OneDrive for Windows Elevation of Privilege Vulnerability

An elevation of privilege vulnerability exists when the OneDrive for Windows Desktop application improperly handles symbolic links. An attacker who successfully exploited this vulnerability could overwrite a targeted file with an elevated status.

To exploit this vulnerability, an attacker would first have to log on to the system. An attacker could then run a specially crafted application that could exploit the vulnerability and delete a targeted file with an elevated status.

The update addresses this vulnerability by correcting where the OneDrive updater performs file writes while running with elevation.
