Oracle PeopleSoft Enterprise PeopleTools Server-Side Request Forgery Remote Code Execution Vulnerability Webapp Exploit

A Server-Side Request Forgery vulnerability in the PeopleSoft Enterprise PeopleTools product of Oracle PeopleSoft (component: Updates Environment Management) allows unauthenticated remote attackers with network access via HTTP to compromise PeopleSoft Enterprise PeopleTools. This module uses the previous vulnerability to upload a jsp webshell into the PSEMHUB.war directory to deploy a network agent via the /PSIGW/HttpListeningConnector endpoint. First, the module will validate the vulnerability by using a random string as operation. If the target is vulnerable, the response should be a base64 encoded java string object with the text "Invalid Operation specified" Then, the module will use the REGISTER_WITH_PEERNAME operation, to get a valid peer ObjectName Then, the module will use the HANDLE_MESSAGE operation with an embedded ExecuteProcessActivityCommand object to create the jsp webshell file inside the PSEMHUB.war directory (a web-accessible location). Finally, the module will make a request to the webshell to deploy the network agent. The deployed agent will run with the same user privileges as the target software.
