Executive Summary

A remote code execution vulnerability exists in Microsoft Dynamics 365 (on-premises) when the server fails to properly sanitize web requests to an affected Dynamics server. An attacker who successfully exploited the vulnerability could run arbitrary code in the context of the SQL service account. An authenticated attacker could exploit this vulnerability by sending a specially crafted request to a vulnerable Dynamics server. The security update addresses the vulnerability by correcting how Microsoft Dynamics 365 (on-premises) validates and sanitizes user input.
