Vulnerability in Microsoft Malware Protection Engine Could Allow Elevation of Privilege

Microsoft has just issued an advisory about a vulnerability in the Microsoft Malware Protection Engine. If the said flaw is exploited, elevated privileges are granted to a local user once the engine starts to scan after a system is infiltrated by an attacker using valid login credentials and has created a specially crafted registry key. This, in turn, may grant the attacker the same privileges as the local user. Microsoft has also found that anonymous users could not exploit this vulnerability.
