ElasticSearch Kibana白金级破解

[toc]

该方法仅用作学习交流,如有侵权请联系,立即删除

日常开发中可能会想用Kibana的邮件告警功能，但是这个功能默认是收费的，这里介绍一下如何破解白金版Kibana。如果没有大的改版，该破解方法使适用于所有版本。

# 版本信息

ElasticSearch版本：7.14.2

Kibana版本：7.14.2

操作系统：CentOS 7.x

# 准备工作

# 下载反编译工具

tip:

也可以直接下载我处理完的安装包，就不用自己反编译了，版本是：7.14.2

链接: https://pan.baidu.com/s/1s89Jc_VTkYA5cXJcEYcNog?pwd=tznb 提取码: tznb

点击下载 (opens new window)

我系统是MacOS，这里下载luyten-OSX-0.5.4.zip

# 注册License

https://license.elastic.co/registration (opens new window)

除了邮箱其他的随便填写，能收到邮件就可以

# 实现原理

我们申请的license是这样的

{
    "license": {
        "uid": "xxxx",
        "type": "basic",
        "issue_date_in_millis": 1712880000000,
        "expiry_date_in_millis": 1744502399999,
        "max_nodes": 100,
        "issued_to": "ljfd jiejsl (JDK)",
        "issuer": "Web Form",
        "signature": "xxxx",
        "start_date_in_millis": 1712880000000
    }
}

我们可以手动修改到期时间和type，使用我们拥有收费版功能，当然会校验迁移，我们修改Xpack包，使其校验signature失败就可以了。

# 实现步骤

# 下载需要破解Jar包

在ElasticSearch安装包(安装目录)中找到下面这个文件，并下载到本地

elasticsearch-7.14.2/modules/x-pack-core/x-pack-core-7.14.2.jar
1

# 反编译

用Luyten工具打开Jar包

image-20240412162150236

# 修改源码

需要修改两个文件：

  • org.elasticsearch.license.LicenseVerifier
  • org.elasticsearch.xpack.core.XPackBuild

通过Luyten工具将上面两个文件导出

# LicenseVerifier修改

这个类只有两个方法，把他返回结果直接改成返回true。

修改后的内容

package org.elasticsearch.license;

import java.nio.*;
import org.elasticsearch.common.bytes.*;
import java.security.*;
import java.util.*;
import org.elasticsearch.common.xcontent.*;
import org.apache.lucene.util.*;
import org.elasticsearch.core.internal.io.*;
import java.io.*;

public class LicenseVerifier
{
    public static boolean verifyLicense(final License license, final byte[] publicKeyData) {
         return true;
    }
    
    public static boolean verifyLicense(final License license) {
        return true;
    }

# XPackBuild修改

这里将Label_0109: {}中的判断逻辑给删掉了

package org.elasticsearch.xpack.core;

import java.net.*;
import org.elasticsearch.core.*;
import java.nio.file.*;
import java.io.*;
import java.util.jar.*;

public class XPackBuild
{
    public static final XPackBuild CURRENT;
    private String shortHash;
    private String date;
    
    @SuppressForbidden(reason = "looks up path of xpack.jar directly")
    static Path getElasticsearchCodebase() {
        final URL url = XPackBuild.class.getProtectionDomain().getCodeSource().getLocation();
        try {
            return PathUtils.get(url.toURI());
        }
        catch (URISyntaxException bogus) {
            throw new RuntimeException(bogus);
        }
    }
    
    XPackBuild(final String shortHash, final String date) {
        this.shortHash = shortHash;
        this.date = date;
    }
    
    public String shortHash() {
        return this.shortHash;
    }
    
    public String date() {
        return this.date;
    }
    
    static {
        final Path path = getElasticsearchCodebase();
        String shortHash = null;
        String date = null;
        Label_0109: {
            shortHash = "Unknown";
            date = "Unknown";
        }
        CURRENT = new XPackBuild(shortHash, date);
    }

# 设置临时环境变量

# 创建临时目录将反编译java文件长传到该目录

mkdir /opt/temp_es_xpack
cd /opt/temp_es_xpack

# 将java文件编译成.class文件

javac -cp "$TEMP_ES_HOME/lib/elasticsearch-7.14.2.jar:$TEMP_ES_HOME/lib/lucene-core-8.11.1.jar:$TEMP_ES_HOME/modules/x-pack-core/x-pack-core-7.14.2.jar:$TEMP_ES_HOME/lib/elasticsearch-core-7.14.2.jar" XPackBuild.java

