Product Affected:  
CCH Wolters Kluwer PFX Engagement <= v7.1  
This vulnerability has been reference checked this against multiple  
installs. This configuration was identical across all systems and each  
version encountered.  
Executables/Services:  
  
Pfx.Engagement.WcfServices  
PFXEngDesktopService  
PFXSYNPFTService  
P2EWinService  
Attack Detail:  
The PFX services for engagement install with LOCAL SYSTEM service  
credentials in the directory C:\PFX Engagement\  
  
  
The executables that are installed, by default, allow AUTHENTICATED USERS  
to modify, replace or alter the file. This would allow an attacker to  
inject their code or replace the executable and have it run in the context  
of the system.  
  
This would allow complete compromise of a machine on which it was  
installed, giving the process LOCAL SYSTEM access to the machine in  
question. An attacker can replace the file or append code to the  
executable, reboot the system or restart the service and it would then  
compromise the machine. As LOCAL SYSTEM is the highest privilege level on  
a machine, this allows total control and access to all parts of the system.  
This affects both the server and workstation builds.  
  
Remediation:  
  
Remove the modify/write permissions on the executables to allow only  
privileged users to alter the files.  
Apply vendor patch when distributed.
