Unsecure file permission of ZoneAlarm pro.

Hello list,

Zone Alarm stores its config. files in %windir%\Internet Logs\* . But strangely, 

ZoneAlarm sets the folder/file permission (NTFS) of %windir%\Internet Logs\* to,

EVERYONE: Full 

after its first started.

Even If you try to change the permission to...

Administrator (s): full
system: full
users: read and execute
[these are the default permissions] 

Strangely, the permission again changes back to... EVERYONE: Full each time 

ZoneAlarm Pro (ZAP) is started. I've tested these in zap 4.x and 5.x

        This could prove harmful if we have a malicious program/user running with 

even with a user privilege on the system.

Well a malicious program could modify those config file in a way ZAP will stop 

functioning. This is what ZoneLabs had to say...

---snip-------
anyone could open any ZoneAlarm file 
(assuming it isn't locked), edit it with a hexeditor and 
cause it to stop functioning. This type of modification 
wouldn't be classified as an attack, as you have simply 
modified the file and caused it to not function as expected. 
This is true of any executable or other binary.

---/snip-------
yap, true... but shouldn’t ZAP have some protection against such attacks? instead 

of leaving the permission to " EVERYONE: Full " I wonder if a program could bypass 

ZAP filters using "safePrograms*.xml" [...experimenting]

anyone wanna take this thing to a new level, please go on...
