Description

This module can be used to upload a plugin on Atlassian Cloud via the pdkinstall development plugin as an unauthenticated attacker. The payload is uploaded as a JAR archive containing a servlet using a POST request to /crowd/admin/uploadplugin.action. The check command will check that the /crowd/admin/uploadplugin.action page exists and that it responds appropriately to determine if the target is vulnerable or not.

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.
