Bug Info

// code start
//.......
$links = serendipity_db_query("SELECT link FROM
{$serendipity['dbPrefix']}references WHERE id = {$_GET['url_id']} AND
entry_id = {$_GET['entry_id']}", true);
//.......
// no checks here...
//.......
if (is_array($links) && isset($links['link'])) {
// URL is valid. Track it.
$url = $links['link'];
}
//......
if (serendipity_isResponseClean($url)) {
header('HTTP/1.0 301 Moved Permanently');
header('Location: ' . $url);
}

//......
// code end

As we see, if we insert some "bad" sql-code into $_GET['url_id'] or
$_GET['entry_id'], server returns in header "Location: xxxx", where is
possible to be an account login/passwd hash
Sorry my english
