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.
