致远M3 server中 mobile_portal接口处存在fastjson反序列化漏洞，漏洞是通过接口/mobile_portal/api/pns/message/send/batch/6_1sp1将恶意payload存入日志中，然后利用/mobile_portal/api/systemLog/pns/loadLog/app.log接口会将日志中的JSON数据进行反序列化的机制触发Fastjson漏洞,造成反序列化远程代码执行。

fofa语句

title="M3-Server"

使用ysoserial生成TomcatCmdEcho回显内存马

java -jar ysoserial-all.jar CommonsBeanutils192NOCC "CLASS:TomcatCmdEcho"

然后将生成的内容进行hex编码

处理去除空格换行

构造payload，将生成的可替换hex处

1、序列化序列化se ria lize() 序列化说通俗点就是把一个对象变成可以传输的字符串,序列化的目的是方便数据的传输和存储。在PHP应用中，序列化和 反序列化 一般用做缓存，比如session缓存，cookie等。常见的序列化格式：二进制格式 json字符串 xml字符串比如下面是一个对象: class S{ public $test="pikachu"; $s=new S(); //创建一个对象 se ria lize($s import javax.servlet.ServletException; import javax.servlet.annotation. Web Servlet; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import java.io.B 但可以发现下面直接调用了toString方法，所以我们直接截取利用链的后一半， 反序列化 ObjectBean并调用toString即可 package com.summer.rome; import com.summer.util.Se ria lizeUtil; import com.sun.org.apache.xalan.internal.xsl Apache Shiro默认使用了CookieRememberMeManager，其处理cookie的流程是：得到rememberMe的cookie值–>Base64解码–>AES解密–> 反序列化 。然而AES的密钥是硬编码的，就导致了攻击者可以构造恶意数据造成 反序列化 的 RCE 漏洞使用docker复现漏洞环境 docker pull medicean/vula...

致远 m3 - server 存在 反序列化 RCE 漏洞，攻击者可以利用此漏洞在远程服务器上执行恶意代码。为了复现这个漏洞，我们可以按照以下步骤进行： 1. 确认漏洞版本：首先需要确定目标服务器上的致远 m3 - server 版本是否存在漏洞。可以通过查看官方公告或漏洞报告来确认。 2. 搭建测试环境：在本地搭建一个与目标服务器相似的测试环境，可以使用虚拟机或Docker等工具来模拟目标服务器环境。 3. 准备利用工具：准备一个适用于该漏洞的利用工具，例如 ysose ria l等，用于构造恶意的 反序列化 payload。 4. 发起攻击：利用准备好的利用工具构造恶意payload，然后向目标服务器发送恶意请求，触发漏洞并执行恶意代码。 5. 验证漏洞利用：在攻击成功后，可以通过查看服务器日志或执行一些系统命令来验证是否成功执行了恶意代码。 6. 报告漏洞：一旦成功复现了漏洞，需要及时向致远 m3 - server 的官方或相关安全机构报告漏洞细节，以便及时修复和防范。总的来说，复现致远 m3 - server 反序列化 RCE 漏洞需要仔细分析漏洞利用的过程，同时要遵守相关法律法规，不得在未经授权的情况下攻击他人系统。
