Microsoft Utility Manager is prone to a local privilege escalation vulnerability. It is reported that a local user may influence the Utility Manager into executing an attacker-supplied application with elevated privileges. The cause of this issue is that the Utility Manager will attempt to load context sensitive help without dropping privileges. A local attacker may exploit this vulnerability to gain SYSTEM level privileges on the computer. This vulnerability is similar to the issue reported in BID 10124. The vendor fixes for BID 10124 addressed the issue by removing access to context sensitive help from the Utility Manager GUI. However, the functionality to access context sensitive help is still present in the Utility Manager application itself.
