CVE-2019-1198
An attacker who successfully exploited the vulnerability could run arbitrary code with elevated privileges.
Does this matter?
Lower severity and a low EPSS score (1.94%). Track it; it rarely justifies an emergency change on its own.
Description
An elevation of privilege exists in SyncController.dll. An attacker who successfully exploited the vulnerability could run arbitrary code with elevated privileges. To exploit the vulnerability, an attacker could run a specially crafted application that could exploit the vulnerability. This vulnerability by itself does not allow arbitrary code to be run. However, this vulnerability could be used in conjunction with one or more vulnerabilities (e.g. a remote code execution vulnerability and another elevation of privilege) that could take advantage of the elevated privileges when running. The update addresses the vulnerability by correcting how the SyncController.dll handles processes these requests.
