KioWare Server version 4.9.6 and older installs by default to "C:kioware_com" with weak folder permissions granting any user full permission "Everyone: (F)" to the contents of the directory and its sub-folders. In addition, the program installs a service called "KWSService" which runs as "Localsystem", this will allow any user to escalate privileges to "NT AUTHORITYSYSTEM" by substituting the services binary with a malicious one.
