Description

This module exploits a vulnerability in the Kentico CMS platform versions 12.0.14 and earlier. Remote Command Execution is possible via unauthenticated XML requests to the Staging Service SyncServer.asmx interface ProcessSynchronizationTaskData method stagingTaskData parameter. XML input is passed to an insecure .NET deserialize call which allows for remote command execution.

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
