Lotus Notes Domino 6.0.2 (linux)  

for the installation it is recommended to add a new 
user like "notes". after this you should log in as 
root install the services. well, after i have done 
this i have noticed the following. 

there are faulty default permissions for the 
important configuration file  
 /local/notesdata/notes.ini rw-rw-rw- notes notes  

 ##############################################  
 by the way  
 /opt/lotus/LPSilent.ini rw-rw-rw- notes notes  

 cat /opt/lotus/LPSilent.ini | grep REM  
 REM This is the silent install ini configuration 
file.  
 REM Please do not modifiy this file unless you are 
sure of what you are doing....  

 pleeeeaaaase do not modifiy it :)  
 ##############################################  

 because we are able to modify the notes.ini which is 
a very important  
 configuration file , we are able to simply delte, 
add or modify keys.  
 here is a great list of all nice keys we could add 
or modify  
 http://www.drcc.com/A55711/ref/notesini.nsf  

 we could modify the CleanupScirptPath to a binary in 
our $HOME which could  
 for example spawns a suid shell next time when its 
executed.  

 we could change the  
 NotesProgram=/opt/lotus/notes/60020/linux  
 to some directory in our $HOME which includes links 
to the needed  
 binarys to start the services in the ServerTask key. 
Then we add a new  
 ServerTask - lets say "Router". Notes will try to 
find a binary in our  
 faked directory called "router" which could spawn a 
suid shell for us.  

the notes services will start as the user 
"notes" (this is recommended), which is able to view 
sensetive files or start and stop the services...  

me thinks the notes install routine should always 
chmod such files automatic for security reasons.
