Unsecure file permission of ZoneAlarm pro. Aug 20 2004 02:51AM

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...

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...
