2026
Information disclosure in Microsoft Windows RRAS allows remote attackers to read information through the network-facing service. RRAS uses an uninitialized resource, but the public CNA record does not identify the resource, request handler, or triggering input. Exploitation requires network access to the affected service, not credentials or user interaction; no data modification or service interruption is described.
