Package: gosa
Version: 2.5.6-2
Severity: critical
Tags: security
Justification: root security hole
The documentation in gosa tells the admin to install gosa.conf under
/etc/gosa/gosa.conf, and to make it readable by the group www-data.
In this configuration file, the ldap admin password is stored in
cleartext. Any process running under the web process can now read that
file, and if the same ldap users was used for authenticating , it would
be rather easy to create a user with root access.
this litle script placed under my ~/public_html/ revealed the password
on my server
<?php system ('cat /etc/gosa/gosa.conf') ; ?>

thanks
This problem is inherited by the way apache/php handles scripts/permissions.
Either disable mod_user [1], or use PHP's safe mode [2] in order to lock down
your system.
From the gosa point of view, this problem can not be fixed - even not by
changing the way gosa authenticates to the LDAP.
