A getfile function in MDT AutoSave versions prior to v6.02.06 enables a user to supply an optional parameter, resulting in the processing of a request in a special manner. This can result in the execution of an unzip command and place a malicious .exe file in one of the locations the function looks for and get execution capabilities.
