Atlassian Confluence Unauthenticated Remote Code Execution

This Metasploit module exploits an improper input validation issue in Atlassian Confluence, allowing arbitrary HTTP parameters to be translated into getter/setter sequences via the XWorks2 middleware and in turn allows for Java objects to be modified at run time. The exploit will create a new administrator user and upload a malicious plugins to get arbitrary code execution. All versions of Confluence between 8.0.0 through to 8.3.2, 8.4.0 through to 8.4.2, and 8.5.0 through to 8.5.1 are affected.