# 将.class文件重新打包进x-pack-core-7.14.2.jar文件


mkdir /opt/temp_es_xpack/jar && cd /opt/temp_es_xpack/jar
cp $TEMP_ES_HOME/modules/x-pack-core/x-pack-core-[0-9]*.jar /opt/temp_es_xpack/jar
jar -xvf x-pack-core-[0-9]*.jar
cp /opt/temp_es_xpack/LicenseVerifier.class /opt/temp_es_xpack/jar/org/elasticsearch/license/
cp /opt/temp_es_xpack/XPackBuild.class /opt/temp_es_xpack/jar/org/elasticsearch/xpack/core/

jar cvf x-pack-core-7.14.2.jar .

将修改好的文件放到集群所有服务服务器下的elasticsearch/modules/x-pack-core/目录，替换之前的文件

$ cp x-pack-core-7.14.2.jar /home/elasticsearch/elasticsearch-7.14.2/modules/x-pack-core/
cp: overwrite ‘/home/elasticsearch/elasticsearch-7.14.2/modules/x-pack-core/x-pack-core-7.14.2.jar’? y

# 修改License

修改内容：

  • type：basic修改为platinum
  • expiry_date_in_millis:修改为2019657600000(2034-01-01 00:00:00)这里可以自己定义
{
    "license": {
        "uid": "xxxx",
        "type": "platinum",
        "issue_date_in_millis": 1712880000000,
        "expiry_date_in_millis": 2019657600000,
        "max_nodes": 100,
        "issued_to": "ljfd jiejsl (JDK)",
        "issuer": "Web Form",
        "signature": "xxxx",
        "start_date_in_millis": 1712880000000
    }

tip:

只修改type和expiry_date_in_millis字段就可以了，uid和signature字段不要修改

# 修改ElasticSearch配置

集群所有机器都需要修改配置，然后重启。

将下面这两个设置为false，其他的xpack参数注释掉。

xpack.security.enabled: false
xpack.security.transport.ssl.enabled: false
#xpack.license.self_generated.type: basic  # 这行破解后也不要设置
#xpack.security.transport.ssl.verification_mode: certificate
#xpack.security.transport.ssl.keystore.path: certs/elastic-certificates.p12

重启ElasticSearch集群

# 导入证书

# 方法一：通过Kibana导入

访问Kibana，进入Stack Management->许可管理

image-20240412175332638

上传我们的证书

image-20240412175436322

上传成功后会提示

image-20240412180718976

访问链接也可以看到我们安装的证书信息：http://localhost:9200/_license,返回结果如下

{
  "license" : {
    "status" : "active",
    "uid" : "xxxx",
    "type" : "platinum",
    "issue_date" : "2024-04-12T00:00:00.000Z",
    "issue_date_in_millis" : 1712880000000,
    "expiry_date" : "2033-12-31T16:00:00.000Z",
    "expiry_date_in_millis" : 2019657600000,
    "max_nodes" : 100,
    "issued_to" : "ljfd jiejsl (JDK)",
    "issuer" : "Web Form",
    "start_date_in_millis" : 1712880000000
  }

# 方法二：通过curl导入（该方式暂未验证可行性）

$ curl -XPUT -u elastic 'http://localhost:9200/_xpack/license' -H "Content-Type: application/json" -d @license.json
Enter host password for user 'elastic':           # 输入elastic用户密码
{"acknowledged":true,"license_status":"valid"}    # license写入成功

# 恢复ElasticSearch配置信息

配置文件换成之前的，重启服务即可。

tip：

下面这个配置不要设置成basic，直接注释掉就可以

#xpack.license.self_generated.type: basic

或者改成 xpack.license.self_generated.type: platinum(我没试，我直接注释了)

#
bootstrap.memory_lock: true
bootstrap.system_call_filter: false
network.host: 172.16.24.192
http.port: 9200
transport.tcp.port: 9300
transport.tcp.compress: true
http.cors.enabled: true
http.cors.allow-origin: "*"
cluster.initial_master_nodes:  ["node-1","node-2","node-3"]
#xpack.license.self_generated.type: basic
xpack.security.enabled: true
xpack.security.transport.ssl.enabled: true
xpack.security.transport.ssl.verification_mode: certificate
xpack.security.transport.ssl.keystore.path: certs/elastic-certificates.p12
xpack.security.transport.ssl.truststore.path: certs/elastic-certificates.p12
