Btw., there's a test for the administrators group in /etc/passwd.
I don't see this. I see testing /etc/passwd for the (local) Administrator
USER, and testing /etc/group for the Administrators GROUP, but not
/etc/passwd <-> Administrators GROUP.
More info please?
Function csih_get_system_and_admins_ids(), last test:
csih_ADMINSUID=$(sed -ne
'/^[^:]*:[^:]*:[0-9]*:[0-9]*:[^:]*,S-1-5-32-544:.*:/{s/[^:]*:[^:]*:\([0-9]*\):.*$/\1/p;q}'
/etc/passwd)
csih_SYSTEMUID=$(sed -ne
'/^[^:]*:[^:]*:[0-9]*:[0-9]*:[^:]*,S-1-5-18:.*:/{s/[^:]*:[^:]*:\([0-9]*\):.*$/\1/p;q}'
/etc/passwd)
if [ -z "$csih_ADMINSUID" -o -z "$csih_SYSTEMUID" ]
then
[...]
The function csih_get_system_and_admins_ids is called by
csih_check_access() and requires the above test being successful.
Ah -- those lines are testing /etc/passwd for the Administrator USER.
You originally said 'administrators group'. Hence my confusion.
Now, about csih_check_access() -- without exact knowledge of
csih_ADMINSUID, csih_SYSTEMUID, csih_ADMINSGID, and csih_SYSTEMGID, then
the whole csih_check_access() test can't be computed.
If you make those GID/UID vars "optional" (e.g. not a failure if
missing), and then skip the relevant tests in csih_check_access, you
might as well just abandon the test entirely. Is that what we want to
do? Never bother to check for SYSTEM/Administrator access to the
specified files?
e.g.
/var/run
/var/log
/var/empty
Somehow that doesn't seem right.
