I'm Spanish native speaker. Let me translate this for you. This is a
free translation. I split it on several paragraphs for better readability.

""" Excuse me, I was trying to use google translator. I speak spanish. I
was explaining you that sometimes there are administrators that need
help to administer forum sections of SMF. In my case I'm part of the
elhacker.net community where there is only one administrator and several
co-administrators. However, the administrator is very wary and he don't
trusts anybody, so he has created an special group of users from the
users panel group called coadmin. This coadmin users are created with
the typical forum administrator rights, with the exception that they are
not allowed to install packages or anything that could allow them to
take control over the forum. """

""" With this security flaw, one of this untrusted "coadministrators"
could access to the config file of the site and could obtain the
database passwords, and then he could get the session hash of the
administrator from the DB. Then he could upload an evil shell like
c99.php """

""" Scenarios like this happen on many forums that I visit like
portalhacker.net or el-hacker.com, among others. I think that this
security flaw is important. SMF is designed to protect directory and
file access, and if it don't works as expected and allows reading any
file then the security implications are high.
I think this is like the typical question of "Is an XSS of high or low
impact?". All depends of the scenario and use case, and in our personal
use cases this is something critical. Thanks for your attention Mr. Kurt """
