Link-following in Microsoft PC Manager before 3.21.6.0 allows local users to elevate privileges through crafted filesystem links. Microsoft identifies improper link resolution before file access but does not disclose the affected file operation or code path. Exploitation requires an authenticated local user and can grant elevated privileges on the same Windows host.
