Unauthenticated remote code execution
Published Mar 14, 2023 · Updated Jan 1, 2025
Remote code execution in Microsoft Windows RPC Runtime allows remote attackers to execute code via unspecified network vectors. Microsoft has not disclosed the affected function or how the published integer underflow arises while RPC Runtime processes untrusted input. No credentials or user interaction are required, and successful exploitation runs attacker-controlled code on the affected system.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=10.0.10240.0 <10.0.10240.19805
