我使用的是最新版本的Joomla,v3.6,我很驚訝地發現不支持通過SSL連接到MySQL數據庫。Joomla無法連接到啓用SSL的數據庫
看來,我們需要的是核心的Joomla數據庫驅動程序文件的黑客: /libraries/joomla/database/driver/mysqli.php
更重要的是令人沮喪的是,這個文件看起來用mysqli_connect() ,從我所看到的沒有對SSL連接的內置支持,所以它不會像添加一些屬性那麼簡單。
在我開始黑客攻擊之前,有沒有人成功連接到Joomla的安全數據庫?有沒有我不知道的另一個驅動程序?
我已經包含完整的Joomla DB在此連接功能,以供參考:
public function connect()
{
if ($this->connection)
{
return;
}
/*
* Unlike mysql_connect(), mysqli_connect() takes the port and socket as separate arguments. Therefore, we
* have to extract them from the host string.
*/

$regex = '/^(?P<host>((25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.){3}(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?))(:(?P<port>.+))?$/';
if (preg_match($regex, $this->options['host'], $matches))
{
// It's an IPv4 address with or without port
$this->options['host'] = $matches['host'];
if (!empty($matches['port']))
{
$port = $matches['port'];
}
}

$port = $matches['port'];

$this->options['host'] = $matches['host'];
if (!empty($matches['port']))
{

}

elseif (preg_match('/^:(?P<port>[^:]+)$/', $this->options['host'], $matches))
{
// Empty host, just port, e.g. ':3306'
$this->options['host'] = 'localhost';
$port = $matches['port'];
}
// ... else we assume normal (naked) IPv6 address, so host and port stay as they are or default
// Get the port number or socket name
if (is_numeric($port))
{
$this->options['port'] = (int) $port;
}
else
{
$this->options['socket'] = $port;
}

// Attempt to connect to the server.
if (!$this->connection)
{
throw new JDatabaseExceptionConnecting('Could not connect to MySQL.');
}
// Set sql_mode to non_strict mode
mysqli_query($this->connection, "SET @@SESSION.sql_mode = '';");
// If auto-select is enabled select the given database.
if ($this->options['select'] && !empty($this->options['database']))
{
$this->select($this->options['database']);
}
// Pre-populate the UTF-8 Multibyte compatibility flag based on server version
$this->utf8mb4 = $this->serverClaimsUtf8mb4Support();
