Summary
Impact: Elevation of Privilege. Microsoft rating: Important. Not known to be exploited — Exploitation Less Likely. Customer action: Required.
Details
According to the CVSS metric, user interaction is required (UI:R) and privileges required is Low (PR:L). What does that mean for this vulnerability?
A non-admin local user who has sufficient permissions to create symbolic links on a Windows computer that has Azure Connected Machine Agent installed (or before the agent is installed) could create links from a directory used by the agent to other privileged files on the computer. If the administrator later installs virtual machine extensions on the machine, those files could be deleted.
What privileges could an attacker gain with successful exploitation?
An attacker who successfully exploited the vulnerability could add symlinks and cause an arbitrary file delete as SYSTEM.
