Link-following privilege escalation in Microsoft PC Manager before 3.17.4 allows local users to gain elevated privileges. Microsoft has not disclosed the affected file-handling locus or the specific file operation that follows an attacker-controlled link. Exploitation requires low-privileged local access; the resulting elevated privileges permit access to, modification of, or disruption of protected resources.
