继上文
补丁
Veeam.Common.Remoting.CSrvTcpChannelRegistration.CSrvTcpChannelRegistration(string, int, CSrvTcpChannelOptions)
用CBinaryServerFormatterSink新的反序列化类替换TypeFilterLevel.Full。
需要用户账号密码。port向上追溯
Veeam.Backup.Common.COptions.BackupServerPort
从注册表取值9395
在日志中发现C:\ProgramData\Veeam\Endpoint\Svc.VeeamEndpointBackup.log只监听了127.0.0.1，所以只能本地提权用。
继续找一下rem的地址 VeeamService
使用https://github.com/tyranid/ExploitRemotingService直接打
